The "project" I'm doing is mostly about learning some new skills, it is a personal project that I'm doing on the side. It would be a handheld game console, mostly for GB or NES emulation.
So I guess a Raspberry Pi would be a better target, but... well, I rather like the idea of EOMA-68. My concept would be similar to the handheld ZEOMA console, but more reminiscent of the GameBoy. The benefit of using the EOMA-68 would be the ability to transfer your games between devices very easily.
Eh, maybe it's not the greatest idea. I could just use a raspberry pi and it would work mostly the same.
Thanks for the help anyway.

That's not RGB/TTL... that's parallel 8-bit. Different ball game. RGB/TTL is either 24-bit (8 bits per color) or 16 bit (6 bits red / 6 bits green / 4 bits blue -- blue is more intense to the human eye so it only *needs* four bits vs six for another color). The thing you're talking about... that gets talked to more like a character LCD than anything else. You know the display on those old HP laser printers you used in grade school? The ones that could *only* display text, and had a dedicated spot for each character...? *That's* a character LCD. *That's* the kind of interface you're looking at here.
Dude, if all you're driving is that kinda thing... use an Arduino. If you absolutely need Web connectivity (or if you need a little number-crunching ability but not a lot), use an ESP8266. On that note -- a friend of mine has found a way to turn off an ESP8266's WiFi side if you don't need it. (Info here. http://www.hackster.io/rayburne/esp8266-turn-off-wifi-reduce-current-big-time-1df8ae) If you somehow need something that's more than a fractional-horsepower driver for it ;) like if you're building some kinda fancy pants Johnny Five robot... throw a RasPi at it.
Here, this might provide some inspiration --> http://johan.kanflo.com/the-commadorable-64/ Despite the name, it's a daughterboard for a display like yours, that integrates an ESP8266 and driver circuitry. You'd have to buy the parts and solder it together -- and it's almost all surface mount stuff, mind you, which is a real pain in the tail... but it's worth it from what I can see here.
EOMA68 is *way* overpowered for any application using that kind of display. EOMA68 is on the level of a Dell desktop, or at least an older ASUS netbook.

Thanks for ask these replies! I'm pretty new to displays do this has been very informative. For the project in working on, I'll be using a smaller screen, maybe with a touch screen. Something like this:
http://m.ebay.com/itm/161863547262?_trkparms=aid=222007&algo=SIC.MBE&...
According to the page it accepts an 8-bit signal. From the looks of it, this would be able to directly use the RGB/TTL signal.
Another question I have is about SPI based displays. There seems to be a lot in this size range. Would those be able to display hardware accelerated video? Is that even a concern with this small of a display?

Well, then. I have been corrected.
Fun fact: all you need to hook an eDP display up to any computer with a DisplayPort output -- is a cable that adapts the connectors to each other. Someone on Hackaday did that a year or two ago. I thought it was neat then and I still do... don't think I bookmarked it tho. _______________________________________________ arm-netbook mailing list arm-netbook@lists.phcomp.co.uk http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to arm-netbook@files.phcomp.co.uk
