LSM303D data synchronization

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...

CS43L22 and LSM303DLHC

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...

Behavior of LIS3DH past range limits

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?

LIS3DSH - error offset

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 , ...
