Accelerometer report invalid raw data after configure some registers.
I'm using LSM6DSV, and use it wake-up funciton, I will configure registers when wakeup, that time I got some invalid data such as "1.998665088 1.998665088 1.998665088", how to avoid it?
FSM#2: How to… structure your FSM: a general overview
From theory, we define a Finite State Machine (FSM) as an abstract machine that can be in exactly one of a finite number of states at any given time, and is composed of a START state, a STOP state and a series of states, conditions and transitions. B...
LPS22DF Temperature compensation
Hi,I want to compensate for the temperature of the LPS22DF sensor.how does one go about programming for it? Is this formula correct?Pcorrected=Pmeasured−(TCF×(Tmeasured−Treference))If it is, should I use a temperature reference value of 25°C?Also...
Resolved! magnetometer Calibration Library does not work
Hello, I am working on a custom board based on STM32F407 CPU with the LSM6DSV16XTR accelerometer+gyroscope and LIS2MDLTR magnetometer.The aim is to get board inclination and compass information with the maximum accuracy.The MotionFX library seems ...
Resolved! LPS22DF I3C addressing
Dear forum,We plan to assemble five LPS22DF sensors on the same I3C bus and (off course) to address them individually. According to the datasheet (7.4.1 MIPI I3CSM CCC supported commands) the answer to GETPID can only have two values, depending on SD...
How can I manually control the background calibration of my IIS2ICLX-Accelerometer?
hi!I have a problem with the calibration of the IIS2ICLX-Accelerometer. I see there is happening a calibration but because I make a sensor fusion in the next step, I want to have the calibration fixed once its done. In the data-sheet and the forum I ...
Resolved! Extend operating range of LPS28DFW using autozero functionality
I am working on a project using the LPS28DFW pressure sensor to monitor depth in water (~1000mBar / 10m), the sensor has a max operating range of up to 4096 mBar limited by its 24 bit 2s compliment output. As far as I can tell the negative half of th...
LSM6DSV IMU sensor hub with external 3-axis 18-bit high precision magnetometer sensor
Hello,We want to use LSM6DSV IMU sensor with external 3-axis 18-bit high-precision magnetometer sensor through IMU sensor hub function also with its FIFO function. We refer to following LSM6DSV sensor hub example:https://github.com/STMicroelectronics...
LIS3MDL not responding over SPI on custom PCB
Hi,I'm designing a flight controller pcb using several ST mems sensors, (LSM6DSO, LIS3MDL, LPS22HH) and interfacing them to an STM32H743IIT6 microcontroller over a shared SPI bus. I'm on the second iteration of this board, all sensors worked on the f...
