LSM6DSO FIFO incorrectly fills with timestamp data when in Bypass-to-fifo mode with sensor hub enabled
Hello,I am trying to implement some functionality that will fill the LSM6DSO(32)s FIFO buffer when a severe impact is detected. This is done by utilising the wake up interrupt with the slope filter enabled, when the sensor is in bypass-to-fifo mode. ...
LIS2DW12 stationary/motion INT pin not automatically deasserted (reset) after 1/ODR interval
Hi.I'm working with LIS2DW12 and setting it to work in stationary/motion detection. The Wake-up interrupt is driven to INT1 pin. However, when observing the signal of INT1 with logic analyzer, when the sensor is moving, having acceleration higher tha...
Resolved! temperature impact over gyroscope zero-level offset
Hi,I'm using the LSM6DS33 MEMS and found that in different temperatures the zero-level offset of the device gyroscope changes significantly.I recorded several recordings while the device is static, and found that consistently when the temperature inc...
Resolved! Problem programming the sensortile with Nucleo
I have recently got a brand new Sensortile and a nucleo L476RG. I checked if the tile was working by connecting the tile to the cradle expansion board (STLCX01V1) and using the bluetooth app from ST (STBLESensor). The system worked and I could view d...
Resolved! I have the IIS3DWB configured in single Axis mode and I keep seeing a clear peak in the spectrum at 9.5kHz even when the sensor is stationary. I'm not sure why this is happening given that i have also configured LP2 to ODR/4.
Please see attached a screenshot of the spectrum and a snippet of my code. thanks
Resolved! Always getting ERROR when reading MLX90393 data.
Hi,I try to use MLX90393 with my STM32-F4 DISC board on SPI2. I can communicate with it, read and write non volatile memory, he responds to me.The steps that I'm doing are:Go to Single Measurment mode ( 0x3F )Send Read Measurment command ( 0x4F) Read...
How to get the LSM9DS1 recommended power-up sequence?
Hi, I am reading the datasheet of LSM9DS1 and it says that there are two times (rise and wait) you should respectI was thinking in a sequencer IC but if we see the schematic of the LSM9DS1 evaluation board (STEVAL-MKI159V1) it does not use any kind o...
Resolved! Driving an ILI9163c based display with the NUCLEO-F446RE (+library questions)
As per the question I'm trying to run a ILI9163c based display on the NUCLEO-F446RE. I'm using this library: (https://github.com/Spirit532/ILI9163C_STM32_HAL_DMA). My questions are:The library tells you to put DMA into circular mode. However, after e...
Resolved! How to calibrate tap sensing (LSM6DSM)
Hi, I have been able to get this sensor working, but the issue is that tap/double tap is really, really insensitive. Maybe its the plastic case of the unit, I do not know. I did the tap detection as in example:https://github.com/STMicroelectronics/ST...
