Thread: Teensy 3.6 I2S (DAC + ADC boards possible?)

    Teensy 3.6 I2S (DAC + ADC boards possible?)


    I have a Teensy 3.6 and would like to use the I2S pins to plug two separate ADC and a DAC boards simultaneously. I know there is only one I2s port available in the T3.6. But, since my ADC board has its own clock and to my understanding only needs the DIN connection, I wonder if I could still plug a parallel DAC board to the DOUT pin in slave mode, using the clock of the T3.6 or maybe even better that of the the ADC board.

    Is this possible? How would the general setup of connections look like? I know that MCLK, LRCLK and BCLCK are all fundamental but I don't how to wire them, if possible for both ADC and DAC to coexist.

    Thanks in advance for the guidance,

    We can't answer how to wire the boards if you don't say which...
    But yes, it's possible - there some threads in this forum about it. Perhaps a google search helps?
