MSP430FR2355 ADC Channel

Dear all

I am using MSP430FR2355, I want to get ADC data from  3 different channel for example A3,A6,A7.

I could get ADC data separately from each channels, using change ADCINCH_XX in sample codes for each channels. I read reference  (Ref User Guide (SLAU445I) Sec 21.2.7.2) and another question in support chat, I know that should use timer for it but I don’t know how to use it.

I have question:

1. I want  to get data from different channel one after other ( for example first A6, then A7 and finally A3).could you please let me know how to do it in my attach code?
2. Also is it possible to get data from 3 different channel at the same time? If yes, could you please help me for it?

I look forward for your replay.

Best Regards

Hadi
