3.9.28 Path
[Path]
section lists the execution flows in the
Q-Code
program sheet, each execution flow is named as
a “PATH”. There are 2 kinds of path, one is the Foreground Path to play voice or melody mostly, and
the other is the Background Path to cooperate with the Foreground Path for background output.
Each Foreground Path consists of the path name and Steps. The path name is a symbol which leads a
line prior to a colon “:”. The paths can be linked to some trigger event of input-pins by
[Input State]
and
[Output State]
sections or direct called by another path.
Note: While system executing each in Path section, if there are no PlayV, PlayS, Delay, Stop and
StopV command to stop current playing, after executing other commands, program will
go back to play or delay command address to execute next command. In Q-Code system,
it’s not necessary to add extra path for return to next command.

[Input State]
KEY1: TR1R

[Path]
PowerOn:
KEY1
TR1R: PlayV(Ch1, $V0), Delay(1)

TR2R: R0=5
; Execute R0=5. If system is executing PlayV or Delay command, it will return after R0=5 is
