Hi everyone,

i try to get the STPC to work on a TFT display under WinCE 4.2. I'm right at the beginning and tried a little bit around with a LC24.2 Trend Display. The problem is, that the only resultion, which works is 640x400x16. At any other resolution i got only a black screen or 'hacked' pictures. So is there any specific, which should be set in Windows CE registry (e.g. monitortype) or some reference TFT display which works flawlessly with STPC Atlas?

Hi everybody,

nobody could help, so i had to help myself and i found it out!! The problem is that the standard ddi_stpc only support two kinds of TFT. These are PhilipsHLD1201 and LGPhilipsLM151X2. Both have there ROM settings stored in tftdata.c. All i had to do was playing around with these values (0x0f set polarity control is the BIG switch which decides if your display shows anything or not) and i got a nearly perfect picture (little colour failure with a single gray scale). So far it goes on.

Best regards,
