Hej, I made a succesful first project and I am looking towards expanding the amount of hardware. Its a midi sequencer. I have been having a blast using the visual teensy to program the teensy from visual studio code.
I want to have something like 16 switches, 16 leds and 16 knobs.
Will this https://www.ti.com/store/ti/en/p/product/?p=CD74HC4067M96 multiplexer work for both receiving the input of 16 digital switches and analog knobs and sending output to 16 digital leds? Ive read all about how to loop over the channels of the multiplexer and letting some time pass before reading the signals. I understand that 16 channels might be a lot to loop over with so I am wondering if this would work at all. I need to loop over all this components all the time.
Will I need an extra capacitor somewhere in the multiplexer circuit or can I just do like in https://www.pjrc.com/teensy/td_midi.html many knobs example even though its a different multiplexer?
Should I use 3.3v pin in Teensy 3.6 or should I use the Vin (3.6v to 6v) pin? Datasheet says "HC Types 2V to 6V Operation High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V" So I guess the 3.3v should be fine?
Thanks for the help
