Вот прикупил у братцев наших... китайцев вот такую штуку... пришел мне конструктор =) пришлось доставать с полки паяльную станцию (опыт то не пропьешь ) вот даташит на MAX7219 Чувствую будет у меня много вопросов с адресами Кроме демо надыбал вот этот код Код (Text): #include "LedControl.h" // нужна данная библиотека LedControl lc=LedControl(12,11,10); // подключенные пины // pin 12 подключен к DIN // pin 11 подключен CLK // pin 10 подключен CS void setup() { // the zero refers to the MAX7219 number, it is zero for 1 chip lc.shutdown(0,false);// выключите энергосбережения, вкл. дисплей lc.setIntensity(0,1);// Устанавливаем яркость (0~15 возможные значения) lc.clearDisplay(0);// очистить экран } void loop() { for (int row=0; row<8; row++) { for (int col=0; col<8; col++) { lc.setLed(0,col,row,true); // включается светодиод столбец, строка delay(10); lc.setLed(0,col,row,false); // выключается светодиод столбец, строка delay(10); } } } Ждите скоро будет много вопросов =)))))
