Script

---

These methods allow developers to control DUE Scripts right from within Python, JavaScript or .NET

• Script.New() - Clears the program stored in flash
  
• Script.Load(script) - Loads the line into internal buffer
  script: Line to load into internal buffer
  
• Script.Record() - Sends the internal buffer to the device, overwriting any previous programs
  
• Script.Read() - Read the program stored in flash and return as string
  
• Script.Execute(script) - Executes the single line of code immediately
  script: Script to be executed
  

This is an example to execute a single line in immediate mode. This does not modify the application stored in flash.

• Python
• JavaScript
• .NET

duelink.Script.Execute("LED(200,200,10)")

This example will check any script stored in flash, and clear them if program found.

• Python
• JavaScript
• .NET

currentScript = duelink.Script.Read()

if (currentScript != ""):
    duelink.Script.New()

This example will load a simple program line by line and then record it. Variable c is used to indicate how many times the LED will blink for, which is 10 in this case.

• Python
• JavaScript
• .NET

duelink.Script.Load("c = 10")
duelink.Script.Load("@Blink")
duelink.Script.Load("Led(100,100,c)")
duelink.Script.Record()

You can then access a previously recorder program using goto (to label) or by calling a function that has a return. This example calls the recorded program above by executing a single line that contains two commands. The first one sets c to 5 and the second will send execution to @Blink, which will cause the LED to blink 5 times.

• Python
• JavaScript
• .NET

duelink.Script.Execute("c=5:goto Blink")
