HI TI
I'm trying to find if the connection is ok from UB941 TO LCD，How to make the UB928 display the color bar image output by UB941 which configured with internal clock and timing in Pattern mode ？

Hi Alex,
I was able to generate the registers using Analog LaunchPAD (ALP). I am assuming that you already have this software downloaded but if not I highly recommend using it to configure the registers. ALP can be downloaded off the TI website.
First, I opened ALP and chose the 941AS as my device. Second, I went to Pattern Generator tab. Third, I selected Colors Bars, changed the timing source to internal, and then changed the spec to HD 1080p 60 Hz (yours might be different if you are using HD 1080p 30 Hz). Lastly, I hit apply.
By clicking on the registers tab it allows me to see what the values of all the registers should be to generate the color bars pattern. In the registers tab if you click display it will provide you with a register dump.
If you have any trouble getting the register values let me know if you need me to provide a register dump or script.
Best regards,
Anthony
