What kind of LCD do you have that has 24 pins? Is this one of those 7-segment types?
You should look into the whole Nokia-knock-off LCDs (check www.sparkfun.com). Easy to control, 6 lines from the PIC, 130x130 pixels, and in color. I'm having a blast with mine.
the LCD im using is the seven segment type. it had 3 digits and two decimal points. there is 24-pins (one common, 3digits*7segments is 21 pins, and then the two decimal points. im using a 4x20 serial LCD for debugging and showing lots of info, but i would like to have this on top just to show small amounts of info. these things were pretty cheap, so i thought i would try it. and the datasheet shows the pinout but thats about it. they dont have current of voltage ratings, so i tried it on the breadboard and it seems to work at 5V and my meter doesnt show any current. it also seems as though it will "light" up all the way down to .5V (maybe lower but thats as far as i tried). so im thinking i might be getting inductance or a little leakage off of the flux on the traces that are beside each other.

i was thinking about the nokia lcd, and i would like it, but i wanted to keep this really small and simple. i havent looked at what it takes for code space either.. is it the same as a parallel LCD?? my little 3 digit one takes lots just because i need to tell it to turn on different ports.

im working on a flight data recorder for my rc airplanes, and i know there are some out there that i could buy for cheaper than i can make (i already have one too), but i would like to make my own. i will try to post a pic when i get home tonight..
