I'm thinking if you use the UISP programmer with the STK500 board for AVR programming, you may have run into this already (I hope!!) I've been programming AVR devices with good success using uisp from unix (macOSX flavour) and using the STK500 with no problems. Unfortunately, I made the mistake of briefly using a PC with AVR-Studio on it, and it re-programmed my STK500 with updated fir...

Hello, Since the Atmel STK500 is much cheaper in the US than in Europe (79USD in the US, around 120EUR in Europa are the prices I found) I'd need a recommendation for a good webshop in the US.

Hi all, I was just trying to use an STK500 AVR development board. My version of AVR studio told me I should upgrade its firmware.

No other LEDs light up, and I cannot talk to the board via AVRStudio. I need to get this board running ASAP. Is it possib...

It seems to me that from a hardware perspec...

I see some activity on the serial port with a scope, but nothing coming back.

The cables I'm using to connect master and slave are some "ran...
