Please refer to the aforementioned referenced User Guide in Section 1.2 for complete installation instructions. 3.3 Connecting the CEL ZICM35x Module to the PC After finishing the installation of the CEL MeshConnect ZICM35x Test Tool and loading any necessary drivers, connect the CEL ZICM35x module to a PC via a USB port. 4. The CEL MeshConnect ZICM35x Program The CEL ZICM35x Test Tool starts with the Top-Level Window, which supports the connection of the CEL ZICM35x module to the PC via serial port. Next is the Operation Mode Selection Window, as the Test Tool supports two types of testing: Hardware Evaluation and ZigBee Network. The program then proceeds to the Main Window where user-interactions occur. 4.1 Top-Level Window The Top-Level Window allows the user to manually specify the connection parameters or lets the application automatically choose the suitable target. This application supports CEL ZICM35x modules only and it will not return a response if another device is connected. The user can also use Flash programming to download a new firmware image to the internal Flash of the target (see Section 6.2). Features: Connect to the specified target via the Communications Settings or Auto Detect options. Download a new firmware image to the target via the Flash Programming Window. 4.2 Auto Detect The MeshConnect Test Tool can automatically connect to a target which is connected to the PC, as shown in Figure 6. It starts from the first COM Port and stops when it reaches the first valid target or the last COM Port. Within each COM Port, the application detects the baud rate from 7,200 ~ 128,000 baud. While running auto detect, the Figure 6 CEL MeshConnect ZICM35x Test Tool User Guide 6

7 progress bar will be displayed to show the status of detection. If the application detection is successful, the program will show the Mode Selection window. Otherwise, the application detection has failed and an error message will appear. The user must wait five seconds after powering up or resetting before attempting to communicate with the MeshConnect Test Tool. 4.3 Communication Settings Window If auto detection of the COM port is not desired, the COM port can Figure 7 be manually selected. First, select Communication Settings in the menu bar. After selecting Communication Settings in the Top-Level Window the Communication Window shown in Figure 7 is displayed. In this window, use the COM port identified in Section 6.1 and baud rate to connect to the target. The default baud rate is bps. 4.4 Operation Mode Selection Window After successful target detection, the user can select one of two operation modes as shown in Figure 8: ZigBee Mode or Hardware Evaluation Mode. ZigBee Mode In this mode, a ZigBee network with two nodes is formed to test the RF performance of the modules. Modules can either be configured as the Coordinator of the ZigBee network (shown by the illumination of LED0), or the End Node (shown by the illumination of LED1). For more details on ZigBee Mode, please see Section 4.5. Figure 8 Hardware Evaluation Mode This mode is used to evaluate the features of the module, such as: RF performance, Packet Error Rate Test (PER), Range, ADC, etc. LED3 is illuminated on the evaluation board to indicate the successful entry into this operation mode. For more details on Hardware Evaluation Mode, please see Section ZigBee Configuration Window If the user selects ZigBee Mode as the Operation Mode in Figure 8, the user can form a ZigBee network by choosing the Coordinator option, or join an available network by choosing the End Node option. CEL MeshConnect ZICM35x Test Tool User Guide 7

Figure 51 Get Voltage button: The Get Voltage button returns the voltage present at the PB5 ADC input on the Universal Evaluation Board.On the Silicon Labs Evaluation Board it returns the value from the output of the temperature sensor. Get Temperature button: Will retrieve and display the temperature in Celsius ( C) in the respective box of the GUI. CEL MeshConnect ZICM35x Test Tool User Guide 38

39 5.2.7 External Flash Tab The flash memory is included for non-volatile data storage (see Figure 52). Figure 52 Hex Address: the start offset address of the external flash memory, which allows the write/read operation. This value is in hexidecimal, range from 0 to 0xFFFFFF. (Note: Max address the user should set is 0x200000). Length (in decimal): the number of bytes that the user wants to read or write from/to the external flash memory. (Note: the Min value of the length field is 1, the max value is 256). Hex Data to Fill (in hexidecimal): The value that the user wants to program starts from the address which the user specified in the hex address field. This field is represented in 1 byte each. o If the length is larger than 1, for example: length=10. o Hex data = 0A. o Then 10 bytes 0A will be written to the external flash memory from the start valid hex address. Read External Flash: This button allows the user to read the data from the start address. The length of the External Flash is filled in the GUI. The payload (read bytes) are shown in the hyperterminal (see Figure 19). Write External Flash: This button allows the user to write the hex data with the information specified in the following fields: hex address, length and hex data. If the hex address is larger than 0x or the sum of hex address (in hex) + the length (in hex) > 0x200000, the write operation should not be successful. Read ID: The Read ID button allows the user to read the device identification data: o Manufacture identification (one bytes). o Device identification (2 bytes). o A Unique ID code (UID) (1 bytes). Erase: The page program instruction allows bits to be reset from 1 to 0. Before this can be applied, the bytes of memory need to have been erased to all 1s (FF h). o Chip Erase: This function will erase all data on the chip (all values are reset to 1s). o Sector Erase: With this option, the user can choose the sector number to erase. There are 15 sectors to choose. CEL MeshConnect ZICM35x Test Tool User Guide 39

40 Power: o Up: At power-up, the device is in the Standby mode (not the Deep Sleep mode). The device is active and will return to normal state. o Down: This function puts the device in the lowest consumption mode (the Deep Sleep mode). In this mode, the device ignores all Write, Program and Erase instructions. NOTE: The Ext Flash tab will be disabled if the target board does not support non-volatile memory flashing Board Diag. Tab This tab tests the LEDs on the evaluation board (see Figure 53). Figure 53 LED control: The user can set ON/OFF to any LED by selecting the LEDx from drop-down box, choosing ON or OFF and clicking Set LED. The corresponding LED will turn ON/OFF. Evaluation Board Button Test: Click Start and then press SW0 ~ SW3 buttons on the board. The corresponding button will display a Status textbox. Buzzer Test: Click Test Buzzer. The user will hear an audible tone. CEL MeshConnect ZICM35x Test Tool User Guide 40

41 6. Advanced Features 6.1 Manually Identifying the COM Port (UEVB Only) It is necessary to determine the COM port number assigned to the evaluation board so one can communicate with the module. Using Windows Device Manager on the PC, check that the hardware and associated drivers have been properly installed (see Figure 54). Under the Ports (COM & LPT) heading a Silicon Labs (CP210x USB to UART Bridge (COMx) entry will be listed. Take note of the COM port that has been assigned, as it may be needed later.
