I've been trying to get this demo board to work but no success. Is there a way you can have a look at the two links below and let me know if there is any way you can help me out. Any help would be appreciate it. Is there a driver needed for the demo board at all?
    Have to agree with Jerson, it could be that the PIC has been wiped and needs re-programming (with the sample code at the end of the PDF). The demo board has the ISCP pins to allow you to connect to a PIC programmer in order to do this.

    Basically it looks like the demo board was simply designed to allow you to test various LCD screens. Plug in an LCD, hook up to a USB port for power and the company info would by default scroll across the screen.. You could then modify the code, compile it and then reload it so it says something completely different. - no "drivers" are needed (Windows running on a PIC.... now there's an worrying thought )

    Do you have the ability to program PICs ?

    Red face re: getting lcd to work

    hi again.. thanks so much for your response. I actually hooked everything up and connected the usb to my pc. the lcd powered up and started displaying the company welcome notes. Then I downloaded turbo C/C++ from the net for windows 7 64bit, and wrote the exact same code into the program and just changed the welcome message to my own. But after compiling the program i saw no results. It just kept on displaying the company info. I took some c++ programing for a semester back in college but that's about it. If you can help me program my pic i would greatly appreciate it. thank you

    Wink regarding my lcd display and demo board

    hi again.. thanks for your reply.. I actually hooked everything up together and pluged the demo board by its usb connection to my pc. It started displaying company information. but when i used the exact same programing codes that came with the demo board in Turbo C/C++ win 7 64bit, i didn't get any results of my own. I just changed the greeting message to one of my own. nothing changed. Im not sure if its the turbo c im using is the right program or it could be the code. not sure.. help me out please. i will provide you with any information you that is necessary. thank you.
