ROUND MEMORY

Round Memory Averaging for Realtime Datasampling and processing

Usage

1. Initialize memory space by:

    RoundMemory<float> sensorReadings = RoundMemory<float>(100, 0);

2. Append new sensor readings to memory space using:

    sensorReadings.append( sensor.getReading() ); // replace argument with new reading to append.

3. Use avg() to get the average of the samples of last 'size' readings.

    Serial.println( sensorReadings.avg() ); // returns average of readings.

4. RoundMemory.append() function returns the change in average before appending and after appending.

    float delta = sensorReadings.append( sensor.getReading() );

    // is the same as:
    float u = sensorReadings.avg();
    sensorReadings.append( sensor.getReading() );
    float delta = u - sensorReadings.avg();

Memory usage

4 + (size * sizeof(datatype T)). increases linearly as size is higher. Higher the size, more cpu cycles will be used to perform avg();

Use conservative-branch for low memory application, and for much higher performance.
