In touchgfx_how to config GT9271 CTP driver with custom stm32h753BI- experts help needed

[jr_engr_mbed]

Hi team,

I have interfaced LTDC and TouchGFX, and they are running without any problems. My CTP driver is GT9271. How do I configure this with the H753 custom board?

I found a video on YouTube

Adding External Flash (QSPI) and touchscreen driver to custom board - WARNING: BORING VIDEO ;) - YouTube

that goes through the process using the BSP of discovery boards where his CTP is similar to the discovery board. However, I noticed that the H743I-EVAL BSP uses a different driver.

What steps should I take to achieve the exact output? Please guide me as we are almost ready with the UI.

Thank you.

Best regards,

Hello @jr_engr_mbed,

TouchGFX uses similar methods to communicate with a touch controller connected to I²C, therefore, the MCU or display interface does not matter. Here you can find an explanation on how to set up the touch controller, and how to report the touch event to TouchGFX.

Please take a look at them, and let me know if you have more questions.

Best regards,
