ADV7611 Setup script help

Hi,

   Kindly note that, Video formats with TMDS rates below 25M pixels/sec require pixel repetition in order to be transmitted over the TMDS
link.

   When the ADV7611 receives this type of video format, it discards repeated pixel data automatically, based on the pixel repetition
field available in the AVI InfoFrame Since the pixel clock for the 480×272 resolution is below 25 MHz..

    Please refer '6-1d' script configuration for '24-Bit SDR 4:4:4' Mode.

Thanks,

Sorry for the late reply. 

I took a look at the 6-1d script configuration but it does seem like it uses the YCrCb format as an output instead of RGB, but I think i might be wrong. Should I just test it once I get to that part later in my project, or do I need to make some modifications to the script for it to work?

I think it may be important to mention that I am using two ADV7611's, one for each screen, but they are on different I2C lanes so i don't think thats an issue but idk

         Yes, the register configuration needs to be done based on the input and output requirements. The register descriptions are available in the ADV7611 Reference Manual and the Software Manual.

        Then it's fine, The second chip needs a different set of 7 I2C map addresses so the 2 don't collide when they are on the same bus.

Okay. I'll go through the 6-1d script and use the reference manual to change all references from YCrCb to RGB, i guess.
