3. With the USB A (male) to Mini-B cable, connect Port P3 on the eZ80Acclaim Plus!
Development Board to a USB port on the development PC to apply power to the
Development Board, as highlighted in Figure 5.
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 eZ80Acclaim
Plus! 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 11). Before running the starter program, how-
ever, the eZ80Acclaim Plus! 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.
