Robert,
Fantastic service - and whilst I wait for a few of the other components to arrive I've breadborded the 1284p as per this schematic
having downloaded the files from the site Arduino on ATmega1284P | maniacbug I can select the board in the drop down list, however when I come to upload the blink example I get the attached error.
I've tried swapping the TX / DX leads - no affect, different baud rates - no affect - on my FTDI board I get what seems to be a good comms as both TX and RX leds pulse, and shorting these wires results in an echo on the serial monitor, so the FTDI is working fine.
Anyone have any suggestions. I thought the transition from PIC to AVR / Ardunio was going to be a smooth one !
