TouchGFX with parallel LCD and external SDRAM for frame buffer

[phil2nice]

Hello all,  

i am looking for a solution for Parallel LCD with framebuffer in external sdram (using fmc) and capacitive touch with GT 911 on I2C

is Touch GFX ready for that configuration ?

i am kind of lost reading LVGL docs and touch GFX docs 

thank for help to start choosing

Hello @phil2nice,

As said here Solved: GT911 Display Controller: Hardware + Firmware Need... - STMicroelectronics Community this is a I2C peripheral, so if you have the driver and the configuration this will work.

There should be no problems with that configuration.

Parallel LCD is the easiest interface to get started with.

You can explore the Board setup for for example STM32F746G discovery kit supplied with TouchGFX. This uses FMC RAM and parallel LCD.

The board setup for STM32U5G9J-DK2 uses the GT911 controller in an efficient manner.
