WiringOP-Zero

WiringPi / WiringOP libary for the Orange Pi Zero with 26 pin GPIO header

This is a modified WiringPi for specially OrangePi Zero.

GPIO and SPI working, i2c not testet yet!

To control red LED on the board run for example this:

gpio write 30 1 

and to turn off this

gpio write 30 0 

Small test program: Blink

Create a file called blink.c with the content:

#include <stdio.h>
#include <wiringPi.h>
int main (void)
{
wiringPiSetup ();
pinMode (30, OUTPUT);
printf ("Test program is running.\n");
printf ("Status LED is flashing.\n");
printf ("Press CTRL+C to stop programm.\n");
for (;;)
{
digitalWrite (30, HIGH);
delay (500);
digitalWrite (30, LOW);
delay (500);
}
return 0;
}

Then to compile and run, you would enter below in the command line:

gcc -Wall -o blink blink.c -lwiringPi
sudo ./blink

Thanks to zhaolei & xpertsavenue, who created the libary for this one!
