ARDUINO 8個8*8的矩陣組成大跑馬燈
我有8个MAX7219 一个MEGA2560 8个8*8矩阵打算组成4*2的排列 变成一个大的跑马灯 求大神指点怎麼接法才能用~
可以的話順便幫我打個程式吧~
下面是简单的demounsigned char i;
unsigned char j;

#define count 6 //级联个数
int Max7219_pinCLK = 10;
int Max7219_pinCS = 9;
int Max7219_pinDIN = 8;

} 我會接一個的呀 但是我不會接多個的@@ 第一个的输出端接第二个的输入端以此类推
可以跟我講哪一腳接哪一腳嗎 我是新手 聽不太懂@@ 哪隻腳有輸出呀@@
