//实验目的：熟悉12864LCD的使用

//12864LCD带中文字库

//编程让12864LCD显示公司LOGO和公司名字

//硬件设置：

//关断所有拨码开关。


 #include             //dsPIC30F6014标准头文件


  _FOSC(CSW_FSCM_OFF & XT_PLL4);  //4倍频晶振，Failsafe 时钟关闭

  _FWDT(WDT_OFF);                 //关闭看门狗定时器

  _FBORPOR(PBOR_OFF & MCLR_EN);   //掉电复位禁止，MCLR复位使能。

  _FGS(CODE_PROT_OFF);            //代码保护禁止


#define  di  LATBbits.LATB4       //命令/数据选择              

#define  rw  LATBbits.LATB5       //读/写选择

#define  e   LATBbits.LATB6       //使能

#define  psb LATBbits.LATB2       //8位/4位并口选择

#define  rst LATBbits.LATB7       //复位
