MEMS (sensors)

How do I get the FP-NET-BLESTAR sample code to start sending all sensor data (acc, gyr and mag) from the STEVAL-STLCS01V1 sensor tiles?

It appears that the functionality is written into the code but I can't figure out how to get it to work. I am using the SW4STM32 IDE to build and compile and I know that in main.h there is #define ENABLE_MEMS 0 which can be changed to a 1 but the .h ...

LSM9DS1 I2C address confusion

I have confusion about I2C address for magnetometer.As in the datasheet at page 11:SDO_M: I2C least significant bit of the device address (SA0) for the magnetometerBut in the table 20 page 30:See picture enclosedIt looks like the SDO_M pin is used fo...

Sparse LIS331 Datasheet(s)

Posted on July 12, 2018 at 08:16Dear all - especially STM developers,I recently integrated an LIS331HH sensor. It seams to be very nice sensor! But anyway while reading LIS331 Datasheet, I found that information required for proper MCU driver implem...

VL53L0x API data access inconsistency

The VL53L0X API (https://my.st.com/content/my_st_com/en/products/embedded-software/proximity-sensors-software/stsw-img005.license=1533144599665.html) requires definition of a platform-dependent structure of type VL53L0X_DevData_t. This structure must...

Using VL53L1X to detect ping pong balls on a table tennis board.

Hi all,I am designing an application which would tell me, if a ping pong ball lands on a particular area of a table or not. Below is a sketch that illustrates:Sensors would be placed on left side of the table, facing the other side as shown in the ab...

VL53L1X: Is there only one kind of calibration (API), or there is a calibration that is made by ST for their dev. and breakout boards?

When I use the breakout board included in the dev kit, the precision is at most 2 mm, but when I use the VL53L1X soldered on one of my board, the precision is really different. Is there a particular calibration or setting that are input to the breako...

ISM330DLC : Noise Issue

Posted on July 16, 2018 at 08:55Hi,I am using ISM330DLC  accelerometer and gyroscope sensor.I have initialized the accelerometer & Gyroscope register and reading the respective X,Y,Z register and that is providing huge noise in gyroscope values. And...

Is there a way to detect overflow with LIS2MDL?

Posted on June 06, 2018 at 19:15GreetingsI am using the LIS2MDL to build a magnetic field sensor for the education market.  When the magnetic field being measured exceeds the maximum allowed value, I notice that the LIS2MDL returns unpredictable dat...

I am using the lsm6dsl chip. It is used SPI communication mode 3 in datasheet. However, It's communicate in mode 0 in actual test. Is there anything wrong with using mode 0 in continuous?

LSM6DS3 activity/inactivity recognition: restore activity by software
