ASM330LHH - large gyro biases
Hello, We are using the ASM330LHH in a design and are seeing extremely large gyro biases (~250 deg/s). I am trying to figure out what may be causing them; here is some information on the experiment. We collect data while spinning our custom boards (w...
Interfacing MP34DT06 with STM32F401RE Sensor
Hi,I’m using the NUCLEO-STM32F401RE with the X-NUCLEO-CCA02M2 board, which has two MP34DT06 PDM microphones. I want to capture stereo audio using I2S2 and convert it to PCM using the PDM2PCM middleware in STM32CubeIDE.In AN5027 (page 18), a timer is ...
impacts of IIC error injection with IIS2DLPC
For special test case, that directed connected IIC's SCL(LUX_TILT_SCL) to GND and kept for 5mins, will this action hurt or damage IIS2DLPC?IIC worked with 100kbps.Work with IIC. We found that after this action/error injection:Sometimes, the sensor ca...
IIS2ICLX inclination
Hello, I'm looking for a very high precision inclination sensor. I found this IIS2ICLX. I have some questions on the specifications.1) What is the repeatability of the device?2) From the spec sheet, it might seem like the repeatability of the device ...
Reading ISM330DHCX with Nucleo Board (SPI3)
Hi,I am trying to read data from my ISM330DHCX using my STM32G491 Nucleo board over SPI3However, I am having trouble understanding the operation of this device, so I would like to explore the answers to the following questions:1) What is the most bas...
Resolved! Accelerometers comparison
Dear community,I am selecting an accelerometer to use in a project and I am looking for some advice.Essentially I am looking for the highest performance accelerometer (regarding noise) in the STM portfolio.The sensor requirements are: ~±2g scale supp...
Resolved! Best Wireless Data Collection Method for STEVAL-MKI109 + MEMS Sensors?
Hi everyone,I'm starting a project using the STEVAL-MKI109D motherboard with the following sensor adapter boards:STEVAL-MKI247A STEVAL-MKI240KA My main goal is to collect sensor data wirelessly for analysis, rather than being tethered to a PC with a ...
Check configuration on lsm6dso32
Hi! I inherited a project and we're seeing strange accelerometer values and I'd like to get a sanity check on my configuration. when Idle and flat, I see 1g on Z, 0g on X and Y. When my device is moving I see peaks on many axes beyond 1g, eg 2.5 on X...
LIS3DH Double interrupts detection
Hi ST guys,I played with the LIS3DH accelerometer options and don't really see difference in interrupts.Can you explain the differences between 6D and no 6D because as per my understanding of AN3308 the AOI + 6D option is position detection which is ...
