The problem occurs on the physical ESP32 hardware.

Please let me know if you need any further tests on the E32R40T hardware ...

XPT2046 wrong coordinates using shared hardware SPI on ESP32

Hello,

I am experiencing a problem with the XPT2046 touch controller when using hardware SPI in Flowcode 11.

Hardware

- LCDWiki E32R40T
- ESP32-32E
- Display controller: ST7796S
- Touch controller: XPT2046
- Display resolution: 320 x 480

The display and touch controller share the same SPI bus ...
