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 // disbale 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?
