Subject: Re: JOY-STICK for BBC Micro
Hi Mick!
Well, most games using joysticks did assume analogue ones, so it's
hardly a BBC software problem. Digital joysticks were quite rare, and
how to wire one up I'm not sure - I've sent a copy of this reply to the
BBC micro mailing list (see
http://www.nvg.ntnu.no/bbc/betresource.shtml#mail if your not currently
subscribed), so maybe someone there can help.
A simple and more explicit way to test your wiring is to write a short
BASIC program to repeatedly print the values of ADVAL(0), ADVAL(1),
ADVAL(2), ADVAL(3) and ADVAL(4).
The first should show the state of the fire button(s), while the last
four are measurements of the movements in X and Y directions for the two
joysticks.
See page 202 on ADVAL in the BBC User's Guide, found in the
documentation section of "The BBC Lives!". (The page number in your
paper copy may vary.)
