FreeRTOS WS2812 (Neopixel) RGB LED (part 2)

Adding FreeRTOS to driving Neopixel WS2812 addressable RGB LEDs using a RP2350. We will be adding FreeRTOS into the mix but keep the PIO state machine and DMA code from the previous project.

Вводим рейтинг по алкоголизму

Алкометр, который сохраняет результаты на веб-сайте в историю, а также позволяет соревноваться с другими пользователями в недельном рейтинге. На проект ушло более 400 евро, один год и несколько ревизий. В статье расскажу о долгом и затратном пути к финальной версии и о том, какие ошибки были совершены.

[Перевод] Ghidra для реверса прошивок: практический гайд по восстановлению логики бинарника

В прошивках редко есть удобные символы и понятная точка входа, зато почти всегда остаются следы: строки, таблицы адресов, магические значения, обработчики прерываний и вызовы RTOS. Разбираем, как использовать эти зацепки в Ghidra, чтобы постепенно превратить сырой бинарник в осмысленную карту функций, данных и связей между ними. Понять Ghidra

🚀😂 Oh great, yet another guide promising the ✨magic✨ of running #Rust on an ESP32-S3's second core! Because who doesn't love a weekend full of 'why won't this #CMake script work' and 'what even is an #assembly trampoline?' 🙄 Just pin a #FreeRTOS task and call it a day, hero. 🛠️

STM32 + FREERTOS + SDIO + FATFS

Подключение SD-карты к микроконтроллеру — классическая задача, но путь от инициализации аппаратного интерфейса до работы с файлами в многозадачной среде усыпан скрытыми камнями. В этой статье я на практике разберу полный цикл интеграции SDIO, файловой системы FatFs и ОСРВ FreeRTOS на STM32.

AMD launches Ryzen AI Embedded P100 and X100 processors with up to 50 TOPS of AI performance

Does anyone knows good way to find #gig opportunity for software dev? I'd like to avoid pitfalls of well known platforms. I can do:
- #Rust CLI/Dev tools, APIs
- #C code (#FreeRTOS, #Zephyr, #Linux including some #drivers or #v4l2)
- #Cpp C++ code
- #Bash or #Python scripts, tools
- #CI workflows (GitHub, GitLab)
- #Yocto layers
- #Debian packaging + #DKMS

Anyone has experience in getting hands on small projects?

Edit: I can #teach / #training Rust or C++.

@ploum Je ne comprends pas « Basé sur Android, le Kompakt ... » [1] et "I appreciate Mudita changes to Android" [2].

#Mudita dit [3][4] que le #MuditaKompakt est basé sur #FreeRTOS [5] (licence MIT = licence Expat).

Les apps sont-elles d'Android ?

En partie, c'est pas encore du libre [6][7].

@sigismundninja @Alonely0 @hackernoon We wrote embedded product on #Cortex M7 written in full in C++ (#Cpp), except glue code to #FreeRTOS. We disallowed new, delete, raw pointers, etc thoroughly filtered in PRs (tedious job). The only #haisenbug we had was temporaries of packed object (don't do that in C++). Everything else we were fixing using unit tests.

But I promise you not all businesses follow as strict policies as we did. In #Rust it's millions times easier.

Hoy estuve ensayando #FreeRTOS en un #STM32 para ser preciso en un #STM32F411 en una placa discovery. Estoy usando #libOpenCM3, #PlatformIO sobre #Linux. El uso de #SoftwareLibre no es una opción, es un deber. Especialmente en educación, liberarnos de las herramientas privativas, matenidas por una empresa, no son una opción viable. El software creado, mantenido y utilizado por una comunidad es un valor ético y moral que debemos tener siempre como bandera.

Acabo de abrir una puerta nueva para mí. FreeRTOS era algo que me debía desde hace mucho tiempo y por fin me hice un ratito para poder probarlo y aprenderlo. A partir de ahora es toda un área de conocimiento importantísima para aplicar en sistemas críticos de tiempo real multitarea.

Les dejo el código en github.

STM32 Tutorial #30 - Sine wave (Dual DAC) with DMA under FreeRTOS

In this exciting video we will generate TWO beautiful sine waves on both of the STM32F405 DACs (Digital to Analogue Converters). We will be using DMA and let FreeRTOS handle the scheduling of the callbacks. Sampling rates in excess of 1 Msps is possible.

When you initialize the FreeRTOS task before the Queue using it, and wonder why *sometimes* your system crashes.

#embedded #programming #microcontroller #freertos

I'm writing probably the silliest task scheduler for the #esp32 doing some cooperative multitasking.

Each task is a sequence of subtasks, essentially methods. The task can potentially yield everytime it switches to the next subtask.

This whole thing started because I wanted something quick and was to lazy to switch to #freertos or #zephyr but Im in so deep it would probably have been faster.

Now this whole thing got me thinking, could I write my own preemptive scheduler for the #esp32
