用MSP430F149驱动不带中文字库12864液晶显示时钟
菜鸟做的一个用MSP430F149驱动不带中文字库12864液晶显示时钟程序。分别显示时、分、秒、毫秒。不过现在只能做秒表用用还行。用按键来调时间还没有做进去。呵呵主函数里的程序main.c
#include "io430.h"
#include "lcd.h"
#include "delay.h"
int main( void )
{
WDTCTL = WDTPW + WDTHOLD;
InitClock(); //初始化系统时钟
P4DIR=0xff; // 初始化IO
P4OUT=0xff;
P1DIR=0xff;
P1OUT=0xff;
P2DIR=0XFF;
P2OUT=0XFB;
RW=0; //LCD设置为写数据状态
RST=0; //LCD复位
delay_50ms(1);
RST=1; //LCD复位结束
Init_LCD(); //初始化液晶显示器
Initialization(); //初始化函数
CleanScreen(0X00); //清屏
uchar h1=0,h=0,t1=0,t=0,s1=0,s=0,ms1=0,ms=0,q=2;
while(1)
{ Shi_jian(3,4, h1,h,t1,t,s1,s,ms); //显示时、分、秒、毫秒
if(h1==q)
{ h=0;q=16; }
else if(q/h==4)
{ h1=0;h=0;t1=0;t=0;s1=0;s=0; }
else if(h==10)
{ h=0;h1++; }
else if(t1==6)
{ t1=0; h++; }
else if(t==10)
{t=0;t1++; }
else if(s1==6)
{ s1=0;t++; }
else if(s==10)
{s=0;s1++; }
// else if(ms1==10)
// {ms1=0; s++; }
else if(ms==10)
{ms=0;s++; }
else if(ms<=9)
{ delay_50ms(1362);ms++; } //延时1362为1秒
}
}

MSP430F149驱动不带中文字库12864液晶显示时钟ourdev_678553VUNGNT.rar(文件大小:330K) (原文件名:lcd1.rar) 不错，要做到精准是件难事。 想请教一下，如果你的12864是电源电压为5v的，其引脚可以和430直接相连吗？能把你的电路图发上来看看吗？ 回复【楼主位】fanhuamin1988
-----------------------------------------------------------------------
我本想用msp430驱动一块12864液晶，能够使它计时也能显示字幕。谢谢楼主，为我减轻了不少负担！！！ 回复【2楼】swordman000
-----------------------------------------------------------------------
430引脚是3.3V的。这个我也没有试过。怕是不行的吧！电路我是参照这个设计的。自己画的找不到了你可以参考一下

其背光可以用三极管控制
