Hello
I have a Innolux AT056TN04V6 display around from a 5.6in Photoframe. I had a look around and found its datasheet Box. Can anyone please tell me if this will work with a arduino or mega.
Thanks
This display requires drive signals (maybe similar to a TV) so you need to constantly drive it to display anything. You can drive it with arduino but you also need a display buffer in memory and the arduino memory is very limited. Unless you're very good at programming such thing as TV output and assembly, you don't want to do this.
I think I would first investigate if the photo frame itself might be hackable before trying to hook it up to an Arduino or any other MCU for that matter. If you can reuse parts or the whole photo frame controller in a way picframe.spritesserver.nl project did with st2205-based 1.5" key chain picture frame (sadly, only Google cache now remains of this project) , you may be able to get away with talking to the frame serially and letting the native electronics take care of the scanning/buffering. It needs 300K+ memory to address this display which is not available in Arduino without external chips.
Also, just physically connecting to these displays is a real pain. They always use the tiniest and the least standardized connectors the designer could find at the moment :~ So, if you can, again, reuse at least that part from the original frame, it would make working with it so much easier.
