Bonjour
j'ai besoin d'aide concernant ce programme...je veux le traduire en langage C, merci d'avance.
The Shell script to blink the LED is given as follows
// Blink an LED on breadboard
//PIN="26" # P8_6is gpio1_3 = (32 * 1) + 3 = 35
GPIOPIN="/sys/class/gpio/gpio$PIN"
if [ -d "$GPIOPIN" ]; then
echo "Blinking LED connected to Pin $PIN ..."
else
echo $PIN> /sys/class/gpio/export
echo "Blinking LED connected to Pin $PIN ..."
sleep 1
fi
while true; do
echo high> $GPIOPIN/direction
sleep 2
echo low> $GPIOPIN/direction
sleep 2
done
 fclose(duty);
 fclose(period);
 fclose(run);
 return 0;
}
