not work "P-NUCLEO-LRWAN2"

I bought "P-NUCLEO-LRWAN2" last week.I read the manual and try it.The gateway is well. but the sensor device as "I_NUCLEO_LRWAN1" is not working.first. I think the device involved a default binary. so, I connected sensor device with my PC. I opened t...

Hello, my goal is to log (H,P,T) data to the SD 8GB I've mounted locally on my cradle FP-SNS-ALLLMEMS1 V. 3.10 MCU L476, correctly dialoging with my Android App ST BLE Sensor. How to write log data to the SD?

If I try to use the Data recorder app, available among the Example Apps, the FP-SNS-ALLMEMS1 Sensor is no more found (there is a message about ST BLE Sensor time out).

Roll pitch error when the sensor is rotated 360 degrees of yaw

Hello.I am using lsm6dsl to find the angle.When I turn the yaw rotation 360 degrees at that time, I have an error on the roll and pitch.Now, based on the angle (XY) determined by the accelerometer, I am trying to determineWe are trying to find the an...

How ACC reading with i2c communication?

Hi,I am using STM32F407 DİSCOVERY. I am trying to internal accelerometer(LIS3DSH) reading with I2C communication because my teacher asked for this but everyone ACC reading with SPI communication. I wonder if it is not read with ACC (LIS3DSH) I2C or a...

How to use TIM with SPI to acquire audio data from MEMS microphone

Hello :smiling_face_with_smiling_eyes: I'm using the microphones on the X-NUCLEO-CCA02M2 Digital MEMS microphones expansion board based on MP34DT01-M for STM32 Nucleo. This card is plugged on nucleo stm32h743zi2My problem is that I have to interface ...

Synchronize timing ODR for multiple accelerometers acquisition - IIS3DWB

Hello,Is there a way to synchronize the timing acquisiton time for multiple IIS3DWB accelerometers ? (synchronize the ODRs of each accelerometers)It seems there is no triger PIN to start the acquisition so all accelerometers could be synchronize ...I...

Hi, We are planning to use MP34DT05-A MEMS microphone from STMicro. Our application frequency range is 20Hz to 20KHz. The data sheet shows frequency response only up to 10KHz. Is this part suitable for application up to 20KHz, if not what is the max freq?

I am having a issue running LIS2DW12TR in 3V environment, the part is working fine at 1.8V once i plug the device to 3V supply it will start getting high current and some times burn.

we already cut trace the pin SDO connected to GND but still same issue, INT1&2 not connected physically by flipping MCU pin so it will not connect, the most ideal for our application is run the accel in 3V supply so we do not need a translator or any...
