Hello,
I am using STM32F769BIT6 processor along with 7inch orient LCD 800*480. i am trying to port STEMWIN lib on it. since the LCD is interfaced in RGB, i am using lin driver.
1. i used GUIDRV_LIN_16 & GUICC_M565, i can draw pixel by pixel in 200*480 active region for layer0. I am also using FMC based external 256Mb SDRAM for Frame buffer.
the problem is when i am increasing the X axis more than 200, the drawn image is shaking and i am not able to make out what is drawn, pixels are scattered.
2. when i use GUIDRV_LIN_24 / 32 & GUICC_M888 / GUICC_M8888, i am not able to draw anything.
can anybody help what could be the issue as i am not doubting the LTDC controller config for LCD as when i jus set internal flash as frame buffer i could see full 800*480 image without any STEMWIN.
i am attaching my files, kindly suggest me where could be the issue.
thanks
sanjeev
