Dash.ino

Arduino Library for RAKWireless Dash Internet Button

Features

This lib brings functions for:

• Keep state of Keys
• Key event handler
• Keep state of LEDs
• LEDs brightness via PWM (8 levels)
• State & Color constant definitions
• Battery state
• Reset, Shut off

Installation

To install this library, just place this entire folder as a subfolder in your Arduino/lib/targets/libraries folder.

When installed, this library should look like:

Arduino/lib/targets/libraries/Dash              (this library's folder)
Arduino/lib/targets/libraries/Dash/Dash.cpp     (the library implementation file)
Arduino/lib/targets/libraries/Dash/Dash.h       (the library description file)
Arduino/lib/targets/libraries/Dash/keywords.txt (the syntax coloring file)
Arduino/lib/targets/libraries/Dash/examples     (the examples in the "open" menu)
Arduino/lib/targets/libraries/Dash/README.md    (this file)

Development

After this library is installed, you just have to start the Arduino application. You may see a few warning messages as it's built.

To use this library in a sketch, go to the Sketch | Import Library menu and select Test. This will add a corresponding line to the top of your sketch:

#include <Dash.h>

To stop using this library, delete that line from your sketch.

Geeky information: After a successful build of this library, a new file named Dash.o will appear in Arduino/lib/targets/libraries/Dash. This file is the built/compiled library code.

If you choose to modify the code for this library (i.e. Dash.cpp or Dash.h), then you must first 'unbuild' this library by deleting the Dash.o file. The new Dash.o with your code will appear after the next press of "verify"

Good to know

Default functions

1. Press Key2 longer than 5sec to reset
2. Press Key4 longer than 5sec to shut off (press any key to restart)

Key event implementation

• Interrupt not possible as now all keys support it
• Instead using a Timer 'polling' current keys
