Found this, it's not documentation, but it's working code, at least...

https://github.com/facchinm/kernel-brain/tree/master/drivers/hdmi

 

edit: got it. Though it's in the open web, the document is confidential, so I won't upload, just paste the link I found.

Oh, that datasheet doesn't have the programmers model. You will need these documents, that I didn't find, but maybe they can be found:

 

SiI-PR-1032 Transmitter Programming Interface (TPI) Programmer’s Reference

SiI-PR-0020 SiI9020 HDMI PanelLink Transmitter Programmer’s Reference

SiI-PR-0041 CEC Programming Interface (CPI) Programmer’s Reference

And I thought this was going to be a joke.

 

This one in fact.

 

The Jedi Master Yoda, took delivery of a new 4K resolution TV. To test it out he, of course, watched his favourite film.

When it came to the scene in which Yoda himself starred, he declared:

 

"Ah! ... in HDMI"

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
