How to use pdm to pcm conversion library?
I am working on a project where I need to calculate the ambient noise in a given environment in decibels, for that purpose I am using st microelectronics's MP34DT01-M microphone which has an digital PDM output. From the stm application notes I got t...
IIS2DH sensing Die Location
Where in the 2x2 package is the sensing die for the 3 axis located? Is it dead center? A technical answer as accurate as possible would be best. And if there is some known manufacturing variance of this location. Thanks
Interrupt generation for activity event
Hello,I have configured LIS2DH12 to generate interrupt on INT2 pin on activity as well as a strong impact using the register values as follows:CTRL_REG1 - 0x37CTRL_REG2 - 0x00CTRL_REG3 - 0x40CTRL_REG4 - 0x88CTRL_REG5 - 0x0ACTRL_REG6 - 0x28INT1_THS - ...
LSM9DS1 magnetic sensitivity
Posted on July 10, 2018 at 16:40The magnetic sensitivity for the LSM9DS1 is 0.14 mguass/LSB on its most sensitive range. The LIS2MDL is 1.5 mguass/LSB. Is the LSM9DS1 really 10X more sensitive? If so, it would seem the best choice for application...
FSM#11: How to… test your FSM: SHAKE detection, further algorithm examples
This example describes how to set up a finite state machine to enable the built-in detection of a SHAKE action along x-axis. The picture here below shows the steps of the dedicated FSM. SHAKE FSM allows you to check when a double shake event is detec...
A3G4250 gyroscoppe questions ?
Dear ST Members,How can convert the register output X,Y,Z to dps ? I read on datasheet , the range is +/- 245 dps. What's "dps" ?Best regards,Bianchi

VL53L1X can't connect with MCBSTM32 Evaluation Board
Hello I have a MCBSTM32F103 Evaluation Board but I can't connect it with the VL53L1X Satel. I use Keil, first I have include the API to use the functions. Then I use the VL53L1X expansion board Code and modify the platform.c and the main. If I compil...
LSM6DS3 Timestamp read in FIFO issue
I have a LSM6DS3 sensor connected to a MCU by SPI. My goal is to fill the FIFO buffer with the following sets of data: Gx, Gy, Gz, XLx, XLy, XLz, Ts, Pd. I am using a watermark to generate an interrupt once a specific FIFO level is reached. Furthermo...
