2.3 INTERNAL PROGRAM (USER PROGRAMS)
The Internal Program allows you to execute automatically (and without PC connection) a user-
created program which is stored in the display board. Up to 50 programs may be stored (and are
identified by a sequential number).
Let's suppose for example that you want to execute the following:
 Reset the display board.
 Write a string in large font and display it for 20 seconds.
 Show the clock for 10 seconds.
 Write a scrolling string for 1 minute.
 Go back to the beginning and repeat the sequence 10 times.
This program can be created and stored with the Microgate software or with a series of
commands sent one after the other. To store the program, transmit the ‘Start Program’ command,
then the program command sequence, and finally the 'End Program' command. This operation
must be carried out with the display board set to the Base Program.
In addition to the regular commands, an internal program can contain instruction cycles that are
repeated automatically many times or infinitely. The commands to repeat must be preceded by
the ‘Label' instruction which identifies the program point where the commands to be repeated
begin. This command succession must end with the 'Loop-Goto' instruction, which allows you to
indicate the number of times the cycle must be repeated.
