PIC 到 PIC UART 通信使 LED 闪烁

Question

我想通过UART将PIC12F1572的命令发送到另一个PIC12F1572 并且我想发送一个函数，使从 PIC 上的 LED 闪烁。我已经完成了一些代码，但我有些困惑有人能帮我一下吗？ P.S- 我正在使用 MPLAB X IDE v3.50

Master/Transmitter PIC12F1572:

    #include <xc.h>
    #include "main.h"
    #include "config.h"
    #include "TYPEDEF_Definitions.h"
    #include "PIC_12_Timer0.h"
    #include "PIC_12_UART.h"
    #include "System_init.h"
    #include "Pin_manager.h"
    #include "LED.h"

    #define _XTAL_FREQ 16000000
void main()
{   
    SYSTEM_Initialize();
    //pin_config();
    LATA = 0x00;  
    UART_Init();                  //Initialize UART
  // StartLedBlinkingWithColor(color);

    TRISAbits.TRISA2  = 1; //make RA2 as input

    while (1)
    {   
      //LATAbits.LATA2 = 1;
      uint8_t Var = 0x61;
       //uint8_t Var = LATAbits.LATA2;

        if(TXSTAbits.TRMT == 1)
            {

                  UART_write(LED_Blink()); // is it possible?? or how it will be possible

                 // __delay_ms(1000);
            }

       LATAbits.LATA2 = 1;


    }
}

void LED_Blink()
{
       LATAbits.LATA2   = 1; 
       LATAbits.LATA5   = 1; 

       __delay_ms(1000);


       LATAbits.LATA2   = 0; 
       LATAbits.LATA5   = 0;


}

RECEIVER/SLAVE PIC12F1572:

#include <xc.h>
#include "config.h"
#include "PIC_12F_GPIO.h"
#include "Led.h"
#include "Interruptmanage.h"
#include "PIC_12F_UART.h"
#include "PIC_12F_TIMER0.h"
#include "main.h"

void main( void)
{
    uint8 data;   

    InterruptInit();
    TIMER0_Init();
    UART_Init();
    InitLeds(); // here I init GPIO pin..no prb here

    // SetLedOff();

    /*-------------R E C E I V E R*------------*/
    while (1) 
    {   // Endless loop

        if (UART_DataReady() )     // I get prob here ..
        { 
          PORTA = UART_ReadOneByte(); // read the received data, [how can I receive my Led_Blink() function??
          LATAbits.LATA2   = 1;      
          //LATAbits.LATA2 = data;

          //SendByteSerially(data);
        }
     }
}

Answer 1

有几件事需要考虑：

您无法通过 UART "send a function"。因此，LED_Blink()函数需要在接收端。在执行任何其他操作之前，请验证该函数在接收器端是否有效，无需任何 UART 交互。
接下来，您可以定义一个 protocol，它基本上决定您通过 UART 发送的字节值应该触发接收方的 LED_Blink() 调用。例如，如果您决定使用字节值 42 来触发 LED 闪烁，您的发送方将调用 UART_write(42)，而在接收方，您将调用如下内容：
```
data = UART_ReadOneByte();
if (data == 42) {
    LED_Blink();
}
```

所以为了从 UART 接收数据并将其保存在数组中并使用数据 vlink nthe LED 我已经完成了这段代码：任何有兴趣的人都可以看看

 while (1)
 {

        if (EUSART_DataReady)
        {
            for (i = 0; i<FRAMESIZE; i++)   //#define FRAMESIZE 19
            {
                RX_Buffer[i] = EUSART_Read();
                if (RX_Buffer[i] == '\n')        //check'\n' in the end of frame
                   break;
            }

            RX_Buffer[i] = '\n';                        //append '\n' at the end of stoaring array for detection of frame
            RX_Buffer[i+1] = '[=10=]';                      // End of an array
            EUSART_WriteAnArrayOfBytes(RX_Buffer);


        if(RX_Buffer[0]=='R' && RX_Buffer[FRAMESIZE-2] == '\n')   //check for correct frame
          {

            LATAbits.LATA2 = 1;
            __delay_ms(2000);
            LATAbits.LATA2 = 0;
            __delay_ms(1000);
          }
        }

  }
