It there a way to adjust vcom by code or by hand on s3 board?

The s3 board seems could adjust vcom automaticlly depend on screen model, so you don't need to adjust the variable resistance by hand, it's really cool, and i tested it can adjust vcom of 060XCD
, 060XCH
and give them a perfect painting result (in v5 board you must adjust vcom).
But on 060XD4
, 40% of the screen can be rendered perfectly, the other 60%
, the screen will be lighter the expected.

You can adjust it using what you can see in the demos:
https://github.com/vroland/epdiy/blob/main/examples/dragon/main/main.c#L38
epd_set_vcom(1560); // That will be -1.5V
But on 060XD4, 40% of the screen can be rendered perfectly, the other 60%, the screen will be lighter the expected.
I really do not think that this a VCOM related issue.
