Hullo,
Am continuing to fiddle around with Basic.hex this evening (though I must iron a shirt and hit the sack soon...).
Question
is it possible, when using the SERVO command (SERVO <ID> = <POSN>) to use a variable for <ID>? Whenever I attempt this, Servo 0 moves, rather than the expected servo.
e.g. something random (and valueless...) like:
10 Let A = $rnd % 16
20 servo A=$rnd%200
will always wiggle that same leg.
I'm guessing Servo expects a constant, and the interpreter is doing its best for me and getting a 0 for A, unless i'm supposed to use a special character to dereference the value for this instruction?
Anyway, probably time to shut Huno off for the night!
Cheers,
G.

Sorry. the servo id is a constant at the moment. The idea being its safer if you know which servo you are modifying. Incidentally randomly setting a servo to a random value in a loop would cause your robot to go into a 'fit'. I'd be concerned it might damage itself.
Its good to hear your having some fun and if you have any suggestion for improvements then please send and I'll see what I can do. I've just added two new commands for the next version to allow I2C devices to be read/write from Basic.
cheers

Hiya,
Yes, sorry, the random setting of servo IDs wasn't my actual intention - causing Robots to fit is, I understand, tantamount to torture, but was an easy way to demonstrate what I was trying to achieve
Thanks again for the effort in building this and everything else. Shall be playing with Robobuilderlib this evening I think. May even dust out the corner of my brain which holds my Lisp knowledge, I don't think it's been touched since my 2nd year at Uni about 13 years ago!

New version of BASIC with the update to SERVO is now available for download. If you do download, try this out:
This turns the LIGHTS on back of the robot into a distance meter, light full on - nothing ahead, but as an object approaches they go out.
For more complex demos -

My current favorite is the mirror moves.
cheers
- Code: Select all
10 LET P=$PSD
20 LIGHTS P-10
30 GOTO 10
