Touch works on CYD, but not on ILI9431.  “Test Touch” sketch.  On CYD, opening screen invites to test, touch and the XYZ coordinates come up.  Not on the ILI9432.  The “TEST Touch”, flashes, then the XYZ displays.  However, no response after that.  “Serial Monitor”   then starts posting an error message, infinite loop, about the Y and Z sizes are smaller than zero.  Sorry, Sometimes the Arduino IDE is a pain.  It will not let me copy the errors.
