C++ (Cpp) TO_FREQ Examples

Example #1

File: gate.c Project: rdnelson/Hazzard

//Get frequency and update running totals
double getFreq(int gate){
    gettimeofday(&currentTime[gate], NULL);
    long long timeDiff = timeval_diff(&currentTime[gate], &lastTime[gate]);
    lastTime[gate] = currentTime[gate];
    // High pass to ignore first trigger when a car passes, and catch only
    // actual edges of the blink
    if (TO_FREQ(timeDiff) < MIN_CUTTOFF) {
        return 0;
    }
    //Running average calulation, 
    runningDiff[gate] = runningDiff[gate] + EXP_CONST * (timeDiff - runningDiff[gate]);
    //Don't divide by 0
    if (runningDiff[gate] == 0)
        return 0;
    return TO_FREQ(runningDiff[gate]);
}
