15.2.3.1 Installing a Serial Terminal Program
The Chameleon AVR has a USB serial port that is used to communicate with the Arduino tool as well as the Propeller
tool. Both of these programs have built in serial communications, but if you just want to send out serial data to and from
the Chameleon you are going to need a good terminal program, we suggest PuTTY.
The PC can talk to either the Propeller chip onboard the Chameleon via the USB port OR the standard serial port on the
AVR chip, this is accomplished via a mechanical switch at the bottom of the board shown in Figure 15.49 below.
At this point, go ahead and make sure the serial select switch is in the DOWN position, so the PC can talk to the AVR thru
the USB serial port.
There are many serial terminal programs available (Hyperterminal for example), but we want you to use one that is very
SIMPLE to setup and that works well with the Chameleon AVR, we are going to use “PuTTY”. From the DVD-ROM, install
this program:
It is called “PuTTY” and is very easy to use. Once installed, it will create a shortcut on your desktop. Click the shortcut to
run the program, you will see a dialog like that shown in Figure 15.50.

chip. In the DOWN position it selects communication with the AVR chip.
