640 x 200 LCD,

[joshua17ss2]

i recently got a large lcd display, its 640 by 200, I havent got a clue on how to drive it, i have got micrcontrollers, basic stamp and im gettting a cubloc soon, i was wondering if anyone has code for these EG64E00BCWU. i can drive the LCD, the -19 volts for LCD drivings alittle complicated, can i just use a resistor to know down a 24 volt supply, and use it backworks so its negative ?
i would love to find some commented code thats easy to modify.
im semi fluient in basic,.
josh
thanks

I had just a short look on the datasheet and it seems to me maybe you'll need a more powerful microcontroller or FPGA. Depends what do you want to do with it.
I had a look some time ago at the nice LCD display that www.sparfun.com sells - the same as in the PSP but I did not buy one yet as I am lazy to develop an interface to connect it to a FPGA board (which I have). I am not sure BASIC is a good idea, perhaps Assember or C would be better.
Unfortunately I don't have your display so I cannot help you with coding, I am working just with 16x2 alphanumeric LCDs

Ive been working alot withthe 18F4550 series microcontrollers. i like them because of the nice easy USB interface, there should be more then enought power to run this i hope, might have to add on ram.
The whole coding for multiplexing always comfused me. isnt it more or less coding in bianary for the display.
i can always just hook it up find some code for a smaller pixel driven screen and try to expand it for the size i got

thanks josh

What sort of connectors does your GLCD have? I looked it up and the controller may or may not come with it. Can you post its datasheet?

 

[joshua17ss2]

FLM- display cycle start marker, CL1 display data latch, CL2 display data shift, M control signal for ac driving, VEE lcd driving power, VDD, VSS, VO operating voltage for LCD driving, D0-D3, display data

Sounds a little odd, do you have a data sheet? M is unusual, so is only a 4bit bus (most GLCDs are 8bits wide)

**broken link removed** This is the data sheet ive been reading thought, i think that i have read it correctly, im still learning how to properly read data sheets.
thanks
