AVR实例教程_I2C读写24C04

//从24c04连续读出16个字节的程序 //读出数据通过led显示 #include<iom16v.h> #define uchar unsigned char #define uint unsigned int #include"i2c.h" uchar aa[16]; //短延时函数 void s_ms(unsigned int t) { unsigned int i ; for(;t>=1;t--) { } } //写一个字节 main() { uchar i; DDRD=0xff; PORTD=0XFF; i2c_init(); //初始化 i2c_rese(aa,0x00,16); //读出16个字节，起始地址0x00 for(i=0;i<16;i++) { PORTD=~aa[i]; s_ms(60000); s_ms(60000); s_ms(60000); s_ms(60000); s_ms(60000); s_ms(60000); s_ms(60000); s_ms(60000); s_ms(60000); s_ms(60000); s_ms(60000); s_ms(60000); } }
