14 [相关定义]
15 1.需要在事件在单片机引脚定义文件中添加以下引脚定义：
16 //LCD控制信号寄存器
17 #define T6963_COMMAND_REG P4 //DB0-7口
18 //LCD数据端口寄存器
19 #define T6963_WRITE_CODE_REG P5 //控制口0-4,依次为WR、RD、CE、CD、RST
20 #define T6963_WRITE_DATA_REG P5
21 #define T6963_READ_STATE_REG P5
22 #define T6963_READ_DATA_REG P5
23 2.需在工程中包含"SC_T6963.c"文件
24 3.需在主程序文件中加入：
25 #include "inc\SC_T6963.h" //LCD相关
26 **************************************************************************/
27 #include "inc\ConstDef.h" //硬件相关常数定义
28 #include "inc\SC_T6963.h"
