TTL Serial Port
This section is used to identify pins A and B with serial handshaking lines so that they can
be used as general purpose user I/O lines. See
.
AVR ISP Emulation
This section is used to change the hardware and software version numbers of the
programmer. These numbers are read by AVR Studio when it connects to the programmer
and are expressed in
hex
. If these numbers do not match the numbers that AVR Studio
expects, then it brings up a dialog asking if you want to upgrade (or downgrade) your
programmer’s firmware; the Pololu AVR USB programmer does not support this method
of firmware upgrading, so this dialog is nothing more than a nuisance to those not using
an Atmel programmer. You should click Cancel to ignore the message and proceed to the
AVRISP programming dialog. To prevent this firmware-upgrade dialog from appearing in the
future, set the numbers here to the numbers that AVR Studio says it expects.
