Downloaded and installed in the arduino-0021/libraries folder, then read dumpmonBlink.pde into the IDE and get this when I compile
dumpmonBlink.cpp:4:57: error: dumpmon.h: No such file or directory
dumpmonBlink.cpp: In function 'void setup()':
dumpmonBlink:9: error: 'dumpmonSetup' was not declared in this scope
dumpmonBlink.cpp: In function 'void loop()':
dumpmonBlink:13: error: 'dumpmonLoop' was not declared in this scope
I don't normally use the IDE so don't know what to tweak.
