Parallel LCD issue

Question asked by Rizwan Syed on May 19, 2017

Hi,

I am working on STM32F769BIT MCU. I have parallel 24 bit RGB data enable mode LCD Display.

I have generated a code from STM32 CUBE and changed the settings related to PIN,PORT configurations related to R[0-7],G[0-7],B[0-7], LTDC CLOCK,LCD_DATA_ENABLE pin etc.

 

Am getting a proper lcd clock ,data enable mode and data in other RGB pins when probed through CRO.

But unable to get data on LCD Display.It is just a blank white screen and Back light is ON. 

For Basic Testing, I am writing a RED colour data to LCD frame buffer but still unable to get data on LCD.

 

Is there any additional settings to be performed for Parallel LCD display in LTDC?

Please suggest

 

 

Thanks and Regards

Rizwan Syed
