MEMS (sensors)

Why ranging Time-of-Flight sensor (VL53L1X) gives fluctuate value for fixed distance?

While measuring the distance of an obstacle using VL53L1X ( https://www.st.com/en/imaging-and-photonics-solutions/vl53l1x.html ) the result is fluctuating. This was tested with the breakout board ( https://www.st.com/en/evaluation-tools/vl53l1x-satel...

How to set ATime, MTime and FrTime parameters to calculate position with low error

Hi,I modified the example program "Data Log Fusion" to calculate the position by integrating twice the linear acceleration. However, there is an error on linear acceleration that is very consistent both when the board is moving and the board is stati...

Sample Drivers working with an ESP32 Has anybody been able to get the sample drivers to work with an ESP32. The only examples I can find are from people who have written a new driver. I am trying to use an IIS3DWB over SPI

How do I flash original Sensortile mobile app code?

When I received the Sensortile chip, it had the mobile app code flashed on it.I was working on developing on the Sensortile chip, so I flashed my own .bin file onto the chip using ST-LINK Utility.Now I want to revert back to the mobile application co...

Not able to communicate with Unicleo-GUI using USB virtual COM port on STM322F446RE.

We are able to retrieve microphone sensor data and view on Unicleo-GUI using serial port on STM32F446RE.While trying to port the microphone sensor data to USB virtual COM port the Unicleo-GUI is not responding.It is observed the data is not received...

Is there another driver to get BOTH data buffer instead of VL53L1_GetRangingMeasurementData()? This one ONLY returns one result then I can't calculate a "shift" by using just one sensor.

VL53L1_GetRangingMeasurementData() ONLY returns data[0] buffer as result. It means that I will get just the result of ONLY one of the two sensor in the matrix. I'm trying to implement your "people counter" posted on youtube (https://www.youtube.com/w...

How to completely power down the lsm9ds1?

I'm using the lsm9ds1 as part of a bought module - the arduino nano 33 ble - which can achieve very low power (micro amps) in a power down mode. However, If I initialize and read accel and gyro data from the IMU, afterwards I can't find a way to get ...

Battery level using bluepy and FP-SNS-ALLMEMS2

HelloI had download the firmware FP-SNS-ALLMEMS2 on my STEVAL-MKSBOX1V1. From de app I can read the batery level, and I want to do the same with my raspberry and using bluepy. I have a script where I read the temperature and humidity values, so I wan...
