So i have this board for converting CGA signals to VGA, but the problem is it doesn't work because of bad firmware.
I have 1 working board, and about 100 non working ones. (I'm not joking here.) I contact the people who sold them to me, and ask for assistance, they basically tell me no, or "Oh, We sell you bad board? Send back, we give you new one!"
I'm getting at my whits end. I have the data sheets, the firmware, ext. But I cant read or rip the data from the chips.
I can wire it up write the sketches, EXT, but there I2C protocol does not follow the arduino standards.
I asked on the SA reverse enganerring forum, and they say i have everythign i need. But the arduino wont seem to coperate. Nor can i find the addresses its asking for.
Iv tried using my minipro tl866 to program it, no dice.
It seems like someone has tried to do this before, but that was about 2 years ago and the thread has since died.
So I'm hoping my arduino can help me. But if I do a i2c scan for addresses, nothing shows up.
Ask me for anything you need. I'm good at programming, but this is going a bit beyond my scope. And from what I can tell, there is ALOT of people who want a sketch that can do this.
TLDR; Help ;-;
