If you have 8 analog input sensors (or 2 or 9 or 738479) is there a chip / is it possible with microprocessor programming to actively monitor all of the channels? Say you had 8 rotary potentiometers attached to each i/o pin on the mux, would you have to change the selection inputs every time you wanted to use a different potentiometer? It seems like this would make a mux much less useful than I thought it was. So if I wanted to use the pot on i/o pin 1 and then the pot on i/o pin 8 immediately following the first, I would have to tell the microcontroller / processor to change to reading pin 8 before I could use the peripheral attached to it? Or is there a way to make it monitor all of the i/o pins at once so that I could use the peripheral on pin 1 then on pin 7 then on pin 2 without having to do anything at all regarding changing the io pin being read, so long as I only use one at a time?
CD74HC4051MM96EP is the mux I already have tons of, and I'm using teensyduino (arduino code library) / teensy 3.1 to send midi messages. I'd like to read all kinds of different input sensors.
