MEMS (sensors)

Hi, i need some help writing code of Heart Beat sensor max0100 I connected it to STM32L476 Discovery controller and activated the I2C pins in the STCUBE32IDE program. I dont know how to configure the MAX30100 in order to work with the controller

LIS2DH taking more than 100 uA

We are using LIS2DH in our board for production. Among 1000 boards, about 50 boards were drawing much more power because of LIS2DH (the IC is functional - we are getting the accelerometer data). Once we remove the IC from the board, current dropped f...

Need soldering temperature profile for LIS2DE12

Hi, I am mounting the LIS2DE12 IC's using Infrared IC reflow machine using the profile having 257 °C peak. IC got soldered but, it is not detected, when I tried to communicate with it. I have tried for 3 IC's with same resulted. I suspect the t...

Is there a maximum speed of an object that a VL53L1X sensor can detect?

I am working with the sensor to detect objects passing in front of it, but wonder if there is a max speed that the sensor can accurately detect. Thanks!

(LIS3DH) What will be the slave address if the SDO/SA0 neither wired to VSS nor GND?

I have a board that uses LIS3DH. Unfortunately I find the SDO/SA0 pin does NOT wire to VSS or GND. In this case, what would be the Slave ADdress(SAD)? In the spec it says 001100xb and the 'x' is either 1 or 0 when connected to VSS or GND. But no clu...

Hi sir/madam, We are using L3GD20HTR part in our design. We need recommended PCB land pattern for IC L3GD20HTR to create Footprint. Kindly share at the earliest.

Dear Sir, How to connect Sensor tile cradle expansion board to PC and I tried with ST youtube video. But I unable to connect. My second question is I want to save the sensor tile Acceleration and Gyroscope data to the sd card. I requerst you suggest me

I want a 1000 data per seconds from LSM6DSM sensor (Acceleration and Gyroscope data ) and I want set acceleration level should +16g to -16g and gyroscope value should be 2000dps. These data should saved to the sd card. I request you to kindly sugges...

Problems calibrating VL53L0X ToF distance sensor (VL53L0X_perform_offset_calibration, VL53L0X_perform_xtalk_calibration). bug?

RoutineVL53L0X_perform_offset_calibration from src/core/src/vl53l0x_api_calibration.cpp is giving strange results. By my opinion the problem is in uint16_t sum_ranging which should be of type uint32_t due to later bit shifting (<<16), which needs to ...

multiple VL53L0x interfacig with atmega 2560

I want to interface 3 VL53L0x with atmega 2560 using arv-gcc and not arduino but i am unable to do so I have its documet but i dont understand how to implement please .Please help me to interfcae all sensor and read all of them at same time
