Posted on November 30, 2013 at 16:19 I've just read the thread: Data output format of the LSM303DLHC the accelerometer data is left�?justified, in normal mode, the data is in 12�?bit representation which means the lowest 4 bit in LSB are always 0s Is this true also for the H3LIS331DL? In the LIS331DLH_GetAccAxesRaw of your API, all values are shifted by 4. regards, Steffen

Posted on December 05, 2013 at 15:58 Hi, What's about the datasize? The datasheet states 16-bit data output. regards, Steffen

Posted on December 11, 2013 at 16:04 Hello Steffen, Yes you are right, the datasize is the same as the displayed on the datasheet, having the last 4 LSBs zeroes due to the 12bit data representation. I hope this answers your question!! Thank you, Thiago Reis

Sorry, but I don't agree.
On page 1 in the datasheet, you write 16-bit data output On page 30, it is stated: The value is expressed as two's complement On page 9 : Sensitivity 12-bit-represantation What would mean literally: 0xFFF - 0x7FF but not 16 Bit, or 0xFFF0 - 0x7FF0 or so. Please work your datasheet out so, that the designer can see the main points clearly and fast. Same for interrupts and so on. regards, Steffen
