bit()
Description
Calcule la valeur numérique d'un bit spécifié (bit 0 vaut 1, bit 1 vaut 2, bit 2 vaut 4, etc.).
Syntaxe
bit(n)
Paramètres
- n: le rang du bit dont il faut calculer la valeur, en commençant à 0 pour le bit de poids faible (le plus à droite)
Valeurs Renvoyées
- La valeur calculée du bit
Exemple
void setup() {
Serial.begin(9600); // opens serial port, sets data rate to 9600 bps
long x;
for (int n = 0; n < 16; n++) {
x = bit(n); // equivalent to x = 1 << n;
Serial.println(x, BIN);
}
}
void loop() {
}
The result in Serial Monitor:
8
Serial.println("Hello World!");
