LIS3DH如何正确配置INT2以使其工作？

你好！
我试图检测冲突并在INT1上产生中断，并检测运动并在INT2上产生中断。 INT1正常工作，但INT2不起作用。好像我错过了一些东西......
这些是我在寄存器中的值：

CTRL_REG0 = 0x90 //上拉与SDO / SA0断开pinCTRL_REG1 = 0x27 // HR /正常/低功耗模式（10 Hz），Z轴启用，Y轴启用，X轴启用
CTRL_REG2
= 0x01 //在中断时启用AOI功能的高通滤波器2CTRL_REG3 = 0x40 //启用INT1时IA1中断
CTRL_REG4 = 0x88 //输出寄存器直到MSB和LSB读取才会更新，启用高分辨率
CTRL_REG5 = 0x00 //正常模式，FIFO禁用，中断请求未锁存
CTRL_REG6 = 0x28 // INT2引脚使能中断2功能，使能活动中断


INT1_CFG = 0x95 //

和逻辑。启用XLIE，YLIE和ZLIE中断生成.INT1_THS

= 0x32 //阈值（THS）= 50LSBs 15.625mg / LSB = 781.25mgINT1_DURAtiON

= 0x00 //持续时间= 0LSBs（1 / 1Hz）= 0s.//0x78 - ＆gt; 120s INT2_CFG = 0x95

//


和逻辑。启用XLIE，YLIE和ZLIE中断生成。
INT2_THS

= 0x08 //阈值（THS）= 8LSBs 15.625mg / LSB = 125mgINT2_DURATION

= 0x0A //持续时间= 10LSBs（1 / 1Hz）= 10s
有没有人知道如何正确配置INT2以使其工作？


谢谢！

Hello!
I am trying to detect a collision and generate an interrupt on INT1, and also to detect motion and generate an interrupt on INT2. INT1 is working normally, but INT2 does not work. It seems I am missing something...
These are the values I put at registers:

• CTRL_REG0 = 0x90  // Pull-up disconnected to SDO/SA0 pin
• CTRL_REG1 = 0x27 // HR / Normal / Low-power mode (10 Hz), Z-axis enabled, Y-axis enabled, X-axis enabled
• 
  CTRL_REG2
  = 0x01 // High-pass filter enabled for AOI function on interrupt 2
• CTRL_REG3 = 0x40  // IA1 interrupt on INT1 enabled
• CTRL_REG4 = 0x88 // Output registers not updated until MSB and LSB reading, high-resolution enabled
• CTRL_REG5 = 0x00 // Normal mode, FIFO disabled, interrupt request not latched
• CTRL_REG6 = 0x28 // Interrupt 2 function on INT2 pin enabled, activity interrupt enabled
• INT1_CFG = 0x95 //
  
  
  AND logic. Enable XLIE, YLIE and ZLIE interrupt generation.
• INT1_THS
  
  = 0x32 // Threshold (THS) = 50LSBs  15.625mg/LSB = 781.25mg
• INT1_DURATION
  
  = 0x00 // Duration = 0LSBs  (1/1Hz) = 0s.//0x78 --> 120s
  

• INT2_CFG = 0x95
  
  //
  
  
  
  AND logic. Enable XLIE, YLIE and ZLIE interrupt generation.
• INT2_THS
  
  = 0x08 // Threshold (THS) = 8LSBs  15.625mg/LSB = 125mg
• INT2_DURATION
  
  = 0x0A // Duration = 10LSBs  (1/1Hz) = 10s
  

Does anybody know how to configure INT2 correctly to make it work?


Thanks!
