2.4.12 Set Counter
Syntax :
cmd : 08
value : A 1 byte counter value that can be used with Decrement Counter and
Jump to Address If Counter Not Zero commands to form loops. Practical
values should be between 2 and 255.
Description :
redisplayed over and over to achieve a lengthy viewing. This command when used in
conjunction with
commands allow the user to determine exactly how many times the series of images are
looped.
For example, we may want to animate the Globe rotating. Let’s say we have 10 image
slides of the Globe at different rotated positions residing in the memory card. When the
images are displayed sequentially, the effective duration will only be the length of time it
takes to display the 10 image frames. We can increase that length by looping through
the animation a number of times depending on the value set in the counter. When the
display reaches the end of the last frame and encounters the
followed by
decremented and then the internal pointer will jump to the memory Address specified in
the “Jump to Address If Counter Not Zero” command. This sequence will repeat until the
value in the counter reaches zero. The following demonstrates how this maybe used:
Note :
the memory card and then executed by using the
command. The commands would offcourse be the series of hex codes.
Address (dec)
00000000
00000002
00000012
00000015
00000025
00000119
00000129
00000132
00000134
The above example is typical of how a series of commands might be loaded into
