ADXL345的外部中断出现问题

您需要通过读取寄存器0x30清除ADXL345中的中断。
您已经编写了一个Read Byter（）和Read Ebthe（）函数，展开为一个Read Word（）。在这些例程中保留错误处理。调用I2CyError（）函数并在其中设置断点。然后你的整个程序看起来会更干净。
使用项目-gt；更新组件。一次，项目中有旧的组件版本。
你的PSoC板在3.3V下运行吗？

  You need to clear the interrupt in the ADXL345 by reading register 0x30.
    You already wrote a readbyte() and writebyte() function, expand to a readword(). Leave the error handling within those routines. Call an I2C_Error() function and set a breakpoint there. Then your complete program will look a lot cleaner.
    Use Project -> Update Components..  once, there are old component versions in your project.
    Are you running your PSoC board at 3.3V?

我现在使用了这个代码，我从加速度计读完后马上调用它。
monitorint_source虚空（void）{ /*在这里意味着data_ready 0x80，而0x10意味着活动中断* / uint8 accregvalue；accelerometer_regread（int_source，&；accregvalue）；如果（（（accregvalue &；0x80）= = 0x80）&；&；（（accregvalue &；0x10）！= 0x10））red_write（0）；else if（（accregvalue &；0x10）= = 0x10）green_write（0）；其他red_write {（1）；green_write（1）；} uart_uartputchar（accregvalue）；}
然而我得到相同的结果，data_ready闪烁红色迅速，每隔一段时间，但格林（活动中断）永远闪烁。
你能在readword()功能精心布置的，我不了解我应该做什么有。我的I2C通信工作完美，所以我不知道我为什么要把一个i2c_error()功能在里面，也i2c_error应该做什么我还不清楚。
我已经更新了我的成分，和改变的代码点（PFA）。而根据int_source领导的价值，我使它与中断子程序的变化。
我已经连接的PSoC板无电压等级信息的电脑。我已经连接了3.3V引脚到ADXL345的VCC。
当做，

     以下为原文
  I've used this code now, and I'm calling it right after I read from the accelerometer
    void MonitorINT_SOURCE(void) {
/* Here 0x80 means DATA_READY, while 0x10 means ACTIVITY INTERRUPT */
    uint8 accRegValue;
    Accelerometer_RegRead(INT_SOURCE, &accRegValue);
    if (((accRegValue&0x80) == 0x80) && ((accRegValue&0x10) != 0x10)) RED_Write(0);
    else if ((accRegValue&0x10) == 0x10) GREEN_Write(0);
    else {
        RED_Write(1);
        GREEN_Write(1);
    }
    UART_UartPutChar(accRegValue);
}
    However I'm getting the same result, DATA_READY flashes red rapidly and at regular intervals, but Green(activity interrupt) never flashes.
     
    Could you ellaborate on readword() function, I'm not understanding what I'm supposed to do there. Also my I2C communication is working perfectly so I don't know why I should put an I2C_Error() function in there, and also what the I2C_Error shoudl do isn't clear to me.
    I've Updated my components now, and changed the code a bit (PFA). Instead of LED depending on INT_SOURCE's value, I'm making it change with the Interrupt subroutine.
    I've connected the PSoC board to the PC with no information on voltage level. I have connected the 3.3V pin to the ADXL345's Vcc.

一些柏树套件（我不知道你有哪一个）可以从5V操作切换到3.3V。你需要在3.3V下运行。
用逻辑分析仪检查PSoC的中断输入
作为一个例子，我执行的错误检查功能为您从“CopStand”变量的所有查询中解压。在实践中，你可以把一个“闪烁的红色标志”或类似的东西来表明它不工作或问题的cysoftwarereset() API。

     以下为原文
  Some of the Cypress kits (I am not aware which one you have got) can be switched from 5V operation to 3.3V. You need to run at 3.3V
    Check with a logic analyzer the interrupt input to the PSoC
    The error checking function as I implemented as an example unburdens you from all the queries of the "commStatus" variable. In practice you can put a "Blink red sign" or something similar to show that it is not working or even issue a CySoftwareReset() API.
