SAADC channel and PPI

Hello,

I an using a PWM and sampling 2 ADCs in scan mode. I want to read the output of the PWM as an ADC, kind of like a feedback. Is it possible using PPI.

Thanks

  • Hi,

    No this isn't possible. The ADC doesn't use the GPIO peripheral when it samples, it instead uses the analog pins, and there isn't possible to interconnect them internally with PPI as the analog pin doesn't support it. You could always interconnect them externally though.  You can also synchronize the SAADC with the PWM by using PPI, but that isn't quite what you're asking for Slight smile .
