Excellent! > then you can just run > make sketch.cpp > make VARIANT=ellduino You should also be able to do just "make", and it should (try) to build the four possibilities: - ellduino hardware - stm32f4discovery hardware - ellduino emulator - stm32f4discovery emulator The first three should work, the last one fails as we currently have only an assembler version of the STM32F407 startup code. (Rewriting that in C should be trivial, given that we already have the STM32F050 startup code in C, and the STM32F407 startup code in assembler. If someone wants to try, please feel bold and go ahead. :-) You should also be able to "make clean" and it should remove everything it built, but sketch.cpp. "make clobber" should remove everything "make clean" removes, and then remove sketch.cpp. I'm afraid there may be a bug or two in "make clean" so that it doesn't remove everything. --Pekka
