Posted on January 13, 2014 at 18:35All the example code I've seen reads the acceleration and magnetic field values by polling the appropriate registers.For example:x.l = i2c_read(OUT_X_L_A);x.h = i2c_read(OUT_X_H_A);y.l = i2c_read(OUT_Y_L_A);y.h = i...
Posted on November 27, 2013 at 15:26Hi,I need to read the accelerometer data from LSM303DLHC. I use the STM32F401 Discovery board and the ''stm32f401_discovery_lsm303dlhc.c'' library.I read carefully the datasheet, especially the section 7.1 in page...
Posted on January 14, 2014 at 11:04Hi,I would like to know : how did you calculate the L3GD20 sensitivity (LSB/dps) in the example?#define L3G_Sensitivity_250dps (float)114.285f /*!< gyroscope sensitivity with 250 dps full scale [LSB/dps] ...
Posted on January 13, 2014 at 10:10Hello, In the iNemo Engine Lite Version 1.2.0 (FW V.2.3.0) when analizing the EKF Prediction state I came to the conclusion that the quaternion update is not using the same mathematical function defined by the pMa...
Posted on December 23, 2013 at 15:01I would like to configure both the CS43L22 Audio DAC and the LSM303DLHC MEMS accelerometer to be used simultaneously. From what I have seen on the documentation, it seems that both of these devices are connected t...
Posted on December 13, 2013 at 19:45If the LIS3DH range is set to +/- 2g, how does the chip behave if acceleration exceeds 2g's? Do the axis outputs limit, wrap around, go to some fixed value, etc?
Posted on December 12, 2013 at 18:48hi, I use LIS3DSH and a problem appear sometime at init, in fact we catch false value from chip (offset error on x axis). Only offset is not correct (same offset value in case of pb). SPI bus reading is correct , ...
Posted on December 06, 2013 at 12:00Hi, I don't know, the interrupts work. I have the testcase attached. Here is the logged sequence: BEGIN: STAT_REG = 0 .. STAT_REG = 0xF // here should come the Int, shouldn't it? .. STAT_REG = 0xFF // Overflow, ne...
Posted on November 06, 2013 at 17:41Good morning, I am having some trouble in working with the magnetometer with the 12 and 8 gauss range. I am using an SPI communication. All the data from accellerometer and gyroscope are correctly as well as fo...
Posted on December 19, 2013 at 20:05Can anybody point me to any additional reference material on the LSM9DS0. Such as any reference designs and source code. Interested in proper implementation of read/write sequencing. Thanks. #lsm9ds0-referen...
