3-18 EPSON UTILITIES (S19A-B-001-03)
4 13504VIRT DISPLAY UTILITY
13504VIRT shows the virtual display capability of the S1D13504. A virtual display is where the
image to be displayed is larger than the physical display device (CRT or LCD) and can be viewed by
panning and scrolling. 13504VIRT allows the display device to be used as a “window” to view the
entire image.
The 13504VIRT display utility must be configured and/or compiled to work with your hardware
platform. Consult documentation for the program 13504CFG.EXE which can be used to configure
13504VIRT.
This software is designed to work in both embedded and personal computer (PC) environments. For
the embedded environment, it is assumed that the system has a means of downloading software from
the PC to the target platform. Typically this is done by serial communications, where the PC uses a
terminal program to send control commands and information to the target processor. Alternatively,
the PC can program an EPROM, which is then placed in the target platform. Some target platforms
can also communicate with the PC via a parallel port connection, or an Ethernet connection.
4.1 S1D13504 Supported Evaluation Platforms
13504VIRT has been tested with the following S1D13504 supported evaluation platforms:
• PC system with an Intel 80x86 processor.
• M68332BCC (Business Card Computer) board, revision B, with a Motorola MC68332 processor.
• M68EC000IDP (Integrated Development Platform) board, revision 3.0, with a Motorola
M68EC000 processor.
• SH3-LCEVB board, revision B, with an Hitachi SH-3 HD6417780 processor.
If the platform you are using is different from the above, please see the “S1D13504 Programming
Notes and Examples,” document number S19A-G-002-xx.
4.2 Installation
PC platform: copy the file 13504VIRT.EXE to a directory that is in the DOS path on your hard
drive.
Embedded platform: download the program 13504VIRT to the system.
4.3 Usage
PC platform: at the prompt, type 13504virt [/a] [/w=???].
Embedded platform: execute 13504virt and at the prompt, type the command line argument.
Where: no argument panning and scrolling is performed manually
/a panning and scrolling is performed automatically
/w=??? for manual mode, specifies the width of the virtual display
which must be a multiple of 8 and less than 1024 (the default
width is 1024 pixels); the maximum height is based on the dis-
play memory and the width of the virtual display
