Hello,
I'm facing issues when enabling LIS3DH click interrupt, AOI1 and AOI2 interrupts on INT2 pin. These interrupts works fine on INT1 pin.
Following is the flow I do to enable click interrupt on INT2 pin.
register - 20h value - 119 //ODR 400Hz and all axis enabled
register - 21h value - 0 //HPF disabled
register - 22h value - 0 //No interrupt enabled on INT1 pin
register - 23h value - 8 //High resolution output mode
register - 24h value - 0 //Interrupts not latched
register - 25h value - 128 //Click interrupt on INT2 pin
register - 38h value - 5 //Detect single click on x-axis and y-axis
register - 3Ah value - 10 //Threshold 1.5m/s^2
register - 3Bh value - 120 //Time limit 0.3s
register - 3Ch value - 120 //Time latency 0.3s
register - 3Dh value - 120 //Time window 0.3s.
I enable the click detection, read the click status register and transmit over serial. I'm observing the INT2 interrupt pin using a DSO. The click is getting detected by the sensor which is evident from the status register value but the INT2 pin is always low. If I change 25h to 0 and 22h to 128 I get an interrupt on INT1 pin without any problems.
I checked for dry solder on INT2 pin but there is no problem.
