C examples

gpiolib.c is a simple library to manage the gpio via sysfs in C.

Output example

#define GPIO_IN  1
#define GPIO_OUT 0

gpioexport(80);
gpiosetdir(80,GPIO_OUT);
for (;;) {
    gpiosetbits(80);
    gpioclearbits(80);
}

Input example

#define GPIO_IN  1
#define GPIO_OUT 0

gpioexport(80);
for (;;) {
    printf("%d\n",gpiogetbits(84));
}

The gpiolib.c library is available on Github.
