i.MXRT1050 eLCDIF in RGB Mode on Custom Board

[PriyaMP]

Hi All,

I have used the SDK example evkmimxrt1050_elcdif_rgb example on my Custom Board which consists of - i.MRT1050.

PFA for the elcdif.c file

I then modified it based on the datasheet of AZ display - ATM0500D19-CT1 . PFA for the datasheet.

After the modifications, I'm able to debug. I was able to program the flash also.But the display seems to be blank.

The voltage of 18V reaches the LCD.

Is there anything that I should check to debug??

Hi，
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
After having a brief review of elcdif_rgb.c, I find the pixel clock frequency is too fast, please use the below code to replace the original code, then give it a try again.

CLOCK_SetDiv(kCLOCK_LcdifPreDiv, 2);
CLOCK_SetDiv(kCLOCK_LcdifDiv, 3);

Have a great day,
TIC
