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.
Excited to speak at #OCX26 this April in Brussels! My session will compare #FreeRTOS, #Zephyr, and Eclipse #ThreadX — helping you pick the right open source RTOS for your next project.
OCX is packed with sessions for everyone in open source, embedded, and beyond.

I'm just here suspiciously making an RGB LED flash in weird ways to test my FreeRTOS code with Queue passing. What makes it weird is I am doing this in a coffee shop.
Hopefully my back to the audience and the fact that I'm wearing my AMD hoodie will make it less weird.
Also why is this LED so bright?!
#FreeRTOS vs #Zephyr is something I hear a lot. The reality is that they're different tools for different jobs. I've written down some of my thoughts after using them both.

Alp Lab Unveils E1M Platform with Multi-vendor Embedded Roadmap
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?
Taking notes on an iPad is pretty good with a paper like screen cover.
Also, I’m going through the Introduction to RTOS course on YouTube. Thanks for the suggestion Ron!

@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.
I am starting my adventures with ESP32 and FreeRTOS.
While trying to find some simple beginner guides and examples, along with in-depth explanations about RTOS concepts and integrating those with the ESP32, I can't seem to find anything online that isn't SEO or AI hot garbage.
Therefore, I bought a book of examples.
From my local bookstore.
Like we did in the olden days.
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.
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
