PUG003003-1011 Page 8 of 19 ZAURA™ RF Wireless Modules Product User Guide The ZAURA RF Wireless Modules Development Kits ship with Zilog’s ad-hoc peer-to- peer software loaded into the Z8F2480 microcontroller’s Flash memory. An example proj- ect, also included, allows users to investigate custom options. When combined with the Zilog Developer Studio Integrated Development Environment (ZDS II IDE) and debug tools, available from Zilog, developers can make changes to user source code which is included with the software project. Software Operation Developing with the ZAURA RF Wireless Modules requires a PC running a serial termi- nal program; for purposes of demonstration, HyperTerminal is discussed in this document. To get started, observe the following brief procedure. 1. Install two AA batteries on the reverse side of the development board and slide switch SW3 to the BAT PWR ON position. Alternatively, when used with the USB interface, power can be supplied from the USB port if SW3 is set to the USB PWR ON position. 2. Connect a USB Mini-B to Type A cable between the ZAURA RF Wireless Module and a PC running Microsoft Windows (Zilog recommends Windows 7). The PC will begin to enumerate the USB device and should automatically download the appropriate PC software from the Internet. This software allows the ZAURA RF Wireless Module’s USB interface to be used as a virtual COM (serial) port on the PC. After this software has been installed, note the port number of the new (virtual) COM port that has been added to the system. 3. To send commands to the Module, configure HyperTerminal for 57,600 bits per second, 8 data bits, no parity, 1 stop bit and hardware flow control. It is necessary to configure HyperTerminal to use the virtual COM port added to the system in the previous step. By default, the ZAURA RF Shell Library does not echo typed characters back to the console. To see typed characters, it is therefore necessary to either configure HyperTerminal to enable Local Echo, to issue the uecho on console command, or to rebuild the project with the ZAURA_RF_UartEcho configuration variable set to TRUE in the ..\\Conf\\ZAURA_RF_Conf.c configuration file. 4. Apply power. A user prompt should appear on the terminal. If the prompt does not appear, press the Enter key a few times in HyperTerminal. If the prompt still does not appear, slide SW3 to the opposite position and then back to its original position. When the USB cable is disconnected and reconnected from the ZAURA RF Wire- less Module, it is necessary to restart HyperTerminal so it recognizes that the vir- tual COM port is present. Refer to the ZAURA RF Wireless Module Shell User Manual (UM0235) for command details. Note:
- Connect the development board to a PC using a USB Mini-B to Type A cable.
- Launch HyperTerminal on the PC.
- Configure HyperTerminal for 57,600 bits per second, 8 data bits, no parity, 1 stop bit

AA batteries have been installed. b. Jumpers J3 and J5 are in place.
- The ZAURA RF Wireless Library is co ntained in a zip file labeled PUG0030-
of this zip file to an appropriate location on your hard drive.
- Launch ZDS II, navigate to ..\\ZAURA_RF_Wireless_vX.XXy\\Demo and open the
ZAURA_RF_Demo.zdsproj project file, which is located inside the Demo folder. Table 3. ZAURA RF Wireless Module Library Components ZAURA_RF_866p5_MHz.lib An RF library for the 863 to 870 MHz ISM band. ZAURA_RF_915_MHz.lib An RF library for the 902 to 928 MHz ISM band.
PUG003003-1011 Page 10 of 19 ZAURA™ RF Wireless Modules Product User Guide vX.XXy refers to the version of the ZAURA RF software that was downloaded in Step 1. 3. In the Build Configuration window, select either the 866p5_MHz build option or the 915_MHz build option based on the frequency band of the Module you are using. 4. Next, select the Build → Rebuild All menu option. 5. Download the project using the Tools → Flash Loader option or the Debug → Go menu option. Some functions of the Demo project will place the Z8F2480 MCU into Stop Mode, which will terminate the debug session. Run the Demo without a Terminal When power is initially applied to the ZAURA RF Wireless Module and its development board, LED D1 and LED D2 will each illuminate. After initialization completes, LED D1 is extinguished and LED D2 remains illuminated. Red LED D2 illuminates to indicate that the ZAURA_RF_Demo firmware is running and the radio is in Receive Mode. When SW1 is pressed, the state of LED D1 on the (local) ZAURA RF Wireless Development Board is toggled and a broadcast message is transmit- ted to other ZAURA RF Wireless modules. Modules within radio range of the transmitter that receive the broadcast will configure LED D1 on their development boards to match the state of LED D1 on the transmitter. Nodes that do not receive the broadcast will not change the state of LED D1 on their development boards. For example, if LED D1 is ini- tially OFF and SW1 is pressed, LED D1 is illuminated on that node and a broadcast mes- sage is transmitted, directing other ZAURA RF modules to illuminate LED D1 on their development boards. Any modules that do not receive the broadcast will not alter the state of LED D1 on their development boards. If SW2 is pressed, both red LEDs D1 and D2 turn OFF, indicating that the ZAURA RF Wireless Module is in a low power state and is unable to communicate with other nodes. If SW1 is pressed while the Module is in the low power state, the unit is returned to Active Mode, LED D2 illuminates, and the radio is placed into Receive Mode. Run the Demo with a Terminal When the ZAURA RF Wireless Module is used with a USB Mini-B to Type A cable con- nected to a PC running HyperTerminal, the operator can use the interactive console to send and receive arbitrary packets in response to commands entered on the console. For example, in the console display that follows, the operator sends the message, "Hello world" to a specific Module, changes the Module’s station address and manipulates a GPIO port pin on the remote station.
