带字库型12864液晶的简单使用

/*=============================================
自定义汉字函数：CGRAM自定义显示字符
地址显示编码
0x400x0000
0x500x0002
0x600x0004
0x700x0006
共可显示四个自定义字符！
显示自定义字符前，先要设定显示的位置，否则会乱码
==============================================*/
void CGRAM()
{
uchar i;
write_LCD_command(0x30);//基本指令操作
write_LCD_command(0x40);//设定CGRAM字符的位置
for(i=0;i16;i++)
{
write_LCD_data(table1[0][i*2]);
write_LCD_data(table1[0][i*2+1]);//送显示数据到CGRAM区中
}

如果觉得我空间里面不够详细可以参看大海橡树的空间：http://hi.baidu.com/echoas（里面写的比较好）
