TouchGfx Touch

[Sanjay27]

Hello,
I am using the STM32U5G9ZJTXQ with TouchGFX on a 4.3-inch display (480×272). The display works fine, but the touch is not working. The touch controller IC is GT911.

Hello @Sanjay27.

Could you please share the content of your STM32TouchController.cpp file?

E.g. the TBS for the STM32H745I Discovery Kit available in TouchGFX Designer also uses the GT911, so you can use this as a reference. Alternatively, you can also have a look at this repository: https://github.com/STMicroelectronics/stm32-gt911.

Best regards,
Johan
