eeeck 84980d2378 Implement hex converter 
- Avoids snprintf
- Can be read from minicom/screen, but it's also friendly for other MCU
- This single function was AI generated
 2026-06-16 19:55:44 +02:00
eeeck 8b1b3b7ff3 Implement safe UART semaphore release inside ISR 
- It uses safe way to release semaphore
- Yields in case task interrupted was of lower priority: UART has
  minimal latency

eeeck ac5d9f6a72 Set CAN event flag and LED thread flag in ISR 
- This is efficient specifically for
  STM32F4x with Thumb-2 IT block
  optimization enabled (-02 or -03)

- To find a way to handle overflows on the FIFO buffer
 2026-06-16 17:57:35 +02:00
eeeck 6446f5209b Remove semaphores in favor of task notifications 
- Less overhead, simpler to manage
- Semaphores are apparently overkill for a simple blink timer

v0.0.2 		2026-06-15 14:33:38 +02:00
eeeck 2c14d095f7 Better way to avoid race condition, only notification lives in CAN task 
- Runs only once
- Only critical notification is inside task
- CAN message during boot will not be lost, instead put inside FIFO0

eeeck ce85e473b3 Move before starting scheduler to avoid race condition 
- If a CAN message arrives during boot time ISR will fire and try to put
  data into xCAN1RxQueue. At that time queue is NULL: calling RTOS APIs
  on NULL handles will cause a HardFault
