Hal stm32 printf

Web1. When you use a HAL_DELAY you have to keep in mind that the counting is done in the interrupt routine SysTick. If you call the HAL_DELAY in the interrupt that has greater priority, then systick counting is stopped. So the HAL_DELAY gets stucked in the endless loop do...while, because the systick isn't counting. Webprintf("Hello %s\r\n", "world"); To make this work you have to implement a special function (_write) to tell the C-library how to process the output from the printf function. int _write(int fd, char* ptr, int len) { …
