stm32单片机的定时器资源相当丰富，它的定时器分为高级控制定时器、通用定时器和基本定时器，具体这些定时器资源在哪个系列的片子有就得看不同的片子的手册了。他们具体有什么区别，我也是刚接触这个，看他的数据手册介绍也是茫然，主要是刚开始摸 ...

This works nicely. I can switch mit power electronics with 60kHz while I get ADC interrupts at 30kHz. Now inside the ADC interrupt i write the new ePWM duty cycles back to the ePWM's shadow register.
