At this point, the Propeller tool should be installed and ready to go. Let’s test it out.
15.3.1 Launching the Propeller Tool
The Propeller tool communicates to the Propeller chip over a single 2-line serial connection with the standard RS-232
TX/RX pair along with DTR (data terminal ready) as a reset line. The Chameleon’s USB serial port is used for the
communications channel for the Propeller chip. However, if you recall, the USB serial port can be used by the AVR or the
Propeller. The device that gets connected to the port is controlled by the serial selection switch next to the RESET button.
Simply place the switch in the UPPER position to select the Propeller chip to have access to the USB serial port. This is
shown in Figure 15.65 below.

If you have trouble installing the USB drivers, there is another “stand alone” installer that
will do a “force install” on them. The name of the file is:
USBDriverInstallerV2.04.16.exe, it’s located in the directory CHAM_AVR \ TOOLS \
DRIVERS \ and usually will deal with any problems encountered during normal
installation.
