Hello, i read the AN4650 application note for the LSM6DS3 accle+gyro and i tried to implement the sensor hub routine with a MAG3110, like the one in the examples but it doesn't seem to work, is there another application note or a sample code that i c...
This example describes how to set up a Finite State Machine to enable the built-in detection of e.g. the orientation of a phone screen (4D orientation). The picture here below shows the steps of the dedicated FSM. Basically, to get FSM output data yo...
Hello everyone. I recently designed a board, with stm32f303cbt6 MCU and MEMS audio sensor mp45dt02 which comes included with the stm32f407 disco board. I have a running configuration on the disco board, which captures mic data and sends it to the DAC...
Hi, I am using LSM303AGR reading accelerometer as well as magnetometer in the single mode. The problem is that sometimes I get wrong data and it seems like time between a single measurement request and measurement is changing. I could not find any de...
I’m trying to use the L3GD20 gyro to compute angular position from the angular velocity measurements returned from the gyro. Most of the time, everything works as expected. However, if I move the gyro in two directions (roll and pitch) at the same ti...
Before starting with your first Fine State Machine, it will be helpful to have a further look at the Unico tool. With Unico you can easily interact with your device, setting the desired configurations, reading and writing the registers, stream data a...
Two questions:(1) If I want to poll the status register instead of using interrupts, and don't want to use the FIFO, is the following initialization sequence sufficient? uint8_t cmd ; GYRO_IO_Init() ; // Enable Block Data Update and full scale = 2000...
Good morning,I am trying to read the WHO_AM_I register from LSM6DSO, but it doesn't respond as needed. I will attach a picture from signal analyzer (D0 is CS, D1 is CLK, D2 is MISO, D3 is MOSI). It looks like its respond is 0x50 instead of 0x6C. What...
The best way to start experimenting with the LSM6DSO is with the STEVAL-MKI196V1, a daughter board integrating the MEMS that will significantly hasten the prototyping phase as its schematics will show exactly how to port it to a final PCB. The board ...
Hello,i studied extensively the "sensor_hub_lis2mdl_lps22hb_no_fifo_simple" example so i can use the LSM6DS3 with an external magnetometer. There are 4 lines that i cannot understand, in the main example there is the code below /* * Configure LI...
