    When I went to "Config Memory", some of the addresses were not there, like 300001, 300003, 300005, 300009, 30000B, 30000D. Also, when changing the value, am I right in assuming that CH424 just listed the last 2 digits of the hexidecimal value? I.E., the value for 300000 comes up as 0x3fff, would I change that to 0x3f20? Thanks for any help.
    I built the programmer based on the Olimex design (JDM? ), which seemed to work well. WinPic detected it and wrote the code to the PIC, but I want to make sure I made the right settings for the memory config and to make sure I wasn't missing something since some weren't showing up.

    One~Zero, I actually have no idea I'm afraid. Just look at the screenshot I posted. Edit: does the circuit actually work or not?

    iiibadboyiii I'll have a look....

    Edit: email re-sent Rene.

    No worries, it was my fault :blush:
    I didn't load the .dev package for the 18F2550. Came up just like your screenshot (more or less). Said it wrote to the IC fine, just need to build up the rest of the circuit to test. Thanks.

    I have a LCD, but it is wired up as SPI so I have 4 wires to hook up (power,ground,data,clock). Is the firmware modifiable for SPI?

    acidice333, no I'm afraid not. If you want to do that, you might as well start from scratch - what are you using at the moment?

    One~Zero, glad you got it sorted... remember to post pics!

    Edit: willyf1, who are you talking about?

    I'm using a HD44780 display, with a daughter board converting it into a SPI connection. It is connected to a PIC18F4550, and just displays text. I can go back to connecting all the pins of the HD44780 but I would perfer fewer wires.

    Nevermind about me wanting the firmware source, I have made my own code for the SPI wiring (2 wires to the PIC) and most of the commands are working.

    Brilliant acidice333 - I sent it anyway, if you're interested.

    Warrior_Rocker, thanks for the heads up! Looks pretty cool, especially as he didn't use USB hardware!
