Configuration wrong and calibration wrong for ISM330DLC

Hello I'm acquiring data from an ISM330DLC per I2C, and I'm having several issues:-I probably have the config wrong several levels. For instance I have the Reg CTRL1_XL configured to 0x75, CTRL2_XL to 0x7C, CTRL8_XL to C8, CTRL7_G to 40, CTRL6_C to 0...

IIS3DWB temperature sensor offset

HelloIn the IIS3DWB datasheet, it is said that the embeddeed temperature sensor offset can vary within a [-15°C : +15°C] range.Does that mean that the reading from OUT_TEMP_H/L can vary within [-256*15 LSB : +256*15 LSB] at 25°C ?Having tested 2 chip...

Resolved! LSM6DSR is never setting XLDA in status reg.

I am trying to validate a new board layout and am looking for the minimal configuration to read accel data.I'm using SPI.  When the WHO_AM_I register of the LSM6DSR is queried, the correct response of 0x6B is returned.I take that as validation of the...

Resolved! IIS3DWB bandwidth

Hi,The LPF2 filter on the IIS3DWB can set the cutoff frequency to ODR/4, ODR/10, ODR/20, etc. Figure 6 in the datasheet "Frequency response with LPF2 enabled" shows the bandwidth when LPF2 is set to ODR/4 to be 5.6 kHz. Is this correct? ODR/4 would...

LIS3DH noise while access with I2C

Hi,It seems that accessing the i2c bus add noise to acceleration values read by the LIS3DH. The graphic represent 270 X,Y,Z 10bit samples read at 1344KHz. The FIFO is enable and a watermark level interrupt of 28 is set. At each interrupt, I'm doing a...
