I am working on interfacing both the NHD-7.0-800480EF-ASXN and the NHD-5.0-800480TF-ATXL to a PIC32MZ DA microcontroller.  I am using the PIC onboard graphics controller and have been able to successfully display images on the NHD-7.0.  It seems it would be a relatively simple process to make the NHD-5.0 work on the same interface with a few small timing adjustments, but I cannot get anything recognizable to display on it.  Only a some noisy grayscale garbage.  Is there a significant difference between the two that I am overlooking.  I have played with the timing quite a lot with no success. 

Hope someone here has an idea. 

Thanks,

Josh

Hi Josh,

Try changing the pixel clock polarity for the 5" TFT to see if that resolves this issue.

Best Regards,
