Hi Ben,

Good news — the ST7796 display and XPT2046 touch are now working together over hardware SPI! Thank you for your suggestion about the SPI clock phase.

Here is a chronological summary of the investigation and successful test:

Initially, the display worked correctly with hardware SPI, but ...

In the Flowcode simulation, the touch areas assigned to the Display Manager objects work correctly. I have not verified the exact numerical X/Y values in simulation.

The problem occurs on the physical ESP32 hardware.

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

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 ...
