I added these to the WProgram.h, which gave another error:
D:\arduino-1.01\arduino-1.0.1-windows (1)\arduino-1.0.1\libraries\TinyDebugKnockBang/TinyDebugKnockBang.h:156: error: 'DEC' was not declared in this scope
So I added #include "print.h" in the WProgram.h , and now it compiles and uploads.
When I open the serial monitor (19200 baud) and type a ! I get this error:
--- Knock-Bang fault: 15 ---
I was thinking it maybe had something to do with the clock speed which was 128kHz, so I tried at 9,6 mHz and got this error:
--- Knock-Bang fault: 11 ---
i get the correct respons from the serial monitor, when I use @,# and !
