Raspberry Pi Python GPIO Quick start guide
Introduction
Raspberry gPIo
Wiring Pi
Blink
#include <wiringPi.h> int main (void) { wiringPiSetup () ; pinMode (0, OUTPUT) ; for (;;) { digitalWrite (0, HIGH) ; delay (500) ; digitalWrite (0, LOW) ; delay (500) ; } return 0 ; }
To compile and run:
gcc -Wall -o blink blink.c -lwiringPi sudo ./blink
