用MSP430G2553单片机控制Ht1621的程序及笔记8页.doc

型号：HT1621BS725G01012液晶全部显示时如下图：6位数字、3个小数点和右方电源标志全部点亮函数：/*全部点亮*/ void HT1621_all_on(uchar num) uchar i; uchar addr=0; for(i=0;inum;i+) Write_1621(addr,0xff); addr+=2; 屏幕数字笔画对应编码：程序例子：#include msp430g2553.h#define uint unsigned int#define uchar unsigned char/*定义1621的端口*/#define DATA1 P2OUT|=BIT0/1621DATA端口#define DATA0 P2OUT&=BIT0#define WR1 P2OUT|=BIT1/1621WR0端口#define WR0
