I found that -10 gave a good display contrast so you may need to have some adjustment range. Craig,

Thanks! Just a couple questions on power supply for people who have got it working. Are these the right values? Vdd=5V Vss=GND From specs Vdd-Vo = 22.2V typical, so that means : Vo = -(22.2V-5V) = -17.2V and Vdd-Vee = 26V (max) so Vee(max) = -(26V-5V) = -21V So I was going to use Vee at approx -19V and connect a trim pot between Vee,Vo,Vss and control Vo to approx -17.2V Hello, just received this module.

I'll try to get some display happening using an Altera FPGA and possibly an 18F4550 PIC. Thanks for the LCD, nobody seems to have gotten one working yet though!

If I get one, I plan on putting it in the top of my xbox case on a mechanical push switch to pop it up and display information from the UnleashX dashboard.

But probobly a PIC18F will have a slow refresh rate, but theres still dsPIC This display shure looks useful especialy at that resolution.
