I'm currently developing on ATtiny84A and begin to find very difficult to continue without a proper debugger.
So I've bought the AVR JTAG ICE and make my research and find that if I want to enable debugging (debugWire mode) on that chip,
I would have to enable the fuse DWEN which one disable the SPI port (that I need for a peripheral).
My question is : Is there any solutions to debug my chip keeping the SPI port UP ?
Thank's in advance.
