Masahiro Furukawa / Mbed 2 deprecated MPU-9250-MagSens_M-Series

2Chx3dof Magnetrometer supported M-Series Random Sequence Generator Servo Control

Dependencies:   mbed

Sampling Frequency

Sampling Frequency in main.cpp

#define SampleFreq     200   // [Hz]

Auto Stop Setting

Auto-stop Timer 15sec after

    // auto-stop when 15sec after
    if(smpl_cnt>3000){stop_dump();}

The number of 3000 means Sample Count. The number is given by SampleFreq[Hz] * Auto-Stop Time [sec].

M-Series Random Sequence

M-series Random Update Term in main.cpp

// M-series update flag
#define  M_TERM  200;

Unit is sample count.

cf.) 200 equals to 200 [samples] which equals to 1 [second] where SampleFreq = 200 [Hz}.

See above.
