    hi,could i use the function BSX_S8 bsx_get_gyrocordata_rps(ts_dataxyzf32*) in BSXLITE fusion library ?

    and i find that ts_dataxyzf32* is  in BsxLibraryDataTypes.h.

    /*struct ts_dataxyzf32*/
    /*brief 3-axis data as F32*/
    typedef struct{
    BSX_F32 x; /**< x-axis data */
    BSX_F32 y; /**< y-axis data */
    BSX_F32 z; /**< z-axis data */
    }ts_dataxyzf32;

    but i find other functions that  also use 'ts_dataxyzf32*'in BSXLITE fusion library,such as BSX_S8 bsx_get_acccordata(ts_dataxyzf32*);

    how can i distinguish between them?

    could i use them directly?

    thanks

    Yes, you can use that function to get corrected gyro data from BSX lite lib.

    ts_dataxyzf32 is just a data type defined for lib output which contains x / y / z data.  so it is the datatype used as gyro and acc output. 

    you can easily distinguish them by their name. 

    bsx_get_gyrocordata_rps is function to read out gyro data in unit of rad per second

    bsx_get_acccordata is function to read out acceleration data

    thanks

    i could see the acc data  now.

    but the data seems to be too large ,maybe overflow .

     the acc sensor is 14 -bit.

    i can not understand why the data is too large.

    i use the function as follows:

    bsx_get_acccordata(&bmf055_acco);

    bmf055_acc_data_int_x= conv_scale_float_int16(bmf055_acco.x, QUAT_SCALING_FACTOR);//QUAT_SCALING_FACTOR=1

    Yes, the acc data is 14 bit but the BSX arleady convert the acc data as physical unit (m/s2) and use 16 bits when you call that funciton.  

     

    hi,so what is the output m/s range?

    thanks.
