Hey,just updated my site with some new stuff including my modding of a nokia 3310 LCD and a homemade Vector game! Follow on into the forum if you want to discuss things, let me know what you think. I love hearing feedback from people. www.pyrofersprojects.comps, no more 1541-III-dtv for now..

Hmm.. Been seeing some action with Nokia stuff for Propeller lately too.. I imagine ebay (old phones) being the best source for cheap Nokia screens. What phones should I be looking for? Or is there a better source?

You can get the 3310,3330,3390 screen for a few pounds, maybe 5 euro or less. The colour screen i used is also cheap that is in 6100, 6610, 7210, 7250. Also, if you want to use the propeller for something cool, try this lcd www.sparkfun.com/commerce/product_info.php?products_id=8335It needs a lot of power to run it, but the prop should do.

Just thought id update. I got nice character mapped graphics going on the Nokia LCD now. Im writing a boulderdash clone, its a right pain with the 8pin pic! so little rom and ram...
Anyway, if people need help getting the colour 6610 or b&w 3310 screen running give me a shout. Id appreciate any thoughts people have on my projects!
Im also making a Power over Ethernet PIC device.

Got a pretty much playable boulderdash clone going on with an 8pin pic and 3310lcd. There is only one input pin so requires a resistor network over the buttons (old trick) to use the single pin and a2d for input. I have scrolling screen, large maps, multiple levels, falling rocks/gems, working exit, collectable gems, 3 lives and titlescreen etc. The rocks/gems have different graphics for falling/still. No pin for sound but i could waste the mclr pin (eek) for that if i wanted.
Its a nice single chip handheld game, runs from cr2032 battery as well.

Pyrofer, what's your new LCD? It's pretty, and fast. How are you talking to it? I2C?

If you mean the new Colour one its a parallel display from a HK site, I assume its a phone screen but im not using SPI so its much quicker. Its a nice 128x160 display, and quite cheap.

Can you provide a source for it? Sounds cool. I want to do a little LCD display hacking myself.

I can provide the init code and basic routines for both 3310 and 6100 displays. Ill try to remember to get around to posting them, but if you email me at mail at pyrofersprojects you should get a quicker response

Oh, thanks!
I actually meant a source for buying the parallel control lcd setup you're describing. I appreciate the offer of the source CODE though. That's great.
I'm still a ways off from actually being able to drive an LCD from a microcontroller, but that's the direction that the parade is headed for me. I'm still learning my basic circuit analysis and understanding the analog circuitry dynamics to enable all the programmery stuff. Digital logic is my stock and trade at a higher level, but the analog stuff has confounded me for most of my life and I'm putting a stop that THAT first. ;-)

Start with the Nokia 3310 LCD, easy to get on ebay. Just solder the wires on the back to the SPI port on the PIC and a few control lines. Run the whole thing at 3.3v (use an lf pic) and your done! Its so easy its silly. Meant to say too, for the parallel screen try... www.techtoys.com.hk/Youll see me linked on his homepage They have lots of nice screens, you can even get a 320x240 one!

I've been looking for a cheap source of 3310 displays. I can't seem to find it inexpensively right now. eBay sources all seem to be $20USD-ish shipped. I did, however, order this: www.bgmicro.com/index.asp?PageAction=VIEWPROD&ProdID=10816with data sheet here: docs.bgmicro.com/pdf/lcd1030.pdfIt's cheap ($10!) and 128x64 versus the 3310's 84x48 pixels. It has a parallel interface and its own on-board frame buffer RAM. It seemed like a good one to experiment with, though I'll see what I find when I get it. I ahve an unused ATmega8L here, and a handful of 8051 compatible uC's and a couple PIC's as well. I've only used the AVR chips before, so it's ALL learning here... ;-) I'm still on the look out for a 3310 or two. I want to eventually add one to my 1541-III-DTV.

That LCD looks like a very common type. Youll probably find lots of info on using it. I will assure you though, I dont think youll find an easier display than the 3310. Its got like 8 wires on it, and 3 or 4 of them are power related. You can ignore the reset and chip enable lines, meaning you need just about a clock and data from the pic!
