Cannot I^2C to ST-nucleo-IKS01A3 in a normal I2C setting

Hi I recently bought a IKS01A3 and want to do research related to human activities. I already have a nucleo-wb55 with me so basically I just connect them via arduino uno V3 ports and willing to set up I2C communication between those two boards. I kno...

Magnetometer (model LIS2MDL) getting strange readings for not so high magnetic fields. What is going on?

As you can see in the picture, the higher part of the sinusoid signal is getting wrecked in the highest part, but it appears in the lower part (so the information is still there).This happens when the magnetic field is strong enough (We are putting a...

Resolved! Will the LIS2HH12 operate properly with Vdd_IO = 0V and Vdd = 3.3V ?

We are looking at using the LIS2HH12 in a design where the connected MCU is powered off and the LIS2HH12 remains powered on. We plan to use the LIS2HH12 in I2C mode so CS will be High. Will cycling Vdd_IO from 3.3 to 0 to 3.3V generate spurious I2C s...

IIS3DWB XYZ accel operation in I2C mode and thresholds for wake up and activity interrupts.

In I2C mode for the IIS3DWB device the datasheet says it only support single axis mode because I2C is too slow to get the data. I want to use I2C mode to configure either wake up or activity thresholds for all 3 axis and then configure the interrupt...

hi, im using LSM9DS1 in my new board. i can get the address when i use i2c scanner code, but when i try to read from it, there is no data coming in either from gyro/accelero or magnetometer.

here is my circuit for the LSM9DS1i used the code from sparkfun breakout moduel to test the board. i can get the data from their board, but not my board.

Is there a Linux driver for iis2dlpctr available? Or is there an update of st_accel_i2c.c with iis2dlpctr? Or include st_accel_i2c.c an compatible type ? What i must include for iis2dlpctr into the dtb file ".compatible = "st,...",

How to integrate LSM303AGR in STM32CubeIDE with STM32L4

Hey all! I'm doing a client project where I'm integrating an LSM303AGR on a custom board. I've included the XCUBE-MEMS package into STM32CubeIDE, and selected the LSM303AGR and set the I2C settings in the platform settings. This gives me LSM303AGR.C/...

Failed to access LIS2DH12 motion sensor WHO_AM_I register via MCU STM32F412CEUx (UFQFPN48).

PB3 and PB10 are enabled as I2C2_SDA and I2C2_SCL to connect to LIS2DH12 SDA and SCL, the i2c2 code is generated in STM32CubeIDE v1.6.1.PB3 and PB10 have pull-up resistors.LIS2DH12 CS and SD0 are connected to Power Supply 3.3V. The address for it is ...

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....

Resolved! Why do my I2C HAL commands to the LSM303AH not work?

When power is applied to the STM32L476, 3.3 v is also applied to the LSM303AH pins2 CS9 Vdd 10 Vdd IOThese commands work:MX_I2C3_Init(); Goes to code created by CubeMX HAL_I2C_GetState(&hi2c3); ...
