I have a simple Arduino sketch that spans several files. There is a function signature in an h file, and the definition in the C file.
If I attempt to compile ("Verify") the sketch, I get "undefined reference" errors to the function defined in a C file. Changing the file name from *.c to *.cpp resolves the issue, but I don't want to define the file as a C++ file. Is it possible to compile plain old C files in Arduino?
Thanks in advance.
The Arduino IDE is very limited, my advice: avoid it. You have some alternatives you can find here: http://arduino.cc/playground/Main/DevelopmentTools
