13505SPLT Display Utility S1D13505
Issue Date: 01/02/02 X23A-B-003-03
13505SPLT
13505SPLT demonstrates S1D13505 split screen capability by showing two different areas of
display memory on the screen simultaneously. Screen 1 shows horizontal bars and Screen 2 shows
vertical bars.
Screen 1 memory is located at the start of the display buffer. Screen 2 memory is located immedi-
ately after Screen 1 in the display buffer. On user input, or elapsed time, the line compare register
value is changed to adjust the amount of area displayed on either screen. The result is a movement
up or down of screen 2 on the display.
The 13505SPLT display utility must be configured and/or compiled to work with your hardware
platform. The program 13505CFG.EXE can be used to configure 13505SPLT. Consult the
13505CFG users guide, document number X23A-B-001-xx, for more information on configuring
S1D13505 utilities.
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. 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.
