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...

Application note for LPS25H?

Posted on March 13, 2014 at 00:22I am interested in the LPS25H MEMS barometer chip, but I am having a hard time figuring out the footprint of the HCLGA-10L package. Here is what is called out in the datasheet: I cannot decipher from his what the dim...
