STM32L0 - Microseconds delay function

[pbdiazam]

Hi everyone!

I am using a STM32L0 board and I need to read data from a sensor. To be able to do this, I need a microsecond delay function, but I could not find any way to achieve this.

I need some help! Thank you!

Free run a TIM at 1 MHz (or higher) and delta the count measurement until it reaches the span of the delay required. Pretty basic stuff.

True, unless you need low microseconds. Here I would use inline asm counter code or insert NOPs

If you need nano-second realm stuff clock the TIM faster. Heck even at 24 MHz you can get well sub-microsecond

On the non-CM0 parts consider the DWT_CYCCNT

Timer and counters aren't afflicted by interrupt loading compared to fixed iterations loops with NOP, etc.
