BuyDisplay ER TFTM050-3 with resistive touch connected to Teensy3.2 using MISO-MOSI-SCLK-CS
BuyDisplay said I need to connect also INT pin for touchscreen to work, done.
Tried with RA8875 library and examples by BuyDisplay as well with Sumotoy 0.79b11p10 RA8875 library/examples
I can get all graphic examples working but no touchscreen ones
Using Sumotoy's touchTest.ino i have random points appear in random times (later) when I tap touchscreen
so I assume resistive pad is working (it has continuity from panel ribbon to RA8875 pins).
I'm using 20cm stripline connection unshielded wires between Teensy and display
Any suggestion please ?
