아두이노 빌드 프로세스 & c/cpp

c/cpp 지원함

Can I program the Arduino board in C? 

In fact, you already are; the Arduino language is merely a set of C/C++ functions that can be called from your code. Your sketch undergoes minor changes (e.g. automatic generation of function prototypes) and then is passed directly to a C/C++ compiler (avr-g++). All standard C and C++ constructs supported by avr-g++ should work in Arduino. For more details, see the page on the Arduino build process.

아두이노 켜면 뜨는 sketch 파일은 바로 빌드 되는게 아니라 여러 단계를 거쳐서 빌드 됨

일단 소스를 보면.. 기본골격이 setup() / loop() 인데

아마도... 이런 구조로 변환하려나?

#include "board.h" #include "wiring.h" #define F_CPU 16000000 extern void setup(); extern void loop(); int main() { setup(); while(1) { // main loop loop(); // event handler - not interrupt serial_event(); } }
