We are using the LSM6DSL chip in SPI mode with the FIFO_CTRL5 and the CTRL1_XL registers set to 26Hz.The gyro is not used. CTRL6_C's XL_HM_MODE is set to '1' to disable high performance mode.When we are not using the LSM6DSL we set both the FIFO_CTRL...
I interfaced LSM9DS1 with TI micrcontroller TMS320F28035 with I2C protocol. The LSM9DS1 is SDO_A/G pin is pulled low, so that it can be addressed with 0x6A. But what I observe is..Whenever I power the board up, it does not respond with 0x6A and respo...
I'm using a LIS2HH12 accelerometer. I have discovered that when setting a threshold value, the negative threshold is half of what I expect. For instance, writing 0x01 to a threshold register I expect the threshold to be 8mg. This is true for positive...
--- More detail about MotionAR library ---The library is based on accelerometer data only, and requires a data sampling frequency of 16 Hz., and can to distinguish among the following activities: stationary, walking, fast walking, jogging, biking, dr...
I'm using the device in STREAM mode, with BDU=1.The datasheet says that PRESS_OUT_H must be the last read (enables an update).In one of my experiments it appears that it's actually a read from TEMP_OUT_H that causes an update.I've also noticed that s...
Hi,I am using a LSM9DS1 IMU on a custom PCB for the development of a dead reckoning feature.First step is quaternion calculation, and in order for this to be precise and reliable, sensors data have to be too. However, I'm having issues with the magne...
I have a SensorTile kit, right out of the box. STEVAL-STLKt01V1. With the ST BLESensor app on iOS, I can connect to the SentorTile and get temperature, etc. When I try to request a license for any of the libraries, the wizard forms an email to op...
I've done a lot of testings with two IIS3DHHC and everything seems fine. Suddenly one of the IIS3DHHC seems to lost the factory calibration. Is this possible? A lot of the tests have been done below freezing point -10C degree.In our solution, the Vdd...
I want to measure the tilt angle with an accuracy of +/-3°, with the IIS328 accelerometer. The datasheet states that the sensitivity varies between 0.9...1.1 mg/digit. Does this variation also apply between the axis, so that e.g. X-axis can have sens...
Hello,right now I am struggling on implemeting the two buildt in MP34DT01 MEMS microphones on the B-L475E-IOT01A1 eval board while using the existing Cloud Generic Example Code. I think my biggest problem right now is to get teh DFSDM running as I ge...
