Arduino library for the Parallax 27979 serial display
|
|
|
|
|
|
|
|
|
|
## Description
|
|
|
|
|
|
|
|
|
|
The library is essentially a wrapper around a Stream, typically Serial,
|
|
|
|
|
Serial2 (3,4..) or newSoftSerial or equivalent.
|
|
|
|
|
This stream is given as parameter in the constructor.
|
|
|
|
|
|
|
|
|
|
The library implements the **Print** interface to print integers
|
|
|
|
|
floats and strings and all printable types.
|
|
|
|
|
|
|
|
|
|
The library does not keep any state information, it only implements a few
|
|
|
|
|
methods to make working with it easier.
|
|
|
|
|
These methods are quite trivial.
|
|
|
|
|
|
|
|
|
|
* **on()** switch display on
|
|
|
|
|
* **off()** switch display off
|
|
|
|
|
* **clearHome()** clear the display
|
|
|
|
|
* **backlightOn()** enable the backlight
|
|
|
|
|
* **backLightOff()** disable the backlight
|
|
|
|
|
|
|
|
|
|
**Movement**
|
|
|
|
|
* **cursorLeft()** move cursor
|
|
|
|
|
* **cursorRight()** move cursor
|
|
|
|
|
* **lineFeed()** idem
|
|
|
|
|
* **formFeed()** idem
|
|
|
|
|
* **gotoXY(x, y)**
|
|
|
|
|
|
|
|
|
|
**Sound support**
|
|
|
|
|
* **octave(octave)** octave = 3 4 5 6 7
|
|
|
|
|
* **duration(duration)** duration = 1 2 4 8 16 32 64
|
|
|
|
|
* **play(note)** note = 0 1 2 3 4 5 6 7 8 9 10 11 0=A 1=A# etc
|
|
|
|
|
* **noSound()**
|
|
|
|
|
|

|
## Support Parallax 27976 & 27977
|
|
|
|
|
|
|
|
|
|
Although not tested, the functions should work with the
|
|
|
|
|
Parallax 27976 and 27977 displays too.
|
|
|
|
|
|
|
|
|
|
