Simple operator interface

Attached is the beginnings of a (fairly) simple operator interface that uses the Mouse, Keyboard and VGA Objects.·· It is written for the demo board· rev c

· This is my first Propeller project so I've commented it liberally for fools like me still at the beginning of the learning curve.

·The machine will be something like a candle-making system that moves to position and dips several layers then cools the candles before a batch is finished.

·The positions, ·layer count, speeds·and times all need to be input by the operator,· this is the easiest way I could quickly design to do it.


I still need to add keyboard input for batch numbers and notes, but I am having difficulty with the fact that the text.str xy position set function does not let you use a variable.· ·Does anyone have an easy fix for this?

I'll also be doing data logging.

As of now my plan is to just send everything out as RS-232 to a PC doing nothing but data logging. If we had·something like a "Memory Stick" or "jump drive" object, it would make the world a beter place.

I see that ·rokicki ·has a good start, but I don't see that he's done with it yet. Anyone else working on storage that might also be PC readable?


I've been coding for quite a while now and I'm rarely in awe of anyone. Now however I find a bit of "hero worship" creeping in for Chip and the rest of the group that has contributed to the Propeller.·

When I had to learn Windows CE, had I been a nuclear power and had an easy button at the time, Seattle would be the largest hole in the northern hemisphere.· Now, learning the Propeller, ·Spin, and it's tools, I find I am having the exact opposite experience.

Programming is starting to be fun again.

Thanks everybody.

    Ken,

    To pass positioniong variables via the .STR method, just make a short VAR string that has a few bytes in it: the command, the x and/or y, and a 0. Pass the address of the string to the .STR method using the @variable operator. For example:

    VAR

    · byte xystring[noparse][[/noparse]4]

    PRI position(x, y)

    ·· ·xystring[noparse][[/noparse]0] := positioncommand·· 'put the command byte value here

    ·· ·xystring[noparse][[/noparse]1] := x

    ·· ·xystring[noparse][[/noparse]2] := y

    ··· xystring[noparse][[/noparse]3] := 0

    ··· gr.str(@xystring)··· 'call the graphic object's string method to perform the positioning

    Chip:
    LOL... Ok, I haddn't thought of that. I just created a PUB VGA.PSET(X_Cord,Y_Cord),copied the code you wrote into it, ·and called that.

    Ken:· I am workin on one as well, but, in all fairness, the pro's and con's of it all, I think I'm going to junk the project and use the USBWiz for mass storage access.

    I've got the writing pretty much all designed, but real work and other projects have totally
    diverted me away from the Propeller for a bit. I'll get back to it soon, probably next week
    when my wife is in Chicago.
