Connecting to the Uzebox

[azurewraith]

Never mind, checked my RCA connections on your note that the LCD TV may not be syncing correctly, and I was not getting any sound because the video was not getting to the source input. Guess the back of the TV was hard to see... o_O

Thanks for your help, breathing a sigh of relief and playing some Megatris ^_^

Hmm, guess I just matched the colors, red to red and white to white. Whoops.

Haha good one! I'll have to add this to the troubleshooting wiki!

It's Mark from the first post again. Finally got my 5v adapter and I'm still trying to connect to the powered AVCore. For an unrelated reason I'm running a freshly installed WinXP32. I've installed the drivers for my programmer and the Device Manager claims it's working. Maybe I'm doing something wrong in AVRStudio.. I'm using the stk500 platform and com 3. I've tried some other platforms but they usually just stop me from selecting the correct atmega chip.

Here's my setup--

AVCore Module - http://www.sparkfun.com/commerce/produc ... ts_id=9024
Olimex AVR-ISP500 - http://www.olimex.com/dev/avr-isp500.html

I've uploaded some screen captures of errors and such--

I've tried changing around the ISP frequency but that doesn't seem to make any difference. Any ideas?

Mark -

I'm just stepping out, so I haven't looked at any of your images, but I recall a bug where AVRStudio would only work with com 1. They may have fixed this, but if they haven't or you're using an older version, that would be a good place to start.

I always recommend buying Atmels own AVRISP MkII to avoid such hassles. Anyhow, the Olimex devices appears to use an FTDI chip with the virtual COM port driver. From your screen shots, the virtual COM port speed settings seems wrong. The STK500 protocol specifies the serial setting must be: 115.2kbps, 8 data bits, 1stop bits, no parity. After that insure the ISP frequency in AVR Studio is set low enough (1/4 the speed of the target AVR device). Let us know if that works.

I switched it to COM 1 and changed the speed settings but I still get the same errors. I have the ISP speed set to 57.60 kHz in AVRStudio, the lowest possible since it needs to be above 5 kHz to work.
