AX206 - Problem with "pale" display

Hello

I have hacked my display AX206 with fw_disp_delightdigi_black.bin (tried with fw_devel_delightdigi_black.bin too)
but I have got problem with "pale" display

No.1 is oryginal, no.2 is hacked.

How can I set contrast ?? Backlight seems to be ok, brightness too.

Setting of contrast is currently not supported by dpf-ax. Working on it.
If you upload a dump of the original fw, I will have a look...

New version of delightdigi_black committed to svn.

Dpf-ax currently has a flaw - lcd contrast is not initialized by default. Most lcds will work without it - but some need it. The only solution atm is to find the contrast-init routine in the original dump and add a it to lcdinit.s. I'm currently working at a more generic approach that will work with (hopefully) all displays ootb and will allow user adjustable contrast. First step is the screen testpattern, so you can find the optimal contrast (already done). Next step is the implementation of the contrast setting code (work in progress).
