请问ADXL345中断没反应该如何配置中断

我也准备用这个芯片。。。。

可以考虑下面经验证过的代码：
buf[0] = XL345_RATE_100;    //Output Data Rate: 100Hz
xl345Write(1, XL345_BW_RATE, buf);
buf[0] = XL345_FULL_RESOLUTION;  //Data Format: +/-16g range, right justified,  256->1g
xl345Write(1, XL345_DATA_FORMAT, buf);
buf[0] = XL345_TAP_X_ENABLE | XL345_TAP_Y_ENABLE | XL345_TAP_Z_ENABLE;  //Enable Z Axis Tap Detection
xl345Write(1, XL345_TAP_AXES, buf);
buf[0] = 0x50;      //Tap Threshold:5G, 62.5mg/LSB
xl345Write(1, XL345_THRESH_TAP, buf);
buf[0] = 0x50;  //Dur:50ms, 625us/LSB, representing the maximum time
      //that an event must be above the THRESH_TAP threshold to qualify as a tap event
xl345Write(1, XL345_DUR, buf);
buf[0] = 0x20;  //Latent: 40ms, 1.25ms/LSB, interval between the first tap and the second tap
xl345Write(1, XL345_LATENT, buf);
buf[0] = 0xF0;  //Window: 300ms, 1.25ms/LSB, time window for a possible second tap event
xl345Write(1, XL345_WINDOW, buf);
buf[0] = XL345_SINGLETAP | XL345_DOUBLETAP; //INT_Enable: SINGLE TAP & DOUBLE TAP
xl345Write(1, XL345_INT_ENABLE, buf);
buf[0] = XL345_SINGLETAP | XL345_DOUBLETAP; //INT_Map: SINGLE TAP& DOUBLE TAP interrupt to INT2 pin, DOUBLE TAP interrupt to INT1 pin
xl345Write(1, XL345_INT_MAP, buf);
 
buf[0] = XL345_MEASURE;   //Power CTL: Measure mode
xl345Write(1, XL345_POWER_CTL, buf);

附件是ADXL345的.h文件。
