AVR 中定義數(shù)據(jù)和命令輸入方法
[導(dǎo)讀]//CS=0 A0=0 寫數(shù)據(jù)口#define LcmWdataPort (*(volatile unsigned char *)0xFC00)//CS=0 A0=1 寫命令口#define LcmCmdPort(*(volatile unsigned char *)0xFE00) volatile unsigned char * 表示把后面的數(shù)據(jù)強(qiáng)制轉(zhuǎn)換為
//CS=0 A0=0 寫數(shù)據(jù)口
#define LcmWdataPort (*(volatile unsigned char *)0xFC00)
//CS=0 A0=1 寫命令口
#define LcmCmdPort(*(volatile unsigned char *)0xFE00)
volatile unsigned char * 表示把后面的數(shù)據(jù)強(qiáng)制轉(zhuǎn)換為指針類型
