I write a program for Teensy 2.0 in ANSI C, but I can only compile it if the file extension is
.ino. Having in mind that pure C is valid C++ syntax why I get compilation errors for almost every single line of code?
[env:teensy20] platform = teensy framework = arduino board = teensy20 build_flags = -D USB_MIDI
Am I missing something in the configuration of the project? By the way I have included the arduino library header
#include <Arduino.h> on top of the program.
