请帮提供蓝牙(从属设备)中断处理程序

大家好:

    我们购买了BT-MSPAUDSOURCE Tools Bluetooth and MSP430 Audio开发板(MSP430F5229),希望提供中断处理程序(最好主设备,从属设备各一套);最好完整一些(宏定义,初始化,执行完整部分)  

      谢谢!

  • 有些不太理解您的意思。能否详细描述一下

    您现在是说的哪部分的中断处理程序?

    之前已经在相关帖子内回复了

    SuSan,  您好:

         按照“蓝牙传输”的理论, 我们希望蓝牙主设备采用“广播方式”发出数据包;蓝牙从设备接收到数据,产生中断,解析数据包内容,进行相应处理!

         我们使用的MSP430F5229芯片(开发板是:BT-MSPAUDSOURCE Tools Bluetooth and MSP430 Audio开发板),我们希望以它为基础的

    蓝牙(从属设备)中断处理程序

    大家好:

       您看如下的MSP430的蓝牙接收中断处理程序,改装时注意几项?

       

    #pragma vector = USCIAB0RX_VECTOR //接收中断
    __interrupt void USCI0RX_ISR(void)//中断程序,串口通讯的规则设计
    {
        while ( !(IFG2&UCA0TXIFG) ); //确保发送缓冲区准备好
        a=UCA0RXBUF;

        if (a=='1')
       {
            b++;
            flag=1;
        
            P1OUT^=BIT0;

         }
       
        UCA0TXBUF=UCA0RXBUF;
        IFG2 &=~ UCA0TXIFG;
        //接收指示灯状态改变
     }

    大家好:

         经过“理论“确认,USCI_A0_VECTOR(HCI_RX_1V8_CC---->MSP430F5229的37管脚:P3.3/UCA0TXD)正是我们蓝牙的主接收端口!

         但我们将这个中断处理程序写入后, (

              请参考:

             

    // Echo back RXed character, confirm TX buffer is ready first
    #if defined(__TI_COMPILER_VERSION__) || defined(__IAR_SYSTEMS_ICC__)
    #pragma vector=USCI_A0_VECTOR
    __interrupt void USCI_A0_ISR(void)
    #elif defined(__GNUC__)
    void __attribute__ ((interrupt(USCI_A0_VECTOR))) USCI_A0_ISR (void)
    #else
    #error Compiler not supported!
    #endif
    {
      switch(__even_in_range(UCA0IV,4))
      {
      case 0:break;                             // Vector 0 - no interrupt
      case 2:                                   // Vector 2 - RXIFG
        while (!(UCA0IFG&UCTXIFG));             // USCI_A1 TX buffer ready?
        UCA0TXBUF = UCA0RXBUF;                  // TX -> RXed character
        break;
      case 4:break;                             // Vector 4 - TXIFG
      default: break;
      
    }

     

    程序下载后就跑飞了, 不能跳转到main()入口处!

    如何破解?

    单从这段代码看,是没有问题的。方便的话建议提供完整代码或工程。

    谢谢! 请帮参考!

    奇怪的是: 如果没有加上那段(#pragma vector=USCI_A0_VECTOR......)中断处理程序,一切正常!

    但......A3DPDemo_SNK.zip

  • 回复 user5274273:

    大家好:
    在这个应用中,我们希望解决如下问题:
    1). 用“GAP_LE_Perform_Scan(”获得当前范围内的“蓝牙设备”,用中断处理程序"USCI_A0_ISR"来获得它们的“设备名称”
    2). 指定自己为“主设备”, 其它特定的设备为“从设备”
    3). “主设备”广播发送数据,同步“从设备”

    请问我们的实现策略合理吗?
  • 回复 user5274273:

    1 您可以使用GetRemoteName 来获取设备的名称

    /* The following function is responsible for querying the Bluetooth */
    /* Device Name of the specified remote Bluetooth Device. This */
    /* function returns zero on successful execution and a negative value*/
    /* on all errors.

    2 您可以使用HCI_Role_Discovery来查看当前的role

    static Boolean_t LocalDeviceIsMaster; /* Boolean that tells if the local */
    /* device is the master of the */
    /* current connection. */

    3 您是想通过广播来同步?

    另外建议您若是遇到新问题请重新发帖,以便于回复与查看,谢谢
