Resolved! IMP23ABSU vs MP23ABS1

Does anybody know if there is any difference between these two MEMS Microphones. The IMP23ABSU does have some Ultrasonic characteristics, but my understanding is the MEMS mics would have ultrasonic bandwidth anyway.Thanks

PDN impedance recommendation? ASM330LHH

Hi, I'm optimizing the decoupling capacitors of the board using PDN analysis with ansys siwave tool.And I need to set the requirement for the IC.Do you have a recommendation for that?For example, the IC needs: 0.1ohms between 0 and 10MHz, then 0.2ohm...

Resolved! STWINKT1B STREAMING USB

Hi,I bought the STEVAL-STWINKT1B hoping to be able to store and plot real-time data from my accelerometer, both in the time domain and in the frequency domain (performing FFT) for the purpose of developing my project. I bought it thinking that it wou...

Vibration sensor sleep mode

Hi,We confirmed that it is due to vibration sensor (IIS3DWBTR) only because when we removed sensor IC and tested remaining board the consumption was 7.4uA with micro controller (STM32) , memory also. But after placing vibration sensor and making it i...

LIS2DH12 accelerometer values suddenly close to zero (-4, 0, 4)

Posted on November 14, 2017 at 21:08Dear allWe are using LIS2DH12 accelerometer in our product. We are juat about to launch the production and sales when we faces a weird problem.Suddenly the accelerometer starts reporting values like 0, 4 and -4, i...

Resolved! How to display the float value in Cube IDE .

 I am using Sprintf, but I cant see the number in UART LPS22HH_pressure=LPS22HH_GetPressure();   sprintf(result,"%4.2f", LPS22HH_pressure); // @suppress("Float formatting support")I have also tried %g

IIS3DWB uses ~275uA in Low power mode - not 5uA-16uA

I have an issue with current consumption of a IIS3DWB using the STEVAL-MKI208V1 kit.I have previously discussed it in this issue, but I've traced (i hope) the issue to the VDDIO pin.I'm using a STM32WB55CEU6 as SPI master.To measure current I'm using...
