Posted on May 07, 2013 at 18:05We have two LSM303DLHC on one board. Sometimes one of them appears to be stuck at -4096 on some axes. Even when I wave a magnet close to it doesn't change. The next day it's ok. The board was sitting on my desk all day...
Posted on May 03, 2013 at 06:25I am trying to get a gyroscope raw data using I2C. DEN_G is connected to MCU's GPIO and I set the register to use level trigger mode. I think I2C slave address is correct because when I read WHO_AM_I_G register I get 2...
Posted on April 23, 2013 at 19:05Greetings,I'm trying to bring up an LSM303DLHC and I'm having trouble getting any form of interrupt out of the device.I've taken an STEVAL-MKI119v1 and removed the MKI108v2 and jumpered it to my I2C bus. I have Vdd ...
Posted on April 12, 2013 at 14:42Is there a programming guide for LSM330? If there is one, could some one please post the link for that? #lsm330dl
Posted on April 12, 2013 at 11:06Hello,Accorting to datasheet, LIS331HH accelerometer don't have register WHO_AM_I. Is it possible to read identification data from 0xF register? What is identification value of LIS331HH? I need detect this accelerome...
Posted on April 08, 2013 at 22:36Hi all, I am new to the ST MEMS line, and recently purchased a few of the development boards to start testing (STEVAL MKI109V2, MKI120V1, and MKI115V1). I followed the manuals for assembly and installing Unico, and ...
Posted on April 08, 2013 at 14:28Hi, I am trying to read temperature values from OUT_ADC_3_H. I have also enabled BIT 6 and 7 in TempCfgReg and Block Data Update, BDU at CTRL_REG4(0x23). CTRL_REG1 is set to 100 Hz with value 0x57 running in normal...
Posted on April 01, 2013 at 16:19Hello.I use LIS3DH accelerometer with 4-wire SPI interface.I attached schematic of accelerometer connection (AccelSch.pdf).ACL_VDDIO = 3,3 VACL_VDD = 3,3 VOther ACL signals connect to microcontroller pins.R9A=R9B=R9C...
Posted on November 19, 2012 at 16:27Hi, I want to build an altimeter using LPS331AP sensor and after reading AN4159 I discovered that I should have software filter to have an accuracy of 0.02 mB required for altimetery. Do you know where to download...
Posted on July 31, 2012 at 12:14I can't quite work this out. Someone tell me if I'm crazy.LSM303DLHC datasheet is somewhat difficult to read here. I have CRB_REG_M set to 001, +/-1.3gauss, its most sensitive range. But all its axes are not equall...
