Multi-Program download

Daniel M.

hey,
i have written multiple programs to preform different functions with a custom robot i built for school. Does anyone know of a way to load all of these programs at once and write another program that will allow me to choose which one to call with the debug terminal or by the setting of switches? Thanks

Put your menu in slot 0, then -- based on you selection (switches, etc.) -- use the RUN instruction to jump to the desired program slot. When that slot finishes it should use RUN 0 to get back to the menu. I've done this with a couple robots and it works well (note you must have at least a BS2e to use RUN).

I have just a BS2, is there another way to do something like that?

Sure, just create a 'main' routine that reads the DIP switches (or whatever) to select your program. Then 'GOTO' the appropriate program.

Note with only 2K Bytes of EEPROM program storage, you'll be fairly limited in how different your programs can be.

Sure, there are a number of mechanism to do what you want.· I'd use something like this:

Main:
  DO
    GOSUB Important_Background_Task
    GOSUB Get_Selection
    ON select GOSUB Task_0, Task_1, Task_2, ...
  LOOP
 
 
Important_Background_Task:
  
  ' do stuff here that has to happen when you return from a task
 
  RETURN
 
 
Get_Selection:
 
  ' read switches, etc., to determine what task to run
 
  RETURN
 
 
Task_0:
 
  ' this will run when select = 0
 
  RETURN
