MEMS (sensors)

Why can't I send an app to my SensorTile using ST BLE Sensor and Create Apps on iOS?

For my SensorTile, when I open the ST BLE Sensor app then create/use an app in Create Apps and tap Play, I get a "Board scanning has timed out" error message. Everything under "Connect to a device" interacts happily with the SensorTile. What's the pr...

VL53L1X, time data

Hello, I have bought VL53L1X to use it on a physics project. My project is about measuring the speed of light in air and some other fluids. As far as I understand, this sensor does not measure distance directly, but measures the time delay between th...

STM32L4xx USB_CDC Class Configuration on SensorTile: Why Timer is needed?

Dear,From the SensorTile Sample Code (STSW-STLKT01). The USB CDC device class is set up with some function of Timer3. I do not understand why Timer3 is used and how useful to do so. Will someone please help me to understand this?Please refer to the c...

Receiving wrong value for "Who am I".....Always getting 255 in received data (both bytes)

I am using STM32F429 Discovery board and trying to communicate to on-board MEMS L3GD20 Angular sensor using SPI protocol. Problem is not receiving correct data as per Angular sensor. I am receiving value decimal 255. Where I am making mistake? Please...

Hi i have a problem with a sensor vl53l0x on the board b-l475e-iot01a. In particular when i use the VL53L0X_PROXIMITY_GetDistance() in a task with HAL_Delay() it work but when i use the osDelay it work only for a repetition of the for(;;).

If i use 2 task, and in first task put the VL53L0X_PROXIMITY_GetDistance() with osDelay, second task never start. I tried to replace osDelay() with other function for context switch but i have same problem.

The LIS3MDL magnetic data are 16bit left-justified. I deserialised the the Data to a int-16 value. How can I interprete the "left-justified" remark? Do I have to shift the Answer?

Local Communication by using multiple VL53L1x

Hi, I plan to use a VL53L1x sensor pair to implement a very low-bandwith local communication as a side duty of ranging. For this purpose I need to be able to precisely control laser emission of VCSEL. Is is possible to timing VCSEL laser emission by...
