hi,
Since couple of years ago,I've had a custom board using STM32f429 uc . And god bless ST company for nowadays good linux-based IDEs and HAL Cube libraries.
For the instance,I customized a LTDC example of Cube v1.24 lib,STM324x9I_EVAL (SW4STM32 IDE), for my own board to drive a color LCD 7",and it successfully showed the RGB565_480x272 bitmap picture in source code,since I'd chanegd configurations with every details of ltdc protocol for my Board and LCD.
(Configs like LTDC gpio pins,clock,etc and Hsync,Vsync,VBP,HBP,etc for LCD).
for the next step,I made a CubeMX template for my board and generated a code for AC6 (SW4STM32) IDE with exactly the same Cube Library as customized STM324x9I_EVAL... and copied the routines to newly generated code with CubeMX to use STEmwin middleware...
All the Gpio ,clock,ltdc ,etc and routins checked to be the same as previously cusomized code.but...strangely, the LCD shows only mixed color bar codes instead of thorough bitmap picture.and even can't change background color as well.
So,is there any advice except that configs I mentioned to be considered for this nightmare?
