8段数码管编码问题这个函数什么意思

Question

unsigned char num[10][8] =
{
//a b c d e f g h 定义0-9的编码
{0, 0, 0, 0, 0, 0, 1, 1}, //0
{1, 0, 0, 1, 1, 1, 1, 1}, //1
{0, 0, 1, 0, 0, 1, 0, 1}, //2
{0, 0, 0, 0, 1, 1, 0, 1}, //3
{1, 0, 0, 1, 1, 0, 0, 1}, //4
{0, 1, 0, 0, 1, 0, 0, 1}, //5
{0, 1, 0, 0, 0, 0, 0, 1}, //6
{0, 0, 0, 1, 1, 1, 1, 1}, //7
{0, 0, 0, 0, 0, 0, 0, 1}, //8
{0, 0, 0, 0, 1, 0, 0, 1}, //9
};

8段数码管显示不同的数字就是对应不同的LED亮，你的这个代码应该是共阳的代码，输入0时LED亮，输入1时LED灭。比如0，需要显示a,b,c,d,e,f这6个LED，就是{0,0,0,0,0,0,1,1}
