Pour ce projet il vous faudra:
-une plaque 1088AS
Pour le code il vous suffit de copier de le code et le coller dans l'IDE.Le code est ci dessous:
#define Max7219_pinCLK 10
#define Max7219_pinCS 11
#define Max7219_pinDIN 12
void setup() {
pinMode(Max7219_pinCLK,OUTPUT);
pinMode(Max7219_pinCS,OUTPUT);
pinMode(Max7219_pinDIN,OUTPUT);
delay(50); //Initialiser
Init_MAX7219();
}
void loop() {
