Re: Qu'est-ce qui te bloque?

bonjour
voila ce que j'ai essayé:
int main()
{
int p; char tab[max_N];
int gpio = 26;
p=open("/sys/class/gpio/export", O_WRONLY);
sprintf(tab, "%d", gpio);
write(p, tab, strlen(tab));
close(p);
sprintf(tab, "/sys/class/gpio/gpio%d/direction", gpio);
p = open(tab, O_WRONLY);
write(p, "out", 1);
write(p, "in", 3);
close(p);
if [ -d "$GPIOPIN" ] then
fprintf ("Blinking LED connected to Pin $PIN ...")
else
// echo $PIN > /sys/class/gpio/export

fprintf("Blinking LED connected to Pin $PIN ...")
//sleep 1
else
while (true) do
{
sprintf(tab, "/sys/class/gpio/gpio%d/value", gpio);
p = open(tab, O_WRONLY);
write(p, "1", 1);

write(p, "0", 1);
close(p);
return 0;
}
