Output data from LSM6DS3 appnote doesn't make sense
We're evaluating the LSM6DS3. Its appnote (D027415 Rev 5) has table 20 on page 39, "Output data registers content vs. angular rate (FS_G = +/- 250dps)". Zero is zero, no problem there. The other examples are 100 and 200 dps. Let's use the positive va...
FSM#10: How to… test your FSM – WRIST TILT detection, further algorithm examples
This example describes how to set up a finite state machine to enable the built-in detection of a WRIST TILT action. The picture here below shows the steps of the dedicated FSM. WRIST TILT FSM allows you to check when your wrist tilts, e.g. in case o...
LIS3DSH. Data for X, Y, Z does not change.
Started working with LIS302DL. Then took the LIS3DSH. The program is the same. After starting LIS3DSH, it gives correct readings along the axes, but after a few seconds of work, the data becomes permanent. The time to failure varies from a few second...
LSM6DSO SPI communication problem
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...
Which is g calibration value?
Hi to all, which is factory calibration value for g for MEMS accelerometers?Is this value the same for all accelerometers (I suppose)?Thanks.
FSM#9: How to… test your FSM – Motion detection, further algorithm examples
This example describes how to set up a finite state machine to enable the built-in detection of a Motion action. The picture here below shows the steps of the dedicated FSM. Motion FSM allows you to detect the movement of your device from a steady st...
SensorTile Drivers and Implementation
Posted on March 20, 2018 at 11:21Hello All,I am having a a bit of an issue working with my SensorTile kit. I am able to get the demo apps working and so on, but I now want to start on my own project.For the moment I have just tried to set the MCU up...
BMI160 pins 2 and 3 - safe to connect to ground?
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...
FSM#8: How to… test your FSM – Free fall, another algorithm example
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...
