STM32F407 software trigger a one pulse timer using HAL library

[Mbb.1]

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.

After having set up timer for the one-pulse mode (i.e. set TIMx_CR1.OPM), simply write 1 to TIMx_CR1.CEN.

I don't know if there's a Cube/HAL incantation for it; Cube/HAL is open source, you can look it up yourself.
