GPIO Output Switching Frequency Limit

Our application requires more PWM than what the Apalis iMX6 can offer. To cater for other function, in this case display backlight control, we tried to use GPIO to simulate PWM but the frequency was limited to 100Hz. May I know if it’s possible for us to go any higher than this and how?

hi @jerry.lee

Could you provide the version of the hardware and software of your module? Which carrier board are you using?

May I know, how did you simulate the PWM? Which SODIMM?
