I am using the stand alone Arduino IDE to build some projects, and I have a few
.cpp files now, but during work I renamed them
.c and back. When compiling the project now (with Ctrl-R), it is still trying to compile the
.c files. But, I don't even see them on disk!
.cpp makes no difference. I am used to IDEs having some kind of project file, or a "clean project" option, but I cannot find those here.
