the programming process again. This section describes a different method for programming that will allow you to
compile and program simply by pressing F5.

First, in the View menu, select “Available Atmel Tools”. This will bring up the “Available Tools” window. Make sure
that there is one and only one STK500 in the list and make sure that the COM port number matches the COM port
number of the Pololu USB AVR Programmer Programming Port, which is displayed in the Device Manager. If there
are multiple STK500 entries, right click on them and select “Remove” to remove the extra entries. You will only have
to do this once.

Next, open the project properties window by opening the Project menu and selecting “Properties…”. In the Tool tab,
select STK500 as the debugger/programmer, and select ISP as the interface. You will only have to do this once per
project. You can also set the ISP Clock speed here but please note that the frequencies displayed in Atmel Studio are

not correct

when you are using the Pololu USB AVR programmer (see

Section 3.e

for the correspondence). It is a

good idea to set the frequency to something between 80 and 90 kHz (which will result in 200 kHz on the Pololu AVR
Programmer) at first and to try increasing it later once F5 programming is working.
