LSM6DSM loses its configuration.

LSM6DSM loses its configuration when another chip in the board is turned on. SIMO pin goes up for 1.5ms when it happens, with a voltage of 2.2V even though the accelerometer is fed with a 2.8V supply voltage. I do not see a glitch below 1.8V which co...

LIS3DH ADC1 input troubleshooting

I've implemented a new low power design using LIS3DH, and I had in mind to use ADC1 input to monitor the battery voltage and ADC3 to monitor temperature.I succeed to properly read all three accelerometers axis as well as temperature. On the ADC1 inpu...

Question about LIS3DH FIFO operation

Hi,I want to configure the LIS3DH working with FIFO mode and OVERRUN interrupt on INT1. So, once the interrupt occur, MCU will read all data from FIFO. by reading the datasheet, I am a little bit confused for FIFO overrun behavior. On the page 22 of ...

How can I get the quaternion matrix Q directly from LSM6DSO?

I download the document from your website, it shows how to rotate the coordinate, while the function it uses directly get the quaternion matrix Q which I cannot read from the board, can some one told me how to get this Q data? Attached is the documen...

Configure LIS3DSH state machine to detect angle change?

I've used the LIS3DSH state machine to set the INT1 interrupt high when a certain acceleration threshold is exceeded. However, I'd like to use the state machine to detect a change in orientation.For example, I'd like it to set the interrupt high whe...

Fall detection not working with STM32F401RE & IKS01A2

HiI ​ expected & need to detect human(senior or kid) falling to ground not free falling.When I tested with the pre-built binary named "STM32CubeExpansion_MEMS1_V6.2.0\Projects\STM32F401RE-Nucleo\Applications\IKS01A2\FallDetection\BinaryFallDetection....
