回答1：

液晶里面有字库么？要是不带字库的，我是觉得是没法显示的。
液晶不带字库的话，就自己写一个字库。

给你一个参考程序，你从中发掘发掘。缺少什么…
//OCM12864参考程序
#include

#define uint unsigned int
#define uchar unsigned char
#define disp_off 0x3e
#define disp_on 0x3f
#define disp_x 0xb8
#define disp_z 0xc0
#define disp_y 0x40
#define comm 0
#define dat 1
#define data_ora P1 //MCU P1<------> LCM

sbit di =P3^0; //Data or Instrument Select,H:写数据,L:写指令
sbit rw =P3^1; //Write or Read,H:read,L:write
sbit e =P3^2; //读写使能
sbit cs1=P3^3; //cs1=H,选择左半屏
sbit cs2=P3^4; //cs2=H,选择右半屏
sbit rst=P3^5; //Lcm reset,低有效
sbit bf =P1^7;
sbit res=P1^4;
