    Yeah i love my LCDs.. after a bit of tinkering and finally noticing the plastic cover was still on it is REALLY clear and i can't wait to mount it somewhere and start using it properly.

    At the moment we are all using LCD Studio so any recommendations like Malcs said would be great.

    Here's some things to keep in mind for everyone attaching lcds to parallel port: http://lcdproc.sourceforge.net/docs/stable-0-4-4-user-html/x904.html

    As I mentioned earlier in this thread I've noticed few times with a CFAG12864-TMI-V that the chips have been getting hot when I've plugged it in. It has been fixed by just unplugging it and plugging in again. Maybe the latchup situation mentioned there ?

    I believe it happened few times with my Displaytech KS0108 display too. I don't remember this happening with any other controllers than KS0108 and it has become a habit for me to check that the chips aren't getting hot everytime I plug in a KS0108 display. Maybe the parallel port pins can be in a state which KS0108 doesn't like.

    Well i've rebooted my PC. And still nothing on the display.... :wallbash:

    Going to check my wiring tonight. Does anybody know off the top of there head. Which wires could be wrong? It all lights up, and the contrast works, just nothing happening.... :jawdrop:

    Sorry, Stuart, it looks like it's been lost in the post, i'm quite annoyed at the post office now, i'm gussing that about 10% of the kits i've sent has been lost, i think i have the recipt, I'll try and dig it out, see if i can make a claim or anything, give me another day or two on it, then i'll sort out a resolution with you and jay.


    crystalfontz, I have deffo not reversed the polarity here.

    Measured my p-port output voltage, nice and stable at around 3.3v.

    My test PSU (which i believe was at fault) was outputing 5.21v, could the .21v increase be to blame?

    Also I noticed the display get progrssively more flickery, as if the refresh-rate for the whole display was gradually decreasing, could this be an indication of an instability in my powersupply (which i can't detect with my meter) or just a sign of the chip(s) getting too hot?

    Thanks for your help,

    im new to wiring these lcd's so one question!

    what do i do with the GND , and the 5v wires?

    could i basically join the ends of all the GND wires up with solder or one single wire? and also the 5v do i just join them also to the 5v? thanks

    Right.. here is what i did.. for the GND's on the parallel connector i linked all of the GND pins up with solder and then ran a bit of solder over the edge of the plug so it was touching the outside metal of the plug.. this will ground it.

    For the LCD i just took all of the GND cables and crimped all 4 into the black (Ground) molex plug.. and all the 5+ i crimped into the yellow (5 volt) pin of the molex.

    Acrim,

    Whenever I use my test PSU to power my little 5.6" color LCD sitting here, I get dark lines rolling on the screen. The speed of the scrolling depends on what colors / brightness is being used on the display. My display is fine with the dodgy voltage put out by my test PSU, but I'm going to say that it is your power supply's fault. When I'm running my LCD on my test PSU, the chips are cold.

    Hope I helped,
    -TX297

    Right, I just wired mine up, and got the LCD Studio software installed. I have installed the correct driver, and to a point, the display is working :D

    If I set up a screen with the time and date on it, I can only see them if they are on the right-hand side of the display !! It appears the left side is blank :worried:

    Anyone got any ideas ?? Off to check and recheck wiring.

    Darkside.

    anybody got liquid mp3 working? it gives me dodgy display with pixels missing and its all stretched :( lcdinfo was the same but the creator sent me an update which works fine. but still lcd studio is the best so far, even tho liquid mp3 has better mp3 plugins.

    also anybody got the weather plugin working for lcdstudio


    thanks

    Rechecked wiring, and I had CS1 wired to pin 15 on the parallel port instead of pin 16. All working fine now :clap: :clap:

    Thanks got to Visualaid for making this possible for everyone :rock: :rock:

    Darkside.
