Fortunately, for any AVR
troubleshooting that may need doing, there is plenty of help at hand.
Thanks to the design of the chip, and being able to interface with it
through and In System Programming connection, which means that the
micro controller does not have to be removed from any circuitry, the
ability to go back into the chip itself and fix any code that may need
debugging is a relatively simple task. Reliability, flexibility and
efficiency are the keywords behind the philosophy of the Atmel AVR
micro controllers. They offer a very user-friendly work environment,
and through your personal computer, you can tweak the systems to
perfection with the right knowledge of coding.
AVR troubleshooting starts with connecting with the AVR micro
controller. By hooking up to it through a simple serial connection, you
will be able to access the heart of the chip and gain access to its
firmware, programs and variety of memory. AVR micro controllers are
able to use flash, EEPROM (Electrically Erasable Programmable Read Only
Memory) and SRAM (Static Random Access Memory) for speed and
durability. When something goes wrong with your AVR project, or
something is just not quite performing how it should be, the first
place to start is looking at the code. Invariably you will have coded a
lot of the instructions
yourself, because that is what the AVR chips
bring to the table: Customization and compatibility. The chips can be
used for a simple array of tasks, from running a clock to driving a
remote controlled car.
AVR troubleshooting can also be solved by the great community that is
available on the Internet. With forums, schematics and project designs
in abundance from equally keen AVR enthusiasts, you should never be far
from someone being able to help you out. The world of AVR can be both
fun and challenging, and by integrating yourself into communities, and
sharing your experiences, you should in time be able to give something
back to other newcomers once you have honed your skills. AVR
troubleshooting can be a system of the process of elimination and well
thought out debugging patterns. By looking at your compiled code and
seeing how the AVR chip responds, you should have an idea of where to
start to fix things.
AVR troubleshooting can be a great learning experience. By seeing where
things have gone wrong, can either prevent them from happening in the
future, by giving you an extra level of knowledge from having learnt
from mistakes. The experience built from coding may be a slow one, but
it is one that will be untold rewards and personal satisfaction when
you see your AVR system in full flow.
