8x8矩陣顯示器實習-跑跑小藍人 材料: Arduino uno x1 8x8矩陣顯示模組(內含max7219) 接線方式: 圖片來源於:https://create.arduino.cc/projecthub/CiferTech/8x8-led-matrix-tutorial-project-code-and-schematic-969e60 觀念 速記 控制顯示器的閘門主要是max7219,在一開始時先設定好max7219 的暫存器的設定值,包含了{顯示強度, 顯示檢測, 解碼, 停機, 掃描 限制,不運作},運送資料的方式類似寄送mail,首先要有郵址,該信件 傳送到該擁有者,開啓信件觀看到內容.所以傳送資料的方式是先 把SS設定為0,CLK時脈計算同步時間,MOSI,MISO傳送資料的收發. 程式碼 #include <SPI.h> const byte actionLed[8][8]={ {0x00,0x8b,0xef,0x3c,0x18,0xa0,0xc0,0x00}, //1 {0x00,0xdb,0x6f,0x3c,0x18,0x28,0xd0,0x00}, //2 {0x10,0x4b,0x5f,0x3c,0x28,0x48,0xd0,0x00}, //3 {0x53,0x4f,0x3c,0x18,0x28,0x48,0x90,0x00}, //4 {0x93,0x8f,0xfc,0x38,0x28,0x50,0xe0,0x00}, //5 {0x93,0xcf,0x3c,0x38,0x48,0xd0,0x20,0x00}, //6 {0x03,0x5f,0xbc,0x78,0xc8,0x30,0x00,0x00}, //7 {0x00,0x03,0x0f,0x7c,0x58,0xe0,0x00,0x00} //8 }; //定義max7219暫存器 const byte NOOP=0x0; const byte DECODEMODE=0X9; const byte INTENSITY=0xA; const byte SCANLIMIT=0xB; const byte SHUTDOWN=0xC; const byte DISPLAYTEST=0xF; //max7219函
