Posted on March 22, 2015 at 02:49Hi,
Using the STM32429I DISCO demo board which has a 320x240 TFT LCD.
Running one of the demos in the STM32CubeF4, that uses the ''STemWin'' library to write a ''Hello World!'' message on the LCD.
By default the demo uses the SRAM and it has a bit depth of 32bpp (bits per pixel).
Is it possible to change the code to only use 8bpp?
If I change the driver from:
#define DISPLAY_DRIVER_0 GUIDRV_LIN_32
to:
#define DISPLAY_DRIVER_0 GUIDRV_LIN_8
the project compiles, but the screen looks weird, and I can't see Hello World anymore.
If I set it to:
#define DISPLAY_DRIVER_0 GUIDRV_LIN_16
I can kind see hello world 2 twice on the screen so there is some sort of width / height calculation issue, and not sure how to resolve it. Also I don't know if this is just a software thing, or if it would require a hardware change, like changing the lines going to the LCD?
I am new to development with an LCD so I am a bit lost. Any help appreciated.
