FreeRTOS calls
Log from Over-engineered LED strip controller
I guess I'm going to seem pretty fickle about the software environment, but it's really born of ignorance rather than wishy-washy-ness.Earlier, I commented that I would probably use Lua so that I could take advantage of multi-threading to simplify the...

Progress - FreeRTOS and keypad.
Log from Project 'Landlord'

FreeRTOS tasks and queues
Log from PIP-Watch
In my previous homebrew projects I did not use any operating system in the embedded processors. Software was programmed on a bare-metal hardware. In my Talking Clock project I created a simple cooperative event-processing abstraction layer, but it was...

Working with FreeRTOS
Log from ESP8266 Native
I've been re-compiling my demo apps with the new FreeRTOS SDK. This is a lot easier to use for network access, if you are used to a BSD style socket interface (which I am).So far, so good. One thing I've noticed is the lack of support for reading from...

Testing Amazon FreeRTOS
Log from FIMble
After doing some research, I think the best experience will be to use Cypress’ Amazon FreeRTOS. I tried looking into mbed OS but the documentation for this board is not clear and it seems it doesn’t have an easy way to import into ModusToolbox. As a...

The Beating Heart: FreeRTOS
Log from NTP Clock Based on STM32H735 Discovery Kit
My clock is built around FreeRTOS. FreeRTOS is an open-source real-time operating system for embedded devices. It provides timers and synchronization functions, amongst many other capabilities, and it is a fully preemptive multitasking...

FreeRTOS + TinyUSB + Multiaxis support
Log from Open FFBoard
There was a long time between the last 1.2 and current 1.3 firmware release. The reason is a huge internal change porting everything to support freertos and using TinyUSB as a USB backend instead of the customized ST middleware examples which had to...

Controlling the 7 motors: Installing FreeRTOS
Log from Building the Thor robot
Thanks to Danny I discovered FreeRTOS that probably will make controlling the 7 stepper motors fluently. It is a small "Real Time Operating System" (RTOS) designed for small devices.I went to the FreeRTOS web site but when I unzipped the files, I did...

Xling v3.1 - an animation demo, more checkpoints, 4-wire SPI and FreeRTOS
Log from Xling
Almost a month and a half passed since the previous update (not so much comparing to v0.3, eh?) and I'm here to share some details regarding the overall progress. First of all, I've finally got rid of the leading zero in the Xling PCB version because...

Resetting Bug
Log from OSHWatch
I have some further thoughts into this resetting bug; I've realised the watch doesn't actually report a brown-out reset, and it ONLY happens after leaving the watch in sleep mode for an extended amount of time (>1 hour). Furthermore, the scope trace...

Second thoughts about the SDK hacking approach
Log from Bare metal second core on ESP32
Why didn't it work? I've been wondering why my SDK hacking attempts did work so poorly. But, after thinking a bit about it, it should have been obvious from the start: Synchronization functions heavily depend on the scheduler! I wanted my bare-metal...
