Hi Team,

Do we have APP note like https://www.ti.com/lit/an/snla132g/snla132g.pdf?ts=1649940059664&ref_url=https%253A%252F%252Fwww.ti.com%252Fsitesearch%252Fen-us%252Fdocs%252Funiversalsearch.tsp%253FlangPref%253Den-US%2526searchTerm%253DSNLA132%2526nr%253D39

I saw the code example, but I'm not sure the detailed comments. If we want to set frame rate = 60, which part should we need to modify?

Regards,

Roy

Hello Roy,

I would suggest to use ALP to help generate these PATGEN configs. ALP has a tab for PATGEN in the latest version which allows you to graphically enter your desired config and generate the reg output

Best Regards,

Casey

Hi Casey,

Yes, I'm trying to use ALP to see the difference, but I'm not sure why the register is setting like this.

Regards,

Roy

Roy,

The frame rate is set by the total number of lines per frame, and the line period:

Line Period = 1/(FPD*Lines)

Example:

Total lines = 480 + 33 + 10 + 2 = 525

FPS = 30

Line Period = 63.49us

Best Regards,

Casey
