AVR flash control is part of the
pioneering technology behind the popularity of the Atmel
microprocessors. The processors started making a breakthrough on the
scene in the late nineteen nineties when they new flash architecture
was fully launched. The advent of using flash memory to store and run
programs, superseded old methods of using memory which could only be
written to just once, such as ROM (Read Only Memory) and EEPROM
(Electrically Erasable Programmable Read Only Memory). This newer
non-volatile method of operation, allowed for programs to be stored on
the microcontroller and eliminate any need for any external memory in
order to power it.
AVR flash control can be performed by hooking the microprocessor up to
a personal computer. This is usually done via a serial connection, and
the microprocessor can be accessed while it is integrated into any
circuitry. By using an ISP (In System Programming) interface, the
microprocessor can be accessed while it is currently running. The
benefits of this are that debugging operations can be watched and ran
while the circuitry is in full flow. You will be able to see live
results by watching and analyzing information on screen, with regards
to the AVR. The most popular software is the AVR Studio, which will
provide a whole host of scripting, compiling and debugging tools.
Flash memory
is fast and very reliable and has taken over from older
methods of storage in many aspects of technology and the world of
computers. Because it is powerful and compact, by placing it at the
heart of an AVR microprocessor, it provides the power to host and run
code quickly and efficiently. The microprocessor itself is based on an
old Harvard 8bit RISC (reduced instruction set computer) chip, which
itself simplified a lot of processing power by utilizing a language
which was stripped back to the basics. This, combined with the upgrade
in memory, AVR flash control allowed for great advances in the world of
microcontrollers and is very popular across the world today.
Today AVR flash control is a key element of any good AVR project. The
knowledge to get the full potential from the chip is important, so that
you can expand and make the technology work for you. From the humble
beginnings of being developed by two students in Norway, and then taken
up by Atmel, AVR and flash are synonymous with robotics and circuit
building for any number of purposes and projects, from GPS, to motor
control, to a simple clock. AVR, with its fast clock speeds is fully
customizable through computer coding languages.
