I like that idea of debug programs and joystick calibration programs. Last year our robot had a feauture where if you moved the thumb wheel on joystick 1 the joysticks would be auto-calibrated. It was a great feature but took away from loop time so it was abandoned.
You can switch from program to program by using the command 'run x'. Where x is the program number, 0-7 with 0 being the default on power-up. You can share variables globally, however they still must be initialised in each program. A word of caution to FIRST programmers: if you do not initialise variables in the same order as they were the first time they were initialised you will have many problems sharing correct variables.

: Another cool thing you could do is to have a 'set up/debug' program that would zero joysticks exercise particular PWM's etc. I suppose that the programs all have access to the same eeprom space so values could be passed from one program to another.

: This would allow for killer loop times as you say, while having all the other stuff available if you need it.

: How do you switch from task to task by the way?

: Can the programs choose to switch between themselves? If so (and again, assuming eeprom space is common) then perhaps we could even set up a kind of subroutine structure.
