Init Method​

void initAll(void); Init data

Add Device​

int add_device(char *serial)

Delete Device​

int delete_device(char * serial)

Get Original Data​

get_eeg_info_t Split_data_frame(char *str)

Return:

typedef struct
{
    unsigned int frame_dect_ok;        
    int frame_index;
    unsigned long  group_count;        

    double AF7_eeg_data[50];            
    int AF7_leadoff_flag[50];          

    double AF8_eeg_data[50];            
    int AF8_leadoff_flag[50];           

    int have_4sec_time_flag;            
    int time_flag_postion;             
    long time_counter;                  
} get_eeg_info_t;

Get Indicators from Algoithm​

algorithmTarget get_algorithm_result(double data_raw[58],int index) data_raws stands for original data, index 0-28 are for channel AF7 and index 29-57 are for channel AF8. index stands for the index of the array.

Return:

typedef struct {
    double mindfullness; // Mindfulness
    double focus; // Degree of concentration
    double emotion;  // Degree of mood
    double stress; // Degree of pressure
    double fatigue; // Degree of fatigue
    double relax; // Degree of relax
    energyName energy; // Original data
    int isValid;
    int sqd[2]; // signal quality indicators from AF7 and AF8 (signal description: 0 stands for good signal quality，1 stands for poor signal quality)
    int sqdValid;
} algorithmTarget;
typedef struct {
    double alpha;
    double beta;
    double theta;
    double delta;
    double gamma;
}energyName;

Get Conherence Indicator​

double get_alg_coherence(double * indata,int len)

Get 4 Indicators of mindfullness radar map​

mindfulnessScore getMindfulnessScore(double * array,int length)

typedef struct{
    int stability; // Stability
    double potential; // Poential
    double percent; // Percentage
    int score;// Sore
} mindfulnessScore;
