5. To show the color patterns in SwivelView™ 90° mode, type the following:
13506SHOW /r90
The program will display the default color depth (as selected in 13506CFG). Press any
key to go to the next screen. Since SwivelView™ 90° is limited to color depths of 8,
15 and 16 bpp the program exits. To exit the program immediately press the Esc key.
The “/r90”, “/r180”, and “/r270” switches can be used in combination with other com-
mand line switches.
6. To show solid vertical stripes, type the following:
13506SHOW /s
The program will display the default color depth (as selected in 13506CFG). Press any
key to go to the next screen. Once all screens are shown the program exits. To exit the
program immediately press the Esc key.
The “/s” switch can be used in combination with other command line switches.
Using 13506SHOW For Testing
1. To show a test grid over the 8 bpp color pattern on an LCD, type the following:
13506SHOW bl=8 /g
The program will display the 8 bpp color pattern overlaid with a white grid 20 pixels
wide and then exit. The grid makes it obvious if the image is shifted or if pixels are
missing. Note the grid is not aligned with the color pattern, therefore the color
boxes will not match the grid boxes.
The “/g” switch can be used in combination with other command line switches.
2. To test background memory reads to the CRT, type the following:
13506SHOW bc=16 /read
The program will test screen reads. If there is a problem with memory access, the
displayed pattern will appear different than when the “/read” switch is not used. If
there is a problem, check the configuration parameters of 13506SHOW using the util-
ity 13506CFG. See the 13506CFG user guide, document number X25B-B-001-xx, for
more information.
The “/read” switch should be used in combination with the “b=” setting, otherwise the
test will always start with the default color depth (as selected in 13506CFG). To exit
the program after using “/read”, press the Esc key and wait for a couple of seconds
(the keystroke is checked after reading a full screen).
