ArduinoLibs Documentation

This distribution contains a bunch of libraries and example applications that I have made for Arduino, covering a variety of tasks from blinking LED's to LCD's and RTC-based alarm clocks. They are distributed under the terms of the MIT license, with the source code available from github.

For more information on these libraries, to report bugs, or to suggest improvements, please contact the author Rhys Weatherley via email.

Freetronics LCD Shield

• LCD class to manage the extended features of the Freetronics LCD shield.
• Form and Field classes to build simple property sheet UI's on LCD displays.
• Hello World example for the Freetronics LCD shield.
• Form example for LCD displays.

Freetronics Large Dot Matrix Display (DMD)

• DMD class to manage the initialize of the display.
• Bitmap class to manage drawing to in-memory bitmaps and the DMD display.
• Demo that shows off various bitmap drawing features.
• RunningFigure example that demonstrates how to draw and animate bitmaps.

BlinkLED Utility Library

• BlinkLED class that simplifies the process of blinking a LED connected to a output pin.
• ChaseLEDs class that simplifies the process of performing a LED chase over several output pins.
• Blink example of using BlinkLED.
• Cylon example of using ChaseLEDs to simulate the Cylon eye effect from Battlestar Galactica.
• StarTrek example for lighting a starship Enterprise model kit.

I2C Utility Library

• I2CMaster abstract class that provides an improved API for implementing an I2C master.
• SoftI2C class that implements the master side of the I2C protocol in software on any arbitrary pair of pins for DATA and CLOCK. This class supports both 7-bit and 10-bit I2C addresses.

Realtime Clock Library

• RTC class that acts as a base for all realtime clock implementations, including support for configuring alarms and storing clock settings. The default implementation simulates the time and date based on the value of millis().
• DS1307RTC class that talks to the DS1307 realtime clock chip via I2C.
• DS3232RTC class that talks to the DS3232 realtime clock chip via I2C.
• Alarm Clock example that uses the DS1307 or DS3232 realtime clock and the LCD library to implement an alarm clock.

Other

• Melody plays a melody on a digital output pin using tone().
• Power saving utility functions
