<b>"Out-of-Band" Commands</b>.
|
||||
Keyboards and keypads are the same device for NuttX.
|
||||
A keypad is thought of as simply a keyboard with fewer keys.
|
||||
In NuttX, a keyboard/keypad driver is simply a character driver that may have an (optional) encoding/decoding layer on the data returned by the character driver.
|
||||
A keyboard may return simple text data (alphabetic, numeric, and punctuaction) or control characters (enter, control-C, etc.).
|
||||
We can think about this the normal "in-band" keyboard data stream.
|
||||
However, in addition, most keyboards support actions that cannot be represented as text data.
|
||||
Such actions include things like cursor controls (home, up arrow, page down, etc.), editing functions (insert, delete, etc.), volume controls, (mute, volume up, etc.) and other special functions.
|
||||
We can think about this as special, "out-of-band" keyboard commands.
|
||||
In this case, some special encoding may be required to multiplex the in-band text data and out-of-band command streams.
|
||||
</p>
|
||||
<p>
|
||||
<b>Encoding/Decoding</b> Layer</b>.
|
||||
An optional encoding/decoding layer can be used with the basic character driver to encode the out-of-band commands into the text data stream.
|
||||
The function interfaces that comprise that encoding/decoding layer are defined in the header file <code>include/nuttx/input/kbd_code.h</code>.
|
||||
These functions provide an matched set of (a) driver encoding interfaces, and (b) application decoding interfaces.
