MSP430單片機的實時時鐘及溫度顯示程序

ID:395176 · 發(fā)表于 2019-4-14 09:23

最近學(xué)習(xí)MSP430,把以前學(xué)習(xí)的DS1302和DB18B20移植過來了，把時序搞清楚還是比較簡單的，溫度顯示做得比較粗糙，分享一下（PS:后續(xù)有時間添加按鍵設(shè)置及其他功能

）

單片機源程序如下:

uchar index=0,T500MSfg=0,flash=0;
uchar psec=0xaa;
uchar time[8],str[12];
//uchar second=10,minute=20,hour=11;
/*

{
LcdMove[16+i]=str1[i];

{

}
}
