I have question regarding the accelerometer LIS2DH12.I'm trying to configure the interrupt, to trigger when e.g. the x-axis goes above a threshold value. Not sure what to put in the INT1_THS register?and, in the output registers (OUT_X_L and OUT_X_H)...

Sorry, just saw the multiplication by 4 to convert it to mgSo first get the LSB correct converting from 16bit to 10bit (Normal mode) by right shift by 6.This value is still in LSB, then multiply by 4 (because 4mg/LSB) to get it to mg.Then divide by 1...

Ok, but you wrote2000LSB --> 2000/16 mg = 0.125g So assumed that it was dividing by mg. But maybe not your intention. I'm using Normal Mode (10bits), so I should right shift by 6 then?15000 >> 4 = 234mg = 0.234g ?Doesn't look correct.

Thanks for the response!But why are you dividing by 16mg, when it says 4mg/LSB for +-2g in Normal Mode? Not quite sure I understand.But, the numbers are adding up when dividing by 16mg, cause when the x-axis are pointing down with no movement, I rea...

Got it to work now! Think it might have been the magnetometer (LIS2MDL) connected to the same SPI-bus that was sending out some garbage. Saw that when CS is high the sensors are configured for I2C.When I configured the magnetometer sensor in my devic...

sometimes the raw values are '255'. My setup is Zephyr RTOS with an nrf5340 MCU interfacing the LIS2DH12 with SPI.When I have this issue and reading the CTRL_REG1 and CTRL_REG4 the values are corrupted. CTRL_REG1 = 0x00 and CTRL_REG4 = 0xFFBut when i...

How to understand Accelerometer LIS2DH12 output value, and how to configure the INT1_THS register

Hi, I'm trying to use the accelerometer sensor LIS2DH12, and having some issues reading data from it. Sometimes it works fine, but when re-flashing the device it doesn't work. I try to power-cycle but still issue with it. The values are all '0'
