      1 // This sketch is to test the touch controller, nothing is displayed
      2 // on the TFT.  The TFT_eSPI library must be configured to suit your
      3 // pins used. Make sure both the touch chip select and the TFT chip
      4 // select are correctly defined to avoid SPI bus contention.
      5 
      6 // Make sure you have defined a pin for the touch controller chip
      7 // select line in the user setup file or you will see "no member"
      8 // compile errors for the touch functions!

     10 // It is a support and diagnostic sketch for the TFT_eSPI library:
     11 // https://github.com/Bodmer/TFT_eSPI
     12 
     13 // The "raw" (unprocessed) touch sensor outputs are sent to the
     14 // serial port. Touching the screen should show changes to the x, y
     15 // and z values. x and y are raw ADC readings, not pixel coordinates.
