// This sketch is to test the touch controller, nothing is displayed
// on the TFT.  The TFT_eSPI library must be configured to suit your
// pins used. Make sure both the touch chip select and the TFT chip
// select are correctly defined to avoid SPI bus contention.

// Make sure you have defined a pin for the touch controller chip
// select line in the user setup file or you will see "no member"
// compile errors for the touch functions!

// It is a support and diagnostic sketch for the TFT_eSPI library:
// https://github.com/Bodmer/TFT_eSPI

// The "raw" (unprocessed) touch sensor outputs are sent to the
// serial port. Touching the screen should show changes to the x, y
// and z values. x and y are raw ADC readings, not pixel coordinates.
