For my sins, I disconnected my current project from the arduino board, and fitted a small pcb with a plug-in 328, as I thought I had finished programming. Of course now I can't see whats going on with the serial monitor.
One of the projects has shown up a strange problem, but of course I have no ISP lead, ( and I didnt put a socket on the board )
Looking at the circuit http://brittonkerin.com/annotateduino/annotatable_duemilanove.html
it looks like the only connections between the FT232 and the chip, are the tx rx and reset pins.
So as I have nothing connected to these pins on my embedded chip ( apart from the reset pullup 12k ) it seems that I should be able to run 5 wires from the embedded chips tx rx reset, gnd and 5v, to the pins on my empty arduino board, and be able to see whats going on.
Has anyone done this?
