COMP2 to trigger One-Pulse on STM32L1

Posted by bvernier on 2018-10-12 09:21

Hello,

I have successfully configured TIM4 on a STM32L152 to act in One-Pulse mode, and also successfully set-up COMP2 on the same device, I however can’t figure out how to trigger the One-Pulse mode from the output of the COMP2.

I have tried redirecting the COMP2 output to:

  • “OCxREF Clear” of TIM4,
  • the Input Capture 4 of TIM4,
  • the Input Capture 4 of TIM3 and using ITR2 as the TIM4 trigger (ITR2 is TIM3 when used on TIM4)

none of which worked.

Should any of these configurations work and I just didn’t set them up properly?
Am I supposed to do it differently?
Is there no way to connect the two directly and I should for example start the One-Pulse mode from the COMP2 interrupt?

Thanks in advance!
Ben
