I want to use SAR ADC to detect the PWM, how should I configure the ADC.Do you have example?
Break zero reply
you can find several ADC examples here MPC5 software example list
If you need to synchronize ADC sampling with PWM you can refer to MPC5643L PWM_ADC measurement concept GSH614
How to determine the sampling frequency of SARADC?
could you specify the MCU you have?
read chapter 40.5.11 "Conversion Time" of the device RM; https://www.nxp.com/docs/en/reference-manual/MPC5775KRM.pdf
Thank you very much,but I have a question,What is the difference between ADC_CTR0 and ADC_CTR1?
