13505SHOW Examples
The 13505SHOW demonstration program is designed to both demonstrate and test some of the
features of the S1D13505. Some examples follow showing how to use the program in both instances.
Using 13505SHOW For Demonstration
1. To show color patterns which must be manually stepped through all bit-per-pixel modes, type
the following:
13505SHOW
The program will display 16 bit-per-pixel mode. Press any key to go to the next screen. The
program will display 15 bit-per-pixel mode. Once all screens are shown the program exits. To
exit the program immediately press ESC.
2. To show color patterns which automatically step through all bit-per-pixel modes, type the
following:
13505SHOW /a
The program will display 16 bit-per-pixel mode. Each screen is shown for approximately 1
second, then the next screen is automatically shown. The program exits after the last screen is
shown. To exit the program immediately press CTRL+BREAK.
