LSM330 Bits in Data Output

Posted on October 08, 2014 at 14:09Hello How many bit does the data output of the LSM330 have? I can't find it in the datasheet. The register is 2x8 bit long, but are all bits valid? Regards Daniel #lsm330

LSM303DLHC drdy interrupt

Posted on October 08, 2014 at 09:04 I have a STM32F3-discovery board, and I have set up a little test. It just captures ALL input on GPIO3 and count them by channel. Then every seconds, I have a breakpoint with which I look at the numbers, ...

LIS3DH sensitivity

Posted on September 02, 2014 at 17:05The sensitivity for this accelerometer is listed as 1mg/digit at +/-2g FS.  This brings up a few questions.  First, is a ''digit'' and LSB?? Second, at 16 bits, a LSB would be about 0.06 mg, not 1.0 mg.  There's ...

ECB Land pattern for LIS3DSH?

Posted on September 10, 2014 at 19:17Greetings -The LIS3DSH spec sheet says: ''Land pattern and soldering recommendations are available at www.st.com.''So far, I've not been able to find the info. Could someone please point me in a useful direction?...

characteristics of LPS331AP - Temperature Sensing

Posted on May 22, 2014 at 09:08Is there more detailed spec on the temperature sensing of this part? In the data sheet it states +/- 2C from 0-80C. Is there a range where it is tighter?We are finding that room temp (~25C) we are on the high end +1.4C...

Noise Characteristics?

Posted on October 04, 2014 at 21:33How can we learn the noise densities for many of ST accelerometers? I am currently using analog LIS344ALH in my design, since it has a low noise density stated in datasheet. If intended to use a digital/SPI interfa...

LSM330DLC problem

Posted on July 17, 2014 at 17:33Hi guys,I'm using the LSM330DLC on a weareable device, but while testing I noticed that while measuring the gravity I get values on Z axis around 1380 counts (0x0564 hex raw data coming from the ic).The configuration ...

How much current consumption when enable LIS3DH's interrupt

Posted on September 25, 2014 at 13:32if LIS3DH interrupt output floating or connect to very high impedance device, what is the current consumption when interrupt is enable? Is the device consume 100 over uA when interrupt is enabled? #lis3dh #li...

LIS3MDL Data Registers Not Updating

Posted on September 24, 2014 at 20:38Hello,I recently received a LIS3MDL board for evaluation.  After successfully implementing communications over I2C and receiving good data, it recently started misbehaving.  I am unable to read any data from the ...
