Range setting in ISM330DLC

Hi All,I am working on a project that is using ISM330DLC sensor for measuring the acceleration along the X,Y and Z-axis. When I set range 2G,4G and 8G I'm seeing difference in the sensor raw value and when I set it to 16G, I'm getting same data as 8G...

LSM6DSl edge-sensitive trigger mode

Hello,I want to use edge-sensitive trigger mode to synchronize multiple sensors. In the code snippet you can see the relevant code for that. The FIFO buffer doesn't get filled, even though I have a PWM as trigger on the INT2 pin. The low-pass filter ...

LSM6DSL: Interrupts aren't latched when the LIR Bit is set to 1

Hello,Even though I have set the LIR bit to 1, the interrupts aren't latched. In the picture you can clearly see that the interrupt is reset before reading the route register of interrupt 1. The LIR bit is definitely set to 1. I have checked this wit...

What is the Res pin for in the LIS2DH12 MEMS Accelerometer?

The datasheet pin description table Function column simply states “Connect to GND�?. Every other pin in the table has their function described, but “Connect to GND�? says nothing about its function. Is this a reset pin (active high)? If so, can it be...

LSM6DSL: Why isn't the gyroscope data appearing in the FIFO?

I am trying to use the FIFO to store accelerometer and gyroscope data on the LSM6DSL. While the acceleration data appears correctly in the FIFO, the gyroscope x and y axis data is only being stored as zeros. The gyroscope z axis data is being stored ...
