MSP430FR2355: TIDA 010056 Trapezoidal code ADC

Raj

Hello I want to add ADC of measure current in TIDA trapezoidal code. I know I should add given MEASURE_IDC macro but not know the proper way to use another ADC in code. Can anyone pls suggest way how can I use speed and current adc both? I tried adding MEASURE_IDC and conversion enable macro in timer interrupt after measure speed macro but not getting proper adc value. Please suggest proper way to add different ADC in given code.

Hi Raj,

I think this design should already measure the current:

Thanks!

Hello John I know this diagram. I am asking how to use another ADC like current,BEMF in given TIDA 010056 Trapezoidal code. I want to know configuration of another MEASURE_IDC adc macro to use it in code? I wanted to know in code implementation.

Hi Raj,

Like this?

This code is set ADC in single channel mode, and chaneg the channel to capture other channel voltage.

If you would like to use other channel, you can refer this example code:
