16x32 P10廣告屏點(diǎn)陣任意位置畫(huà)點(diǎn)畫(huà)線，點(diǎn)陣直接用P10單紅門(mén)頭廣告屏，省去了自己焊接，刷了一個(gè)時(shí)鐘走時(shí)程序，圖片中間點(diǎn)是秒閃,
用的是12c5a60s2。

單片機(jī)源程序如下:

sbit STCP=P2^4;       // 鎖存時(shí)鐘
sbit DATA=P2^5;    // 數(shù)據(jù)輸出
sbit OE = P2^0;          // 使能輸出

uchar PLAYBUF[64];
uchar a,b;

uchar sec=0,min=0,timecount=0;
