How do I increase MCPWM frequency beyond 1MHz?

Postby hientv1999 » Fri Jul 23, 2021 7:05 am

The MCPWM module of ESP32 by default has tick clock at 1MHz which means the highest frequency I can achieve is 500KHz. I tried and verified that it cannot output any signal above this 500KHz frequency. After searching Google for a day, I understand that why can modifier some register value or make our own driver file for MCPWM. However, I don't know where to start. Can anyone please give me a hint? Thank you
