AVRDUDE supports two basic programmer types: Atmel's STK500 and the PPI
|
||||
(parallel port interface). PPI represents a class of simple programmers
|
||||
where the programming lines are directly connected to the PC parallel
|

AVRDUDE supports three basic programmer types: Atmel's STK500, appnote
|
||||
avr910 and the PPI (parallel port interface). PPI represents a class
|
||||
of simple programmers where the programming lines are directly
|
||||
connected to the PC parallel port. Several pin configurations exist
|
||||
for several variations of the PPI programmers, and AVRDUDE can be be
|
||||
configured to work with them by either specifying the appropriate
|
||||
programmer on the command line or by creating a new entry in its
|
||||
configuration file. All that's usually required for a new entry is to
|
||||
tell AVRDUDE which pins to use for each programming function.
|
||||
|
||||
The STK500 and avr910 use the serial port to communicate with the PC
|
||||
and contains on-board logic to control the programming of the target
|
||||
device. Several pin configurations exist for several variations of the
|
||||
PPI programmers, and AVRDUDE can be be configured to work with them by
|
||||
either specifying the appropriate programmer on the command line or by
|

programming function.
|
||||
device. The fundamental difference between the two types lies in the
|
||||
protocol used to control the programmer. The av910 protocol is very
|
||||
simplistic and can easily be used as the basis for a simple, home made
|
||||
programer since the firmware is available online. On the other hand,
|
||||
the STK500 protocol is more robust and complicated and the firmware is
|
||||
not openly available.
