I'm using an H3LIS331DL chip, and relying on the set threshold to trigger an interrupt and go read the data.Everything is working fine, except occasionally it will freeze and stop reading anything. On investigation, I found the interrupt output line ...

I have the FS bits set for +/-100g scale.The accel data is a 12-bit signed value, meaning each bit represents 0.049g.The threshold registers however is only a 7-bit value. From what I understand, this is to be an unsigned magnitude level, representi...

Hi Eleon,Thanks for the advice.LIR1 bit is enabled.I was leaving the INT1_DURATION as the default, 0.Setting the duration to 1 seems to fix the issue. Interrupts are cleared immediately upon reading the INT1_SRC. The interrupt then stays low for 2 sa...

Further info:If I repeatedly send a read request to the INT1_SRC register until it clears, the interrupt finally clears at almost exactly 10ms later. I'm running at 100Hz ODR, so that's 1 data sample period.The interrupt stays low for 2 sample perio...

Thanks for the quick response.Yes, I'm setting the INT1_CFG to enable all 3 axis, high events only.I'm running in low power mode with 10 Hz ODR.Upon interrupt I'm first reading all 6 registers containing the x/y/z values. Then I'm clearing the inter...
