LIS3DH使用两个中断

嗨，

我试图在INT1上启用自由落体中断并在INT2上唤醒。但是只有INT1的自由落体才有效。以下是注册设置：

CTRL_REG1 = 0x6F // 200Hz ODR，启用XYZ
CTRL_REG2 = 0x00 //取消HP过滤器
CTRL_REG3 = 0x40 // IA1中断IA1
CTRL_REG4 = 0x30 // + - 16g FS
CTRL_REG5 = 0x0A //锁存两个中断
INT1_THS = 0x02 // 372mg自由落体阈值
INT1_DURAtiON = 0x03
INT1_CFG = 0x95 //设置自由落体

CTRL_REG6 = 0x02 // IA2中断IA2
INT2_THS = 0x10 //唤醒阈值3g
INT2_DURATION = 0x00
INT2_CFG = 0x2A //设置唤醒


我怀疑它与CTRL_REG6有关。我假设“中断2”是指在INT2_CFG中选择的中断，在这种情况下是唤醒？


问候，

Hi,

I am trying to enable free-fall interrupt on INT1 and wake-up on INT2. However only free-fall on INT1 works. Here are the register settings:

CTRL_REG1 = 0x6F // 200Hz ODR, enable XYZ
CTRL_REG2 = 0x00 // di***ale HP filter
CTRL_REG3 = 0x40 // IA1 Interrupt on INT1
CTRL_REG4 = 0x30 // +- 16g FS
CTRL_REG5 = 0x0A // latch both interrupts
INT1_THS = 0x02 // 372mg threshold for free-fall
INT1_DURATION = 0x03
INT1_CFG = 0x95 // setup free-fall

CTRL_REG6 = 0x02 // IA2 Interrupt on INT2
INT2_THS= 0x10 // wake-up threshold 3g
INT2_DURATION = 0x00
INT2_CFG = 0x2A // setup wake-up


I suspect it has to do with CTRL_REG6. I'm assuming "interrupt 2" refers to the interrupt selected in INT2_CFG, which in this case is wake-up?
