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 |
