  • Programming Troubles

    Hello everyone,
    I've recently ordered a PICASO-GFX2 uLCD-32PT(GFX) for a school project, and I'm having some issues with programming it.I have the screen connected to a serial port via a MAX232 chip, and the computer in question is running Windows XP via VMWare. I think I have all the proper connections, but I am unable to find a schematic to ensure that the screen is connected to the MAX232 correctly.When I try to download a program, I get the following error:"Device is not responding. Please check your configuration.Do you have an SGC PmmC loaded by mistake?"I have confirmed that I have a GFX PmmC loaded, as visible on the splash screen.
    Can someone tell me what I'm doing wrong?
    Thank you

    There is a circuit in the FAQ section that shows you how to use a MAX232 http://4d.websitetoolbox.com/post?id=4664334

      I had an opportunity to try this circuit today, and I continue to get the same errors.

        My apologies, I missed a connection. It seems to be working now.

        Thank you
