Multiple choices for microsecond delay, which one's better? Hello, First time using the forum so apologies if I mess something up...Long story short I wanna get a microsecond delay, I know 2 ways of doing it:1) I can start a timer with default cube values and use a function like:void delay (uint16_t delay)
{
__HAL_TIM_SET_COUNTER(&htim1, 0);
while( __HAL_TIM_GET_COUNTER(&htim1) < delay);
} to get the desired delay, or2) I can start timer, set its prescaler value to specific frequency with interrupt turned on, drop it down to 1khz/mhz for easier calculations and in timer callback function have some variable increase by 1, then use it in different function as time measurement, something similar to this:uint8_t counter;
void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim){
counter++;
}
void main() {
while(){
if(counter==20){
// do smth
counter=0;
}
}
}I have used both of these methods previously and know one is running in blocking mode, other in non-blocking mode. So that got me wondering, what other differ
