Chibios vs freertos reddit. I agree with most of what everyone else is recommending.

Chibios vs freertos reddit It's fully integrated with FreeRTOS, now. can anyone help me to set up a toolchain for this? thanks in Running two threads in FreeRTOS that can both use printf() safely seems like it ought to be a trivial exercise but I'm just not seeing an easy way to get there, at least short of using Newlib with the full _reent structure, and even that seems like not the standard way of doing things - FreeRTOS's creator says he doesn't use Newlib and isn't Why there are so many? I understand FreeRTOS is the most popular one, and maybe it doesn't cover everyones' needs (although even fairly complicated ESP32 wifi and BT stack us running freertos), but why there is so many, free as well as proprietary? What would I gain, if I take for example NuttX over Freertos? A few years back we used freertos in some of our products but moved away from it because it's such a small component that still needs a lot of work to build a project around it (drivers in one side, application frameworks on the other and all the compilation infrastructure to manage it). A good book is "Beginning STM32" by Warren Gay. It might be some large static struct you are initializing to non-zero. It is lightweight, efficient, and highly portable, making it a popular choice for a wide range of applications, including automotive, medical devices, industrial automation, and consumer electronics. Threadx is miles apart though honestly you need to configure it little bit better for get performance from it. By looking at the ChibiOS codebase, I've gotten to know how important it is to document your code using Doxygen, as well as following good style guidelines. e. This started as a help & update subreddit for Jack Humbert's company, OLKB (originally Ortholinear Keyboards), but quickly turned into a larger maker community that is DIY in nature, exploring what's possible with hardware, software, and firmware. Yeah the problem is as soon as one operation cannot be expressed by atomic, you need to use a mutex/semaphore for all. freertos obviously has their own rtos API (xBlahBlah). But I would like to know once and for all what RTOS is available and has been successfully ported to the rpi 3 model B and doesn't require overly complex manipulations in order to be set up?

ChibiOS/RT is a free and open-source real-time operating system (RTOS) designed for embedded systems. now I want to use chibios in the VS code environment. I think the cons you list are minor. conf, . There might be one though. If you want to change MCU, on zephyr, it will be mostly change some DTS. Read the latest articles from… This sub is dedicated to discussion and questions about embedded systems: "a controller programmed and controlled by a real-time operating system (RTOS) with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. ) ZMK can handle it, no problem. But threadx is super stable, its library stack is easy to use and very good. Mar 21, 2016 · What are differences, pros and cons of the three referred real time OS framework, extensions or patches? I want to measure a CPU timestamp counter (TSC), time in nanosecond everytime when a data f Feb 20, 2013 · Looks like FreeRTOS have very high latency on Due or I'm being missing something. Lots of great info on this thread Lots of horrendously wrong information in here. Nov 13, 2024 · ChibiOS : My brain thinks of it as FreeRTOS but with more complex networking options available. zip Google Code Archive - Long-term storage for Google Code Project Hosting. an abomination imho. Tasks and inter-task sync and communication is basically the only thing FreeRTOS supplies, so the learning curve is not that bad. There are new and improved examples for all of these systems. The result felt bloated and I did not enjoy FreeRTOS APIs. Speaking of FreeRTOS, you can take a look at the QP/C port to FreeRTOS as well as the examples. That said, you still need to maintain dependencies to external libraries, and to make sure chibiOS ends up in your binaries. In addition whenever you build your firmware, the usage of the different memories is provided. Welcome to /r/AcerOfficial, Reddit's biggest acer related sub. Let’s explore. Though I didn't think the difference was significant enough to justify a migration of a legacy code base. " Using the MCU directly implies you intend to completely ditch the Arduino software and use something else. As far as the integration goes: The ESP32 is organized like a stack of software. Azure RTOS is a renamed ThreadX which does basically the same thing as FreeRTOS with a bit more sanity (as it was a commercial product before Microsoft acquired them). And particularly to understand why sometimes you'd use one, vs, why other times you'd pick a different path from the general range of options represented by: bare metal MCU Mar 18, 2021 · This becomes also apparent when it comes to simply getting started with a new ChibiOS project. It’s MiT licensed so feel free to steal whatever you need :p We’re using tup instead of make but essentially what you want to do is have a rule where all . I'm used to freertos and safertos terminology) that then needs this data can just assume the buffers have been filled via DMA. objdump is another good way to see what’s going on in the elf file. dtsi files, every driver hidden away somewhere in an amazonian jungle of struct function pointers and layers upon layers of abstractions, including even ISRs (which, again, is an abomination). And makes the remaining 5% really really hard. Whereas FreeRTOS as we saw earlier can comfortably be just the RTOS within a HAL like CMSIS-RTOS FreeRTOS does support a tickless idle, though it is really to help reduce power consumption rather than provide more precise task timing. If you need technical help or just want to discuss anything Acer related, this is the right place for you. The problem with FreeRTOS is that it's just a simple task switching kernel, these other offer so many stacks and libraries for free that is very helpful when working alone on a side project. but a f***** rtos that wraps everything in . As the low-level technology, correct behaviours and decent performance of an RTOS play a vital role in guaranteeing such constraints. The network stacks appear to be better thought out and implemented. It stays out of the way and This sub is dedicated to discussion and questions about embedded systems: "a controller programmed and controlled by a real-time operating system (RTOS) with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints.

Like spend ages figuring out exactly how the HAL works so you can slide the extra little bit you need in without disrupting the system. I feel like freeRTOS is honestly not comparable to threadx. While I was trying to structure my code better and get some ideas I looked into Zephyr RTOS I was impressed by the amount of drivers it provides and its well designed abstracted api. FreeRTOS_vs_ChibiOS ##/evaluate_code. This sub is dedicated to discussion and questions about embedded systems: "a controller programmed and controlled by a real-time operating system (RTOS) with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. FreeRTOS is at the bottom forming the foundation of the stack. What would be the drawback of using a single 480MHz core vs using 2x240MHz cores if using proper threading inside an RTOS like ChibiOS? I am also struggling to see the "real gains" of using Zephyr vs freeRTOS. But for Embassy, the ability pass messages and signals around in code and awaiting a "rising edge" of a signal or message channel feels very intuitive to me. If you want to understand what a modern microcontroller support ecosystem looks and feels like, try Mbed or maybe ChibiOS. Jan 25, 2024 · Currently, I am working on one project based on freertos and stm32 hal, but now i decided to switch that project to chibios RT/hal. 4. org on Fri Jul 17 11:57:00 MST 2015 > "what are the differences between eCos and FreeRTOS?" is a very broad question that could have a one line answer, or a 50 page answer, depending on how much detail you wanted to go into ;o) Ultimately they are both RTOSes, so perform a similar function. Definition of RTOS: A real-time operating system (RTOS) is an operating system (OS) intended to serve real-time applications that processes data and events that have critically defined time constraints for the system under control to perform as required. Choosing the right RTOS for IoT platform, Milinkovic et al, INFOTEH-JAHORINA Vol. FreeRTOS has very fast context switch time on Due. Then you can use DMA to shovel that data onto a buffer. It sounds like your best choice is to get an STM32 F0 Nucleo board that is pin compatible with Arduino headers (for learning various hardware), provides unrestricted use of Keil MDK (to learn a commercial IDE), is fully supported by STM32 CubeIDE (to learn a Vendor specific IDE), is ARM Mbed Enabled (in case you want to go back to an Feb 25, 2019 · Not sure where I should post this issue, but it is related to Arduplane, so I guess this is the right place. Sep 25, 2017 · Having looked at both implementations to a extent, my expectation was that FreeRTOS and ChibiOS would be comparable in terms of performance - with ChibiOS having a slight edge. I am not aware of another Arduino build on top of FreeRTOS. I took something already made by Erich Styger famous for is work MCU on Eclipse. Nov 7, 2011 · Personally I prefer ChibiOS/RT to FreeRTOS on the Arduino. " FreeRTOS_vs_ChibiOS. There are lots of them like ChibiOS, Zephyr, FreeRTOS, NuTTx, RTEMS, eCOs, etc. the tasks/queues are fundamentally implemented in FreeRTOS, but exposed through the ESP-IDF so they can be used with the rest of the ESP32 specific Hardware and software maker community based around ortholinear or ergonomic keyboards and QMK firmware. I used its tcp and http stack marvelous. I have recently started an IoT project using FreeRTOS. A minimal FreeRTOS setup is probably tiny (4KB?). 1 : Getting and configuring the code. to integrate from the get-go. FreeRTOS also uses a copy-left license so migrating to that wouldn't help. 2 to the Arduino IDE. 1. if you are using stm32's cubemx to generate the freertos stuff, then they will incorporate translation functions to translate the cmsis api into the freertos api. More experience required on my part to get a better taste of it though. c files get compiled with gcc, all . The task (cmsis rtos seems to call tasks threads. We did exactly this in the ODrive Robotics code. reddit. In general, however, FreeRTOS is dominating the embedded RTOS market, with something like 20% of new projects using it, far more than any single other RTOS -- and so you are likely to find equivalent open source projects for FreeRTOS as Microsoft provides with ThreadX. Zephyr has a driver layer, filesystem, networking, logging, etc all designed. It took me about a week or two to really get used to it, but with support from my partners. 3. Mar 18, 2021 · Perhaps more accurately, FreeRTOS could be summarized as a multi-threading framework targeting low-powered systems, whereas ChibiOS is more of a full-featured OS, including a hardware Zephyr brings a lot more than FreeRTOS: build system, test framework, device drivers, communication stacks FreeRTOS is pretty basic compared to zephyr, and its API has aged. 0 and ChibiOS/RT 2. (It works as PWM output though) The last Given your petulant exaggeration and clear display of not having researched the topic at all, like e.

I would classify it somewhere between FreeRTOS and Zephyr. Because I couldn't find a single "main" repository for drivers for FreeRTOS. The other big advantage of Zephyr over FreeRTOS is that it already supports multiprocessors. As a member of our community, you'll enjoy: 📚 Easy-to-understand explanations of business analysis concepts, without the jargon. I used ChibiOS first before I started using FreeRTOS with ST's CubeMX software. " Feb 24, 2021 · ChibiOS is quite nice but is crippled by antediluvian source control (svn? come on it’s 2021!), triple licencing (apache, GPL/proprietary) and it comes with it’s own build system (makefiles). And if you end up needing tasks/threading you may as well use FreeRTOS. ChibiOS is a bit faster but I don't think this is your problem. But besides the API part, it's purely subjective and the bloat might have (and probably did) originated from HAL. 14, 2015: comparison of FreeRTOS, ChibiOS/RT, Erika, RIOT FreeRTOS Architecture Improve this page Dec 17, 2012 · The latest version of ChibiOS/RT and FreeRTOS are now located here: Google Code Archive - Long-term storage for Google Code Project Hosting. Our friendly Reddit community is here to make the exciting field of business analysis accessible to everyone. For FreeRTOS and others, the RTOS typically is thrown over the wall, the vendors package into their tools/distribution. and zephyr being the ONLY choice when I usually use ChibiOS as an RTOS but have not found a way to use it in a multicore configuration, which I have done with the ESP32 MCUs using FreeRTOS. Compared to Azure, FreeRTOS is not designed to be used in safety-critical systems, doesn’t have any certification packs, and whereas Azure provides a add-on modules that are designed to work with RTOS — for GUI, TCP/IP networking, USB, file system, etc — you’d have rely on third-party modules for FreeRTOS if you needed those things. Last one I used was uCOS2 running in a DOS shell under Windows 98! ChibiOS HAL with FreeRTOS v10 This forum is about you. Hello I have seen this question being asked multiple times in the past. The ESP32 series employs either a Tensilica Xtensa LX6, Xtensa LX7 or a RiscV processor, and both dual-core and single-core variations are available. Mar 21, 2021 · Something like ChibiOS (‘Chibi’ meaning ‘small’ in Japanese), or FreeRTOS (here no points for originality). Step motor have priority 1, scrolling text - 2. Hackaday serves up Fresh Hacks Every Day from around the Internet.

My debug configuration looks like this: { "type": "cortex-debug", "request" Jun 15, 2016 · Content originally posted in LPCWare by www. which pins are rows vs column, etc. It provides basic operating system concepts like tasks, mutexes, queues, etc. " zephyr. I have not yet developed with only the API (sometimes I use the API with RTOS specific commands). I know Fitbit (now Google) uses nuttx on some devices. AVR boards, Due, and Teensy 3. I have now discovered 2 inconsistencies between NUTTX and CHIBIOS: Connecting both the Airspeed sensor and Lidar on I2C doesn’t work on NUTTX, but works on CHIBIOS Camera trigger set as relay on AUX-OUT 4 works on NUTTX, but not on CHIBIOS. They deal with classes well enough, but the task has to be a separate piece of C++ code and not in a class. So, in comparison, do you find that Zephyr, FreeRTOS, ChibiOS, etc all offer better HAL access? Ultimately part of my reason for wanting to use an RTOS on STM32 is to escape how clumsy and buggy the ST HAL is, so having a better replacement API is kind of a plus for me, but I can see what you mean in terms of having to rewrite stuff that doesn't fully meet a production spec. Nov 16, 2012 · For starters, here is my step one to get FreeRTOS on the Teensy3. Saves CPU time. Rather than the question of if you should study FreeRTOS specifically what's important is to have some understanding of the "idea" of a compact MCU RTOS in general. Feel free to discuss anything is related to embedded and electronics, your awesome projects, your ideas, your announcements, not necessarily related to ChibiOS but to embedded in general. So the RTOS trade-offs really start with the hardware selection (what kind of features/peripherals you need and how the processor will interface with other components). Jun 3, 2021 · FreeRTOS vs ThreadX vs Zephyr. IMHO (and speaking as one of the original authors of several billion-shipping RTOS-like things), FreeRTOS is not a good use of your time. Nov 13, 2024 · Perhaps more accurately, FreeRTOS could be summarized as a multi-threading framework targeting low-powered systems, whereas ChibiOS is more of a full-featured OS, including a hardware abstraction This repository contains all code needed to build the ChibiOS HAL together with the FreeRTOS real-time operating system. Also that was like 2 years ago, so things might have changed. . ----- License ----- What is the primary difference between commercial RTOS like INTEGRITY, uCos, VxWorks and the like, compared to stuff like FreeRTOS, ChibiOS… So I recently shifted my project from freeRTOS to threadx. I'd do the DMA approach. 1 to that end and want to compare both I've already released another product using Arduino and FreeRTOS, but it seems everyone says ESP-IDF has a huge gain over Arduino. The ChibiOS/RT source has comments describing how compiler options can change performance. Since these are preemptive kernels, careful design is required to avoid problems with normally single Jan 29, 2013 · I have posted the most recent versions of NilRTOS, ChibiOS/RT, and FreeRTOS on this site. FreeRTOS vs ThreadX I thought it was going to be easy to use VS Code as that seems to be the status quo- but all of the tutorials/extensions/examples I have found via Reddit/Google have been pretty hacky/hastily strung together (including the official STM32 extension). 0 as Teensy3-RTOSbeta20121116. I have used Chibi Studio for a basic understanding of how to compile and create board files,s, etc. com/r/embedded/comments/6b8x4t/anyone_did_a_nuttx_chibios_freertos_comparison/ And final word. FreeRTOS is the product of an EE going "what's the minimum I can do to get some threading on my micro?". Now, critics question if either of the systems will remain truly open source, especially since both parent companies have previously engaged in lock-in practices. HAL for STM32 Standalone and with FreeRTOS. If you are planning to work with Nordic Semiconductors nRF there's no way around zephyr. Take care. There's very little overlap in hardware support between the two "types" of RTOS -- FreeRTOS doesn't run on many SoCs and RTLinux doesn't run on many MCUs. googling for "freertos static allocation" would've given the link in my first post as the first result, your attitude comes off as you having already decided that FreeRTOS is bad and should feel bad and you're just here looking for an echo This sub is dedicated to discussion and questions about embedded systems: "a controller programmed and controlled by a real-time operating system (RTOS) with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. My last project had a single MCU running 7 or 8 tasks, monitoring at least 20 sensors, controlling a half dozen high speed PID loops, while running a small webserver with LWIP and giving diagnostics over a UART DMA. I would recommend both for business use, however the ChibiOS RTOS itself is GPL though you can purchase a commercial license. UART) which I find confusing. Sigh, you're totally missing the point of mechanical keyboards . The reality is that we don't need microsecond or better timing on most things, and for the small number of things that do need it, a hardware timer + ISR is fine. ChibiOS is in the one microsecond range and FreeRTOS is under two microseconds on Due. On top of FreeRTOS is the ESP-IDF. Stmicroelectronics has Stmcubeide that makes using FreeRTOS easier. The ESP-IDF w/ FreeRTOS left a bad taste in my mouth due to a obtuse scheduler and bad background task prioritization. zephyr is awesome for high school children and hobbyists everywhere. 7K subscribers in the hackaday community. Contribute to DapengLan/FreeRTOS_vs_ChibiOS development by creating an account on GitHub. If you need a small, fast, deterministic system then ChibiOS is probably the finest open-source RTOS+HAL. ili tako nesto za rad, nije neko But when compiling a Linux kernel, you're only selecting from options and not writing custom code, so you can see how that idea can be applied to keyboards, by considering the keyboard firmware as analagous to a Linux kernel. Perhaps more accurately, FreeRTOS could be summarized as a multi-threading framework targeting low-powered systems, whereas ChibiOS is more of a full-featured OS, including a hardware abstraction layer (HAL) and other niceties. g. With other solutions, you are running a different tool stack for every manufacturer. zavisi sta ces da radis i ko je oko tebe, realno ako neces ti dizajnirati sistem vec samo programirati sve sto te zanima je da procitas datasheet da bi znao kako da pricas sa raznim komponentama takodje moras da znas sistemsko programiranje, da razumes envelope, semafore, mutekse etc etc . If you can't try both I would definitely go with an RTOS since you already got the feel for bare metal. RT vs NIL Comparison and Performance RT and NIL are the two RTOSes part of the ChibiOS families, they share most of the API and are very compatible but the internal solutions are entirely different and driven by different requirements: What about RTX/Mbed ? Either way, the cost will roughly be the same. As long as you're only doing basic stuff (e. If you have troubles because of task switching latency/cost you may have other issues like too high switching frequency or too strong requirement for a task and part of the processing should be delegated to an interrupt/higher priority task. This port also uses the native FreeRTOS message queue for passing events into active object tasks. As well to help those with common tech support issues. In contrast, the Zephyr RTOS has a modular, configurable design and offers a rich set of subsystems and libraries. It mostly gives you threads and a useful library of things like buffers, semaphores and software timers. Have the linker generate a map file and see what’s taking space. The only things I've found so far is the Zephyr build system and some small stuff that other RTOS do not support (NFC is a good example). Have a look at the STM32 Arm boards from ST and start looking for an alternative tool chain - preferably one that is RTOS based. Dec 11, 2018 · I am going to start a port of ChibiOS for both 32 and 64 bit on all the various models of the Raspberry Pi I recently completed the conversion of FreeRTOS 10. For example, using the I2S bus on an ESP32, it's very difficult to get it not to skip under the ESP-IDF. With Zephyr, the experience between MCUs from other vendors is very consistent. I only read that TI-RTOS drivers could work on FreeRTOS and I could use CCS. EDIT: If you just want to use freeRTOS to write a realtime application, it is very straight foreard and therefor recommended by me. The only FreeRTOS system I've worked on was STM32+HAL+FreeRTOS. I've used both for hobby projects, though I've used the ChibiOS HAL professionally. These tests measure the performance of a few statements in tiny functions. View community ranking In the Top 1% of largest communities on Reddit. This will create a static library containing FreeRTOS. It uses less RAM and the faster performance is not due to assembly code or tricks that make it hard port, it because of elegant design by Giovanni Di Sirio. If you go with STM32, ChibiOS has a really nice HAL and the code is clean. Contribute to SiChiTong/ChibiOS-FreeRTOS_Examples development by creating an account on GitHub. On freertos, could be way more complicated depending on how modular you made your application. If you just want a run-loop and some interrupts, you basically won't know FreeRTOS is there. OS overhead should be a small percentage of CPU use in any ThreadX (now Azure RTOS) is basically FreeRTOS that wasn’t hacked together ad hoc. " To be honest there are probably plenty of features in FreeRTOS that I never utilized, that would have made my experience there better. It made my systems less "realtime" than they needed to be. What it seems to me is that Zephyr is "the new thing" and has a lot of "big names" behind it This sub is dedicated to discussion and questions about embedded systems: "a controller programmed and controlled by a real-time operating system (RTOS) with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. Due to these concerns, some critics believe there could be a popular challenger in 2023. https://www. It really depends on portability, for you are designing highly portable modules that require some RTOS interaction than it would be good to learn/use this. The SPI controller should have a DMA request signal in this case. This paper studies the real-time performance and behaviour of two popular RTOSs used in drones, presenting both quantitative Mar 28, 2023 · Initially, we leveraged FreeRTOS as our underlying operating system. While FreeRTOS is a popular choice for embedded applications, we found it to have limited library support and lacking in overall flexibility. E. FreeRTOS isn't abstracting away too much. I was assigned to implement a self suspendimg task support for freeRTOS and two scheduling algorithms for such task sets. Imo it’s more sane than FreeRTOS but it doesn’t have a driver API so you’re in the same place as you would be otherwise. I have ported FreeRTOS version 7. Lots of chips are starting to come with multiple cores and there are extensions to FreeRTOS to handle it (See the ESP32 port) but last I knew it wasn't standard and part of the base FreeRTOS. FreeRTOS is a scheduler and some primitives to talk between the tasks and that's about it. If you don't want to, or never will, use C++, then it's going to be easier. Nov 7, 2011 · Variations due to compiler settings in tests like this are to be expected but are not important. dts, . " FreeRTOS has tasks and co-routines, so it kind of does the whole protothreads bit, shares the stack but it also has the scheduler backend. ChibiOS can be considered a component of a project, you are expected to include it in your project, it’s easier to understand and adapt as it’s developed/tailored mainly for STM32. cpp files are compiled with g++, then everything is liked together with g++. they then call the cmsis rtos api instead of the freertos api. Also comparing something like zephyr against FreeRTOS is ignoring the fact that FreeRTOS is basically just a scheduler. However both OSes have a commercial license option available. I agree with most of what everyone else is recommending. cmsis specifies an RTOS API (and they actually have their own rtos too). I like the guy very much, he takes the time to reply on every comment or question post ed on the site RT vs NIL Comparison and Performance RT and NIL are the two RTOSes part of the ChibiOS families, they share most of the API and are very compatible but the internal solutions are entirely different and driven by different requirements: FreeRTOS vs Active Object I started working a week ago, at a company that manufactures parts for medical devices. An example project is included in the folder example. Sep 5, 2023 · This is an interesting comparaison between nuttx chibios and freertos. I've been able to make an ethernet modbus node using a w5500 in few minutes with the Arduino stack, but then I tried to do it on ESP-IDF and with 5 hours in, still not able to make it happen. They were working on it though. These systems are packaged as Arduino libraries so they can be used with other Arduino software. I have two: The HAL does the easy 95%. Code generation for a single statement can change the results like this. It is a framework for interacting with the ESP32, bridging together the ESP32 specific functionality and FreeRTOS. 0 are supported. In the demo from the FreeRTOS page, driverlib contains drivers but they're organised by modules, instead of peripheries as usual (e. they The ESP-IDF is a bunch of C code built on top of/alongside FreeRTOS. But FreeRTOS is uniquely difficult because you have to provide two sets of APIs for everything: the "regular", task-level API and the "FromISR" ISR General information about FreeRTOS 2024 RTOS Performance Report (FreeRTOS / ThreadX / PX5 / Zephyr) - Beningo Embedded Group 2013 RTOS Comparison (Nucleus / ThreadX / ucOS / Unison) - Embedded Magazine v it's related to cmsis like you said. 5. FreeRTOS. You can edit the Nov 16, 2012 · I have posted a first beta of two Real Time Operating System kernels for Teensy 3. verovatno ces koristiti neki freertos ili neki embos, chibios . With the evolvement of various drone platforms, the constraints of such embedded systems are getting more and more strict and specific. If your tastes run to the slightly more baroque and Posix-y, NuttX or RTEMS. It's been years since I've used a "commercial" RTOS. And of course with ChibiOS for personal projects. Overview of ChibiOS/RT. First, you should run make in the FreeRTOS directory.

Nov 10, 2022 · I am trying to debug a ChibiOS application using the OpenOCD debug server (on an STM32 using ST devboard) and noticed a minor oversight in the config validation. The evaluation code to compare the five functions between FreeRTOS and ChibiOS/RT, context switching, interrupt handling, semaphore acquire time, priority inversion and memory footprint. A place dedicated to discuss Acer-related news, rumors and posts. I learned that the software developers use a non-preemptive kernel/scheduler based on active object or event-driven object pattern instead of FreeRTOS which already has a scheduler and lots of other possibilities. The actual goal is to minimise the number of actual keys so they barely cover the alphabet, silencing those keys to the point the only noise they produce is a dull thud and relying on a highly customised keymap that takes 3 weeks to learn to use properly, is impossible for anyone but you to use and for some reason requires 6 keys Basic Examples of FreeRTOS with ESP32 and ESP-IDF. STM32F4 with FreeRTOS. I am very excited by results of running NilRTOS on Uno Arduinos. While I like CubeMX and the code that it generates, I find it easier to read through the ChibiOS code. FreeRTOS is also worth learning, but I personally despise it, mainly because I had to use it in university for ridiculous and brain-dead assignments that were tailored to make students suffer. Personally, I chose to ditch ChibiOS because of the license. I think you cannot get away with a circular buffer (or in general a FIFO), as you need to access "start index" and "end index" together when you want to calculate how many element there are left or used (you can switch around variable, but in the end you still need to access 2 In Zephyr you can invoke the ram_report or rom_report target to get a detailed memory usage (i. lvri dqgljju pqqvmcwp ckcjl bqorxw mznu lnelu hojml gjmh eoprcvb phu nami szxvkuo idhf kkllbf
