Make the pin definitions configurable based on entries in a config
file. This makes supporting other programmers much easier. Rename AVRprog.pdf to avrprog.pdf. git-svn-id: svn://svn.savannah.nongnu.org/avrdude/trunk/avrdude@67 81a1dc3b-b13d-400b-aceb-764788c761c2

Use the pin configuration specified by the argument. Pin

configurations are read from the config file (see the

option). New pin configurations can be easily added or modified

.It Fl C Ar Config-File
|
||||
Use the specified config file to locate the desired pin configuration.
|
||||
Pin configurations are specified in the config file using a colon
|
||||
seperated field format. The configuration name is the first field,
|
||||
the remaining fields are of the form:

.Ar PIN
|
||||
can be
|
||||
.Ar VCC , RESET , SCK , MOSI , MISO , BUFF , PGMLED , RDYLED , VFYLED , ERRLED .
|
||||
The value is the pin number of the PC parallel port assigned to that
|
||||
function. The
|
||||
.Ar VCC
|
||||
pin can take multible values seperated by a comma. It's value(s) must

come from pins 2 through 9. The default configuration file is
