I've got a 800x600 LCD panel with no controller that's currently just sitting under my desk, I wonder if I could get an Arduino to drive that. I've got a full manual for it that includes all the timing info. hmmm....
If it has the standard 18-20 connections for communication, it might work.

Nope. 31. It's an NEC NL6448BC20-08 - See page 7 for pin connections[^] It's got full input signal timing information in the manual, so surely I should be able to figure out how to drive it even if the standard libraries don't support it. (It's 640x480, not 800x600 as I originally said)

It seems that has an RGB input. From what I can see 6 bit's per color. #1 Arduino does not have that many pins, you might have better luck using an I/O expander like MCP23x1x series or a shift register. #2 Due to large screen size, it might be hard for the Arduino to keep up filling that huge space. #3 You need a 25Mhz clock, not possible on Arduino... :( Would be cool to get something going, look at some low res TV/VGA circuits.

Yeah, I had thought I might be able to use some kind of serial to parallel converter and drive each 6 bit rgb from a single pin.

That's where I buy a second unit to handle driving the screen, and just handoff drawing commands to it.

Doh. Hadn't noticed that. Sounds like it's getting out of my depth. Back to flashing LEDs.

I've seen some nifty PAL/NTSC tv drivers for Ardunio, I'll probably end up looking into them if I need my remote controlled sharks to have visual output.

Welcome to the world of uControllers. I've had mine for a while now and love it. There are plenty of tuts and projects to be had by googling. If your just starting out you may want to check out this article on my site to set up programming environment[^]. It says for the ATMega1280 buts it applies to most boards. Good luck and enjoy, Mike

Here[^] is another very inexpensive development platform based on the TI MSP430 family - only $4.30 for the hardware and the development software can be downloaded for free from the Texas Instruments website. The board includes an on-board flash emulation tool which makes software development a snap...

I love the arduino. This weekend I got a grill, and thought: I could use a temperature sensor. The ideas didn't stop there. I started thinking about the advantage of having multiple sensors in the grill, and using a display for the output. If you like to cook, this could be a fun project. Enjoy

Thanks for mentioning the programming environment web page. I didn't know about these other tools. Sincerely, Mike

Mike, Glad it helped. Mike

I don't know what to DO for a project, but for platform I gotta Chameleon: http://www.xgamestation.com/view_product.php?id=51[^] An AVR -and- a Propeller on one board with all support circuitry including plenty of memory.

Nice, a lot of horse power..Have you done anything with it? Mike

Fraid not. It comes with a TON of demo projects to try. But as cool as that thing is, my priority is http://pianocheater.com[^] And I can't seem to justify any free time away from it for doin uC stuff :(( Well, technically, :-D I like my lil sequencer:thumbsup:

Nice app I can see why you don't have any free time. I've found that the uC does take a lot of time and the learning curve can be steep, depending on what you expect to get out of it. Mike

It IS a pretty cool app (biased a little) :rolleyes: The AVR doesn't have tooo much of a learning curve if ya know C already. Well, ok, the timer,"somewhat remote" flash memory for data,interrupts... That propeller is wierd. It's "spin" language is a wierd combination of basic and c++ or SOMEthin. Has 8 threads (processes?) running INSTEAD of interrupts. Anyways, my project is gonna be a 4 legged robot. google "issy done yet" or somethin. I forget the link... Buuuut, that won't be for about 2 years I'm guessin:)

If it's This one?[^] that's a pretty ambitious project.

Yeah I was reading about it in the first link you had and it's definitely a different animal than the AVR line. The software is pretty easy, I've done Assembler, C and C++ pretty extensively over the years (been a while so have to refresh) and the electronics (some experience but many years so more than a refresh), making the PC boards, the mechanics, etc.. Just a lot of different areas of expertise that even though I'm a pretty hands on guy it is a lot to absorb. Plus I'm older and have CRS (Can't remember s&^t) so makes it challenging. But over all it's worth the effort. Don't know as I'll ever do the walking robot thing but went to the flea market a couple of weeks ago and got an RC car without remote for $2 and had a board hooked into it and chasing the cat around the living room by days end. (I love to torment the cat, he gets his revenge) Mike

Yeah, that's the one. Not the full scale thing tho. Probably just 2 ax-12+ servos per leg. Side to side and up/down fixed 90 degree legs. You can buy em seperately from the full scale robot kit. (again, i forget the name of the kit - robot magazine will find it gREAT magazine) Arbotix controller (which has an avr+zigbe wifi) No top half like he added with the lazer,sight stuff. Soooomethin like that. We'll seeee...
