eeeck 59b0aca092 Refactor: implement data relay from vCANLoggerListen to xUARTQueue 
- No RTOS event, just queue put and get: cleaner way to send data and
  more clear separation of concerns
 2026-06-16 22:09:49 +02:00
eeeck 5f11cf5213 Revert decision on moving CAN event flag outside ISR 
- Would have caused destruction of the queue data itself
 2026-06-16 21:34:43 +02:00
eeeck 74bf4bde77 Implement identical queue drain for CAN2 to that of CAN1 2026-06-16 21:29:32 +02:00
eeeck 3691918196 Non-blocking on CAN1 queue check 
- Check queue instantly
- Use DMA to move tx_buffer to UART peripheral
- Use a semaphore to DMA is being done, to avoid moving to next loop
  iteration and overwriting tx_buffer
- HAL_UART_TxCpltCallback will release semaphore when DMA done
 2026-06-16 21:27:52 +02:00
eeeck 79f317cec5 Wait until CAN1 or CAN2 save anything to FIFO buffer 
- Moving CAN event flag to vCANLoggerListen to avoid possible race
  condition and to make ISR leaner
 2026-06-16 21:06:32 +02:00
eeeck da1c13fcb0 Fix comment blocks and function descriptions 2026-06-16 21:02:15 +02:00
eeeck 59274272d3 Remove not useful comment blocks 
- Not really used by CubeMX so worth removing

- 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

 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
