Guys,
'1284 , IDE 1.0, maniacbug environment for pin definitions, optiboot hexfile bootloader.
What am I doing wrong here?
I power, LED on D0 flashes 4 times.
What I am I doing wrong here? IDE 1.0
I enter 00, I get back
"0207207
Invalid Relay Number 207"
according to asciitable.com, character '0' is 0x30, so why is the math not working?
arrg, software ...
