Can PropBasic call .spin files as Tasks

Regor · 2010-03-12 22:50

I download PropBasic and its ultra cool.

I noticed when I wrote a task a .spin file actually got generated which got me thinking.

Is there a way to include Spin files not generated from the PropBasic Tasks? Aka, can I move·AnyonesCool.Spin file into the PropBasic folder and then use it within my PropBasic program?

You'd need to get this confirmed by Bean, but I don't think it's that simple. Take a look inside those .spin files and you'll actually see a load of PASM.

That said; Bean has given an example of calling other code - look for his "dispatcher". <edit> See http://forums.parallax.com/showthread.php?p=867134 - third post from bottom.</edit>

The "Dispatch" demo is what to use. I don't know if it will use an object called from another object yet. I was going to try that this weekend.

Here is a demo program showing how to interface spin objects into PropBASIC using a spin dispatcher.


If you try this demo, make sure it's NOT in the same directory as the keyboard demo PropBASIC code. The PropBASIC keyboard demo creates a "keyboard.spin" file that is NOT the one we want to this demo.


You can see that I used an ASM...ENDASM block to insert the object and dispatcher code. Even though it's not PASM code, the ASM...ENDASM commands don't care they just put whatever is between them into the output file.
' Put in code to run spin dispatcher
ASM
OBJ
  Key: "Keyboard"
 
PUB SpinStart
  CogInit(1, @__Init, @__DATASTART) ' Start PropBASIC program
  Repeat
    case spinCmd
      spinKeyStart:
        Key.Start(spinP1, spinP2)
        spinCmd := 0
               
      spinKeyGetKey:
        spinP1 := Key.GetKey
        spinCmd := 0
 
ENDASM
 
If you have any questions about how this works, please let me know.

Yeah the "dispatcher" is a method I came up with to call spin objects.

It may not be the ONLY way, but it is probably the easiest way.

Basically, you keep the spin program alive and wait for requests from PropBASIC. All data exchange is handled with HUB variables in PropBASIC.
PASM code in .spin files can be pretty easily inserted into PropBASIC, but "spin" code cannot and must be called using the dispatch method.

Bean,

So, what you are saying I can't call a method I did in spin like this "method.spin".

Bean,

So, what you are saying I can't call a method I did in spin like this "method.spin" as a TASK.
