How to write data directly to TFT LCD Screen Buffer Generated by TouchGFX?

Hello Everyone,

I'm using the STM32F429I-DISC1 Development Board, I'm new to TouchGFX and I'm trying to control the TFT LCD on the Board directly with code. I have created a basic screen with black background and printed "Hello, World!!" in the center of the screen. Now I want to write data directly to the screen buffer created by TouchGFX and control individual pixels using code. Is this possible to do? I'd appreciate any help.

Thanks in Advance.

Figure where the frame buffer is, and use a pointer ?
