LSM6DSO No response on MISO line.

I am trying to read the "Who am I" register of a LSM6DSO. I get no response on the MISO line. I suspect I am not configuring the IMU correctly. I am using a Nucleo-L031K6 connected to a MKI196V1. I attached the code. Am I missing something in the con...

Assistance with using the VL53L4CD ToF sensor, with a NUCLEO-L031K6.

I understand that within the datasheet for the VL53L4CD, there is the ULD that is meant to be used instead of referencing the sensors registers directly with the STM32CubeIDE software.I have download the ULD software for the VL53L4CD (STSW-IMG026) an...

Resolved! Validation of X-CUBE MEMS1 Fusion data

Hi,we are using LSM9DS1 IMU board with NUCLEO L053R8 eval board for our project, we are using X-CUBE MEMS1 Fusion, we've validated the Raw data, and we are getting the Fusion output, we need to validate it. Is there any procedure to find whether Fusi...

Resolved! I2C Error while reading HTS221 temperature and humidity sensor on I-NUCLEO-LRWAN1 extension board.

Hi all, I have been trying to read any data from HTS221 on extension board, and HAL I2C functions returns error.I try to read WHO_AM_I register but HAL_I2C_Memread function always returns timeout so error. Any suggestion would be appreciated, thanks....

I have NUCLEO-L053R8. Now I need to interface LSM9DS1 directly with NUCLEO-L053R8 for testing using MotionFX Library. Is it possible to interface LSM9DS1 to test using MotionFX library? If Yes, Please suggest proper procedure/steps. Thank you.

RCC_APB2PeriphClockCmd, GPIO_InitStructure.GPIO_Pin, GPIO_InitStructure.GPIO_Mode etc. what is it used for?

Hi. I'm trying to translate the SHT30 library for stm32l0. But I could not understand and translate the "IIC_Init" part of the code. I didn't understand the init part, I couldn't translate it and it only gives a line there What do you think are the o...

LSM9DS1 WHO_AM_I REGISTER (0x0F)

Hello, I have difficulties to get value of 0x68(IMU) and 0x3D(Magnetometer) from LSM9DS1 WHO_AM_I Reg 0x0F. I did on custom made board with STM32L083RZ and use I2C communication to LSM9DS1. I am using I2C3 PortC pin 0 and pin 1. The SDA&SCL are both ...

I2C implementation between STM32 MCU and sensor using Low-Layer API

Hello,Could you share any examples of I2C communication implementation between STM32L011 MCU and temperature sensor using Low-Layer (LL) API? I am trying to read temperature values from temperature & humidity sensor HDC2080. I found a library for thi...

VL53L1X does not boot.

I recently purchased VL53L1X ToF laser ranging sensor and for the last couple of weeks I am trying to make it work. Based on reference schematic from the datasheet I built the following setup:Using STM32L011 uCU, ULD API and LowLevel I2C libraries ...

Algobuilder with ArmCortex M0+ Nucleo

Hi!We are using AlgoBuilder with the NUCLEO-L476RG and it is working pretty nice. We wanted to try out our AlgoBuilder application on an Arm Cortex M0+ board to evaluate power consumption and behaviour. From what I saw from the documentation it seems...
