Enable vibrometer in STWINKT1B
Hello Everyone,In STWINKT1B, I need to enable the IIS3ZDWB sensor (vibrometer) and should be able to measure vibration of the given object with my phone via Bluetooth but the ST BLE Sensor Classic app is only showing the environmental parameters.Can ...
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...
Resolved! LSM303AH -1G/1G Unexpected Output, Less than 90 degrees
Hello,I am having issues with my acceleration data being output from my LSM303AHTR. I have configured it for 2G Full scale making the "sensitivity" 0.061mg/lsb.I have tested two LSM303AH chips on two of our custom PCBs. I am getting similar results o...
How calibrate 2 magnetic sensors concurrently with MotionMC library?
I would like to calibrate 2 magnetic sensors concurrently with MotionMC library. However, the functions from the library for MotionMC_Initialize, MotionMC_Update and MotionMC_GetCalParams do not need inputting an ID. If calibrate 2 sensors in the s...
IIS2DH FIFO stream mode configuration issues
HiI am using an IIS2DH accelerometer and set up FIFO. The configuration sequences are following the IIS2DH example in Github, see below// 25Hz, Low-Power Mode Disabled, XYZ enabledACC_Write_Command(IIS_CTRL_REG1, IIS_CTRL_REG1_INIT_25HZ);// High-Pass...
