标签：IAR0 HT66F3185 JMP address MOV 发送 MP0 串口 data

要求：

1、主機通過向從機發送0XAA, 0X12, 0X34, 從機接收正確回傳0X55，接收錯誤回傳0XEE

2、通過按鍵切換顯示計數：

主機顯示正确計數n1。另外收發超時機制也要列入錯誤計數處理，通信間隔為10ms 一次。
主機顯示錯誤計數n2。

从机接收数据的想法：存储数据后进行判断，再由串口发送0x55,0xee给主机

和C语言不同，不能用数组，只能采用MP0,IAP0的方法来存储数据(具体方法可以看手册）

下面两行是数据的存储，将ACC存储的值，放入IAR0中，再移动MP0 的地址，使IAR0指向下一个存储区

        MOV        IAR0,A　　　　　　　　　　　　　　　
        INC        MP0                            ;Put data into address

举个例子，将TXR_RXR的数据存储在MP0所指的地址存储区，利用IAR0进行存储（1~10），

数据的大小根据自己的需求决定（11~15），

最后再将地址，和存储大小初始化就好了

 1 ;It is convenient to view the received data in RX_BUF        
 2         MOV        A,TXR_RXR            
 3         MOV        RX_BUF,A                    ;RCE BUF
 4         
 5 ;TXR_RXR=IAR0，Put data into address        
 6         MOV        IAR0,A
 7         INC        MP0                            ;Put data into address
 8         INC        COUNT
 9 
10 ;storing 3 data
11 ;//--  if want to store more data ,plase change 3     --//    
12         MOV        A,3
13         SUB        A,COUNT
14         MOV        VALUE,A                        ;SEND 5 DATAS
15         SZ        VALUE
16 ;//--  If you add the following code,plase change 5  --//         
17         JMP        $+5                        
18         
19 ;addr and count init        
20         MOV        A,ADDR                        ;Read data from this address
21         MOV        MP0,A
22         MOV        A,0
23         MOV        COUNT,A                        ;COUNT INIT

数据的取出判断，也是同理。地址随着循环指向下一个，再将IAR0的数据提取出到ACC

        INC        MP0
        MOV        A,IAR0

以下是取出判断的完整例子

;//data init and addr init            
        MOV        A,10101010B                    ;reset aa,12,34
        MOV        VALUE1,A
        MOV        A,00010010B
        MOV        VALUE2,A
        MOV        A,00110100B
        MOV        VALUE3,A                
        MOV        A,ADDR                        ;Read data from this address
        MOV        MP0,A

;//judge data        
        MOV        A,IAR0                        ;read data for judging
        MOV        ONE,A
        SUBM    A,VALUE1
        SZ        VALUE1
        JMP        ERROR                        ;if error then out
;        
        INC        MP0
        MOV        A,IAR0
        MOV        TWO,A
        SUBM    A,VALUE2
        SZ        VALUE2
        JMP        ERROR
;        
        INC        MP0
        MOV        A,IAR0
        MOV        THREE,A
        SUBM    A,VALUE3
        SZ        VALUE3
        JMP        ERROR
        
;//ture SET FLAG BIT addr init        
        SET        TURE                        ;flag set
        MOV        A,ADDR                        ;Read data from this address
        MOV        MP0,A
