How to connect different display to mimx1064EVK board

[shahmanishj]

Rocktech display works with some changes on LVGL_DEMO_WIDGETS sample example. We are trying to connect a different display with 640x480 display. I looked at the file - lvgl_support.c where clocks are configured in DEMO_InitLcdClock(). But, I am not sure how the constants are used for PLL, dividers etc. Can someone help here to explain?

Hi @shahmanishj ,

  You can refer to this application note:

https://www.nxp.com.cn/docs/en/application-note/AN12302.pdf

  When you use the new LCD, you need to check your LCD datasheet, find the related data:

Then modify the code.

I recommend you test the LCD code at first in the SDK, eg:

SDK_2_11_1_EVK-MIMXRT1064\boards\evkmimxrt1064\driver_examples\elcdif

After the LCD works, then you can add to other LCD related project.

Wish it helps you!

Best Regards,
