nec码红外遥控完整编码

红外遥控编码程序如下:

NEC .SECTION 'DATA'

a_REM_CODE DB ? ;KEY DATA CODE

a_CUSTOMER_1 DB ? ;遥控器头码(客户码)低八位

a_CUSTOMER_2 DB ? ;遥控器头码(客户码)高八位

#define CUS_6221_1 00110100b ;1234H

#define CUS_6221_2 00010010b ;@------------------------------------------------

NEC_CODE .SECTION 'CODE'

;@************* SUBROUTINE[xx]: Send Remote Code ************

;;遥控码发送:

SEND_REMOTE_CODE:

clr WDT ;清除进位标志，检测遥控发送的有效的按

键

SZ fg_SendActive ;SZ表示以0结尾的字符串

JMP READY_SEND ;跳转到READY_SEND模块

ret

READY_SEND:

NEC_CODE:

mov A,a_KEY_NUM ;将数值发送到寄存器A中，直接寻址

mov M_TBLP,A

TABRDL a_REM_CODE ;查表专用指令

;读取遥控头码(客户码)低八位数值 MOV A,CUS_6221_1

MOV a_CUSTOMER_1,A

MOV A,CUS_6221_2

MOV a_CUSTOMER_2,A

以上为READY_SEND运行模块，同时是为后面NEC码发送的准备;首先将一个按键的数值已以直接寻址方式发送到寄存器A中，将寄存器A的是发送到M_TBLP中，然后查表a_REM_CODE，将CUS_6221_1的值发送到寄存器中，在赋值给遥控器头码(客户码)低八位a_CUSTOMER_1，同理，将CUS_6221_2赋值给遥控器头码(客户码)低八位a_CUSTOMER_2，随后即开始发送NEC遥控码。 NEC引导码发送并开始编译:
