// PIO SPI allows high SPI clock rates to be used when the processor is over-clocked.
// PIO SPI is "write only" and the TFT_eSPI touch functions are not supported.
// A touch screen could be used with a third party library on different SPI pins.

// This invokes the PIO based SPI interface for the RP2040 processor.
