AVR sound can be generated from a simple
design on a development board, to something which gives full digital
sound playback. It is possible to stream MIDI files as playback, all
possible through some simple coding of your AVR chip. Some of the range
of Atmel AVR micro controllers, actually come with sound generating
firmware installed upon them, but the ability and beauty of these micro
controllers, is the fact that you can tweak and recode anything to your
own design. It is possible to create a playback system for an iPod or
any mp3 player, through which the AVR chip can emulate the sound into
full audio waves for the ear to hear. The fun of such projects is in
designing and building such things yourself. It is also possible to add
sound effects and voice samples to your AVR micro controller, to you
give your project a little extra personal touch. You can get full
output sound in stereo, by integrating a headphone output jack into
your circuitry, which will be controlled by the programming done with
the micro controller itself. There are many ways to approach the
development of producing sound and playback of MIDI files through a
controller, and experimenting with AVR sound is a good way to approach
the coding of micro controllers.
The abilities of the micro controller
in a circuit for producing sound output vary from entry level to
advance, so there is plenty of scope for learning.
AVR sound offers plenty of choice to meet your exact needs. By
programming the micro controller through a software interface on your
personal computer, you can access any sound firmware that is already
loaded on it, but you can also compile your own script to run the
specifics of any sound project that you will need. AVR sound is just
one of the many fun components and capabilities of building circuitry
and robotics with AVR micro controllers. The ability to add sound to
your AVR projects opens up doors of possibilities for current and
future projects.
The utilization of AVR micro controllers is relatively simple by
design, and it is what has sparked their popularity. By running all
operations through a personal computer software command center, then
the fine-tuning of AVR sound is simplified. All coding can be done and
compiled within the software, as well as running any debugging systems
which may need to come into effect. By learning how to debug, you will
be better equipped ahead of the next script you write. Learning the
side of building technology and learning the side of coding the
programs to exploit the full potential of your circuits is all the fun
and challenge of the world of AVR.
