You already installed the Propeller tool, so all we have to do now is run the tool which is very simple. The first step is to
make sure that the PC recognizes the Chameleon and installs a virtual USB COM port. When you connected your test
Chameleon AVR to the PC via the USB cable and powered the Chameleon up, the FTDI drivers on the PC should have
detected a NEW USB port and assigned a COM port to it, you can find the COM port # in the system devices menu. You
will need this later for the serial communications test, however, the Propeller took will autoscan all COM ports until it finds
the Propeller chip connected to one. With that in mind, here are the steps to load the firmware into the Propeller chip, you
will do this for every Chameleon AVR (and PIC) in the final testing process.
Step 1: Launch the Propeller IDE tool by clicking the shortcut on the desktop.
Step 2: Navigate to where you copied the source directory files on your PC and open the master file
cham_default2_drv_112.spin (latest copy). It is located on the DVD-ROM here:
DVD-ROM :\ CHAM_AVR \ SOURCE \ PROPELLER_DRIVER \
This is shown in Figure 15.66 (ignore my slightly different hard drive paths).
Figure 15.66 – Loading the Propeller firmware into the tool.
Once the source code is loaded into the tool, you simple have to download it into the Chameleon AVR. Make sure that
you have the USB cable plugged into the Chameleon, power is ON, and the serial selection switch is in the UP position.
When you are ready then you can press <F11> on the Propeller Tool, or from the main menu, you can select <RUN-
>Compile Current ->Load EEPROM> the results will be the same, the Propeller tool will scan all COM ports for a
connection to a Propeller chip, and then compile and download the firmware to the Chameleon. This is shown in Figure
15.67.
