I have successfully flashed the AVR, and the display shows which station is playing.
But the router does not receive tuner commands from the AVR. When I launch interface.sh, the script does not echo "Tuner Position: 0", and changing the tuner position does not have any effect.
When I had it all connected on the breadboard it worked fine, so my guess is that it is a bad connection somewhere. But I have tried to:
* resolder the RX on the router twice.
* checked that the ADC4 port on the ATmega receives correct voltage according to tuner position.
* flashed the AVR again, and ran make fuse
* reinstalled interface.sh, and display2.sh
I`m out of ideas. Any help?
