How to identify HSPI as default SPI?

Postby Bwanna » Fri Aug 04, 2023 7:28 pm

I have an ESP32-WROOM trying to use the XPT2046_TOUCHSCREEN library by Paul S.

His library uses the default SPI pinout which I believe is automatically set to VSPI. I have a setup where the XPT2046 is wired to the HSPI pins on the ESP32.

How can I select HSPI to be the default SPI seen by Paul's Library?

The touchscreen library will accept an SPIClass object in begin, so set up hspi as in https://github.com/espressif/arduino-es ... _Buses.ino, and pass that object as a parameter in the begin for the touchscreen.
