    Hi, im wondering how to handle spi when chips have diffrent max clock speeds.

    should i change clock speed between communicating with different chips?
    Or should i use two buses with diffrent...

    SPI pins teensy 4.1

    I'm using a teensy 4.1, and got some questions about SPI:

    Is it possible to use both "miso,mosi,sck,cs" (pins: 12,11,13,10) and "miso1,mosi1,sck1,cs1" (pins: 1,26,27,0) at the same time?...
