Hi @sus-e,

As per this thread, the maximum SPI frequency is 3.5 MHz for a PIC32 and a 4 MHz for an AVR chip; anything faster than that will start to cause erratic behavior with the implemented state machine on the embedded PIC32MZ on the MTDS, especially if the touch screen functionality is being used.

Thanks,
JColvin
