Hello,
I have a question about STM32F407.
I was wondering how to software trigger (not external trigger) a "one pulse" timer, using HAL library?
Thanks for the help.

 

I googled HAL timer and got these:

https://www.digikey.ca/en/maker/pro...r-interrupts/d08e6493cefa486fb1e79c43c0b08cc6

In a nutshell, use
HAL_TIM_Base_Init( ) to initialize the timer
HAL_TIM_Base_Start( ) to trigger the timer

Ask for more help if you can't get this working.
