The eZ80AcclaimPlus! Development Kit UM024402-0812

eZ80AcclaimPlus! Development Kit

User Manual

To use the USB port as a power source, adjust the shunt on J12 to the 1–2 position.

Running the Sample Starter Project

A sample starter program provided on the ZDS II CD-ROM demonstrates how to write

proper code for the eZ80AcclaimPlus! Development Board. The starter program is written

so that it will default to the UART-to-USB Port P3 on the Board. The program writes a few

character strings either to this port, or to the simulated UART output window when run-

ning the Simulator Debug Tool (see the Viewing the Starter Project Output via the ZDS II

Instruction Set Simulator section on page 12). Before running the starter program, how-

ever, the eZ80AcclaimPlus! Development Board must be connected to your PC.

After you create your own application program, you can use ZDS II to download the code

you created into eZ80F91 memory for testing and debugging.

Procedure

Observe the following steps to build and run the sample starter program for viewing in a

terminal emulation program on your PC, such as HyperTerminal.

While HyperTerminal is discussed in this document, it is not available on Windows 7 or

Vista machines. As an alternative, consider using Tera Term, which is available for down-

load from the Internet.

1. If you haven’t already connected the UART-to-USB cable to the Board, return to the

Connecting the eZ80AcclaimPlus! Development Board to your PC

section on page 8.

2. Launch HyperTerminal. From the File menu, click New Connection.

3. In the

Name field, enter a name that describes the connection.

4. In the

Icon box, select an appropriate icon for your connection, then click OK.

5. In the

Connect To dialog box, and from the Connect using: drop-down menu,

choose the COM port that is connected to the UART-to-USB port on the

eZ80AcclaimPlus! Development Board.

6. In the

Port Settings dialog box, set the following options:

– Bits per second: 57600

– Data bits: 8

– Parity: None

Note:
