Ashley,

That is exactly the intent, A visual programming language where the user
simply drops objects,
Then selects events and properties.

ie. Drop Timer. Set Period property to 1 sec, set event to READ ADC
    Drop ADC, Set ADC high threshold property = say 2V, set event = Send Com
Message
    Drop Comm Message. Set message type = ADV Over voltage

Regards

David Huisman

Hi David,

I've been thinking of implementing a state machine/compiler for the PIC for
a little while and it strikes me that for simple tasks like that it might be
easier for a novice to understand a graphical drawing of a state
machine/flow chart type of display..

Have you considered making the language more like a state machine? To be
effective for a novice it would need to be graphical though I would think..

You could then have segments of code executed on transitions, and conditions
are constantly checked on the current state. Again these would be arbitrary
conditions (ADC > 20, PortB.1 = 1, Serial Data Arrived, etc)

Cheers,
Ash.
