The eZ80® Sales Demonstration Platform can be powered by the on-board batter- ies (stand-alone configuration) or by the AC adapter. Both configurations feature: • Serial communication using eZ80® UART ports and adapter board connectors • Ethernet communication using the eZ80L92 or eZ80F92 module • LCD displays relevant demo data • ZDI operation using external ZPAK Caution: Do not use battery power and AC power at the same time. Doing so will damage the board. eZ80® Sales Demonstration Platform Block Diagram Figure 2 illustrates a block diagram of the eZ80® Sales Demonstration Platform.

Overview A single software project called ez80l92_demo_platform.pro is included on the eZ80® Sales Demonstration Platform CD-ROM. The demo software is preloaded into eZ80L92 Flash memory. Connect the demonstration platform to a PC as described below and the demo is ready to run. Instructions for loading the demo project are also included for code download and debugging demonstrations.
PCB Notes • To use batteries in this demonstration, load four 1.5-Volt batteries into the bat- tery holder and turn on battery switch S1. • X10 port J10 is not loaded for this release. • The LCD module is a Matrix Orbital LCD2041. For further information about the Matrix Orbital LCD2041 20-column by 4-line display, go to www.matrixor- bital.com. This LCD display is a 5-volt display with an I2C or RS-232 interface. This kit uses the I2C interface only.
Demonstration Setup Procedure Ensure that the eZ80® Sales Demonstration Platform is configured and working properly as described in the eZ80® Sales Demonstration Platform Quick Start Guide (QS0024). Then disconnect the ZPAKII from the PC and platform and per- form the following procedures. Use Figure 4 as a reference. To open COM port

1. Connect a 9-pin serial cable from the PC COM port to connector COM1 on the eZ80® Sales Demonstration Platform. 2. On the demonstration platform, do one of the following: Connect power to the platform using the AC adapter. or Insert four AA batteries into the batter holder on the bottom of the demonstration platform and turn the BATTERY switch on. The two LEDs on the demonstration platform blink alternately and the LCD scrolls feature information for the eZ80L92 chip and eZ80L92 module twice. When the display completes, the LCD screen displays the time and date. Proceed with the following instructions to establish communication between the PC and demonstration platform. Caution: Do not use battery power and AC power at the same time. Doing so will damage the board.
3. Launch HyperTerminal on the PC by opening the Start menu and selecting Programs → Accessories → HyperTerminal, or Programs → Accessories → Communications → HyperTerminal, depending on your Windows OS version. 4. In the Connect To dialog, set the Connect Using: drop-down menu to match the COM port to which the eZ80® Sales Demonstration Platform is connected. Click OK. 5. In the resulting COMx Properties dialog, enter the following port settings and click OK: Bits per second: 57600 Data bits: 8 Parity: None Stop bits: 1 Flow control: None 6. Press the RESET button (SW1) on the eZ80® Sales Demonstration Platform. The demonstration platform scrolls through the eZ80L92 and eZ80L92 module features twice, then displays the time and date. When the demo completes, HyperTerminal displays the following: ZiLOG eZ80 Demonstration Platform Program (1.0) Featuring the eZ80L92 eZ80L92>

Deactivating the Real Clock Time Clock removes the date and time display from the demon- stration platform LCD screen. Set Date Sets Real Time Clock date. backlight - On/Off Toggles the demonstration platform LCD screen on and off. Display Memory Displays the contents of a specified memory segment. Allows the user the specify a starting address and number of bytes to display. Set Time Sets Real Time Clock time. Write to LCD Allows the user to write up to four lines of 20 characters each to the sales demonstration platform LCD display. Decrease LED blink speed Slows the blink rate of the two LEDs on the demonstration plat- form by 16ms each time the user presses the 2 or - key. Press- ing switch SW2 on the demonstration platform has the same effect. Increase LED blink speed Increases the blink rate of the two LEDs on the demonstration platform by 16ms each time the user presses the 3 or + key. Pressing switch SW3 on the demonstration platform has the same effect.
