An AVR keyboard encoder can
be designed and coded with the help of AVR Studio and any one of the
ranges of chips on offer from Atmel. A keyboard encoder will allow you
to emulate a keyboard operation through an external controller such as
a joystick or a trackball. This is a great idea to work on either a
simple project from home to develop your compiling and circuitry
skills, with parts taken from old keyboards and an AVR from off the
Internet. With the AVR's expansive functionality, there is plenty of
scope to refine the operation of the encoder to meet your exact needs.
An AVR keyboard encoder will convert any commands that are inputted
from a switch, keypad or any other input device, and will treat them as
signals coming from a regular keyboard. So instead of pressing keys to
type, you will be able to press a button instead to get the desired
keyboard command on your PC. This is something that can completely
replace the need for a computer keyboard upon start-up, because the
emulators will still be read as a keyboard being present. The main
benefits of this, is that you can finely tune a keyboard emulator to
work efficiently with your own program set. Programs do not require a
full range of
keyboard strokes to operate, so you can specify the
commands that are used most frequently into an encoder in order to save
you time. As many computer applications actually do require some input
from the keyboard, it is not necessary to have one with an AVR keyboard
encoder. There are numerous reasons why one would want to use an
emulator over a keyboard, environmental circumstances for instances,
could be easier with a simple keyboard as opposed to trying to handle a
full keyboard. By streamlining the most important commands into a
keypad or other input device, it can speed up the operation of computer
input. Such is the ease of customizing AVR micro controllers; there is
a whole world of opportunity at your fingertips.
With some language scripting knowledge, or, even if you do not know
anything about it, there are plenty of help guides and tutorials
available freely to get you started, you can begin to program and
explore the world of AVR. Projects such as making an AVR keyboard
encoder is
something that is rewarding and will allow you to understand the full
potential of the chips flash, EEPROM (Electrically Erasable
Programmable Read Only Memory) and SRAM (Static Random Memory). The
power of the AVR lies in its ease of use and the efficiency that it
delivers.
