LIS3DH output register value less than the set threshold
I use the lis3dh sensor to communicate through SPI, and the sensor settings are as follows：lis3dh_gvWriteReg(LIS3DH_CTRL_REG0,0x90);lis3dh_gvWriteReg(LIS3DH_CTRL_REG1,0x37);lis3dh_gvWriteReg(LIS3DH_CTRL_REG2,0x00);lis3dh_gvWriteReg(LIS3DH_CTRL_REG3,0...
Resolved! LIS2DH12 Self Test
We are running the LIS2DH12 self test. After completing the self test we go back and read stat reg 27 it is always returning FF. We have tried reading it multiple times, but it always returns FF even if no new data is available.
Resolved! LIS3DHH ODR variation
Digital output data rate (ODR) of LIS3DHH is given (typically) as 1.1kHz in the datasheet. Does it mean ODR is not fixed in one sensor or it is fixed in one particular sensor but there is an inter device variation ? In either case, I am confused how...
LIS3DH conflicting specification in datasheet
Hi,the LIS3DH datasheet (DocID17530 Rev 2) states on page 1 under Features:"Embedded 32 levels of 16-bit data output FIFO".However, on page 19, section 3.6 FIFO:"The LIS3DH contains a 10-bit, 32-level FIFO"Which statement is correct?
Resolved! STEVAL-MKI109V3 does not interpret Z axe value
Hello, I'm using the STEVAL-MKI109V3 board in combination with STEVAL-MKI175V1 and trying to read the X, Y and Z values through the serial port using the commands described in the STEVAL-MKI109V3 documentation and I'm unable to see the Z axe value af...
LIS2DW12TR INT1
Hi Sir/Mam,I am using LIS2DW12 accelerometer for wake-up detection. I can detect the wake-up event by reading theregister,and I set the wake-up recognition routed to INT1 pad, but I do not see that an INT1 interrupt being raised.This is my configure...
How many times can "RPDS" register be written in the ILPS28QSW?
I'm trying to use ILPS28QSW as a water level sensor. For that I want to convert the pressure into mmH2O. In order to make that conversion as easy as possible I'd like to substract the atmosferic pressure. The datasheet shows that there are two regist...
H3LIS331DL
Hi, I'm Working with H3LIS331DL Accelerometer and STM32F410 for vibration test(Levels:0.04 g^2/Hz,2O Hz to 2000 Hz All 3 Axis, 5 Minutes each axis) at SPI mode.I have readed the raw data from the H3LIS331DL and communicated it by UART. But after tha...
Init sths34pf80.c / sths34pf80.h
I am looking to interface with a sths34pf80 on a nucleo-f401re. I want to set up I2C to R/W to the registers and use the included functions. BSP_I2C1_Init(); uint8_t ret=0; STHS34PF80_Object_t pObj; STHS34PF80_IO_t pIO; STHS34PF80_Init(&pObj); STHS3...
