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?
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.
