Hello,

I am using MKM35z512vlq7 microcontroller . I need to configure 3 adc chanel one for pot,2 temp sensor and 3 for current sense by using sw trigger . I need to read 3rd and 2nd channel in continuous mode .Can you tell me the approach how can i do this so that my all adc work properly and can not conflit with each other.

need your support as soon as possible.

The KM35 only has 1 ADC module, so all the channels need to have the same clock configuration, because of this one option is that you read 2 channels on continuous mode and then reconfigure the ADC to read using trigger mode. the problem is that if you need good accuracy on the ADC measurements you will need to calibrate every time that you reconfigure the ADC, I do not know if this is an option for you
