The BMI160 spec sheet says pins 2 and 3 are high impedance when the secondary I2C interface is not being used. The spec sheet also *implies* that the secondary I2C interface defaults to disabled upon a power cycle. The question is, can pins 2 and 3 b...
This example describes how to set up a finite state machine to enable the built-in detection of the Free Fall. The picture here below shows the steps of the dedicated FSM. The algorithm is able to detect the free fall of an object generating an inter...
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...
