Hello to all!
I have a problem with the STK500, it seem not work..
This morning i tried to test my spi driver using loopback technique. So i have connected the MOSI pin with the MISO pin (respectively PB3 and PB4 using ATmega328p).
After that, the AVR Studio (ver. 6.2) has ceased to connect with the STK500.
I tried to connect the STK500 using my old pc and the original serial cable. In this pc i have installed the AVR Studio 4, but nothing..
In the previous program that i put in the microcontroller, i tested the usart connection, and this worked well with Matlab. After the loopback pin connection, I tried again to use this program, but the serial connection between matlab and the STK500 It does not work anymore.
Where is the problem?
Please, anyone can help me?
