Hi,

Please find attached image.

We are working on our own design with STM32F769NI and were success in running Touch GFX application.

1. But while running application we find lines are created at end of image. LCD configurations are 18-bit, DSI interface, capacitive touch, 240x320 Resolution.
2. At some time DSI commands are Timeout but works properly when reset performed.

Configuration changed done on STCUBEMX are

1. DSI changed to RGB666 format.
2. Resolution change to 240x320 in TouchGFXHAL.cpp and STM32TouchController.cpp Touchpad configuration to 240x320 along with read id commands change.

Could you please support us.

Looks like an off-by-one issue managing image width. Check if it is in the bitmaps or the paint process.​

Why you use RGB666 , TouchGFX can handle only 565 or 888 .
