Unable to get the touchscreen to work #92

In case anyone else has this issue, I was unable to get any response from the touchscreen I am using Arduino IDE v2.2.1 on Linux

In the end I found that if I replace the line: SPIClass mySpi = SPIClass(VSPI); with: SPIClass mySpi = SPIClass(HSPI);

It resolved the issue :-)

Well isn't that interesting. I found just the opposite as I was trying to get the lgvl examples and demos running... The touch test uses SPIClass(VSPI). But the lgvl examples use SPIClass(HSPI). Until I changed that to SPIClass(VSPI), I got no touch response in the lgvl examples.
