Arduino Buffer

This is a arduino library that helps to buffer values.

Instalation

1. Download the master branch from github.
2. Unzip the file on the arduino library folder
3. Restart the Arduino IDE

Features

• Get buffer averages

Getting Started

Create buffer instance

Buffer b = Buffer(length, init);

or

Buffer b(length, init);

or

Buffer* b = new Buffer(length, init);

Constructor

Buffer(length, init) Create a new instance and clear the buffer. length: Buffer size, init: Initial value

Getters

• calcAverage() Calc the buffer average and return the result
• getAverage() Just return the buffer average
• getAt(index) Returns the buffer value by index
• empty() Check if the buffer average is equals the initial value

Setters

• fill(value) Fill the buffer with the value
• insert(value) Insert a new value to the buffer and calls calcAverage()
• clear() Fill the buffer with the initial value

Example

// Create a instance of Buffer
Buffer sensorBuffer(10, 0);

// Your sensor read function
void sensorRead(){
	// Get a new sensor value
	int read = readSensor();
	
	// Insert the new value on buffer
	sensorBuffer.insert(read);
	
	// Print the sensor average on Serial Monitor
	Serial.println(sensorBuffer.getAverage());
}
