The Protocentral ADS1220 has 4 analog input channels. I want to be able to hook up 3 different signals to 3 of these analog input channels, and then use Arduino to record measurements from these 3 different signals sequentially (measurement from channel 1, measurement from channel 2, measurement from channel 3, measurement from channel 1, etc).
The library just has one function used to read data, and I'm not sure how you can get readings from the different channels.
