12 one time pulse timer ?

[OYoru.1]

Hello !

I need to create 12 (separately triggered pulse trains for thristors) one time pulse timers. (one pulse train consists of approx 10 pulses with approx 10us wide) Many stm32s only have 2 or 3 timers with RCR ( one pulse timer with repetition counter). Do you have any suggestions ? What can i do ?

Thank you

I plan to make many pwm channels and make a counter which will increase or decrease in pwm timer interrups (like a software repetition counter) and finally stop pwm channel.

but even with that i need min 12 separate timers, i think i cant use other channels in same timer?

But there are many masters here => like waclawek.jan

Maybe there can a better and simple way
