WebMar 28, 2024 · I am learning more about freertos by making a task based program. My problem comes when initializing and configuring the HAL time sources. I read that it is necessary to choose another HW timer as timebasesource and leave Systick for the Freertos. In this case I chose TIM10 (Basic Timer) as the HAL time source. Webthe HAL_SYSTICK_Callback could be implemented in the user file */} For the GCC compiler the “__weak” attribute means that the GCC compile is to use this code for this routine’s default definition, UNLESS the user supplies their own definition for this routine (i.e. without the __weak attribute), in which case GCC compiler is to use the ...
