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programs, superseded old methods of using memory which could only be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.
