    Hi all

    I'm building a midi project that samples approx. 20 analogue signals and I need to do it as fast as possible. I'm wondering would it be faster to use 1 CD74HC4067 to multiplexer 10 channels...

    Thanks Defragster

    That did the trick, but I had to apply the same for the "get" command to receive the correct values from the EEPROM otherwise I got rubbish.

    O defragster, you little beauty and I'm a muppet. COM port changed to COM14...........pfff.

    It seems that after I program the Teensy, it automatically changes COM port, seems bizarre to me.

    Hi

    Would this be a correct assumption:

    ADC Clock Teensy 3.2 = 400Khz

    1 / 400Khz = 2.5uS
    So the ADC can sample a sensor value every 2.5uS.

    ADC0 needs to sample 11 sensors before sending...
