Guest essele Posted October 15, 2011 Report Share Posted October 15, 2011 Hi, I'm just starting to experiment with connecting various LCD's to the Papilio ... I seem to be building up a collection of LCD's, my target application is around 3.8" and ideally sunlight readable, but I'll experiment with a range to build up some knowledge and experience. (Actually I've got my eyes on the DSi XL screen.) I thought I'd share my experiments as I'm sure other people will be doing similar things. So, my first experiment is with a 3.5" 320x240 (sunlight readable) from www.good-lcd.com, it's a GTT035HBHT1, the data sheet is here. They were very helpful while I was making my mind up and ordering, but unfortunately have gone completely quiet to my requests for SPI information (since there's no register info etc in the data sheet) ... anyway my hope is that it will just work with the RGB data ... time will tell. So this is phase 1 ... I put a breakout PCB together and had reasonable success soldering on a 50-way FFC connector... So first stage was just to fire up the backlight ... and that seems to work pretty well (although did highlight an open connection on my soldering)... So next stage is to get the papilio connected and generating a video signal, the timing information is in the data sheet, so I think this should just be a rework of my existing VGA code. Hopefully I'll make some more progress in the next couple of days ... I'll also knock up some more breakouts as I've got a really nice (and very low cost) Sharp LQ038J7DH52 to play with as well.
