• Hi !

    To increase the number of available pins on the Espruino Wifi ofr a current project, I wish to share the I2C & SPI bus for several peripherals:

    On the I2C side:

    • OLED screen ( addr 0x3C )
    • Color sensor ( addr 0x29 )
      On the SPI side:
    • APA102
    • SDCARD

    I had a quick thnk on 'may-be solutions', but I'd be glad receiving further advices before not knowingly messing around

    The following drawing is for the SPI side of things, but I wonder if fiddling with the I2C CLK would lead to same behavior ?

    Thanks in advance :)
