LSM303AGR accelerometer readings problem

Posted on April 19, 2017 at 14:25Hi all,I'm trying to interface a LSM303AGR, to get the magnetometer and accelerometer values in I2C.The component is responding well to whoami requests (both compass and magnetometer parts), I manage to get mag value...

LSM6DS3 Delay

Posted on April 19, 2017 at 23:28I'm using the LSM6DS3 to control a gimbal with a camera on it, and I'm noticing that my control is suffering due to delay in the system. I have configured the LSM6DS3 for an output datarate of 208Hz, with the fifo in...

''nano'' vs ''pico'' vs ''femto'' accelerometers?

Posted on April 13, 2017 at 13:39Totally new to ST accelerometers, I can see that they're grouped into what look like three 'families' -- nano, pico and femto. Is there a short explanation of the differences between those three families? A link to a...

LIS3DH: XYZDA on INT1 doesn't clear reliably

Posted on April 18, 2017 at 07:48I'm using an LIS3DH accelerometer. It is configuring properly and returning valid data when manually read at a fixed interval. Now I'm trying to switch to the use of its XYZDA signal that is emitted on INT1.I have al...

IIS2DH Reading FIFO

Posted on April 13, 2017 at 01:08With a 2g scale sampling @25Hz the FIFO fills with data and I am reading the contents up to the watermark. HR and LPen are disabled.With the Z-Axis pointing toward earth I get the following data for the X-Axis using ...

LSM303DLHC DRDY Behaviour

Posted on April 13, 2017 at 12:58The detailed behaviour of the LSM303DLHC DRDY pin (pin 9) is not elaborated upon in the datasheet.We have observed that it generates active low pulse but this is not detailed in the datasheet. What are the timing req...

IIS2DH Reading and Clearing FIFO

Posted on April 12, 2017 at 17:13I am moving to the IIS2DH from the LIS3DSH because it is end of life. I am having an issue with reading the FIFO. I can enable FIFO mode and it seems to fill and generate an interrupt on OVRN and WTM just fine, but t...

Magnetometer difference between LSM9DS0 and LSM9DS1

Posted on April 11, 2017 at 08:08 We are upgrading our IMU from a LSM9DS0 to LSM9DS1. However we are having issues with the magnetometer on the LSM9DS1. Even after min/max calibration it doesn't appear to give correct heading. We are aware tha...
