Button command explanations

Hello,
I didn't find any explanations about BUTTON command, so :
in the help I see
BUTTON Pin,Down,Delay,Rate,BVar,Action,Label
question:
Tell me if I can use this Command for this need.
Assume that somebody depress a DTMF unit, so I am aware of a code is
present looking to the STROBE input of a MT8870 for example.

I need to DO a ONE step (right or left depending of the DTMF code)
and if the guy is maintaining the DTMF strobe... let say after 500 ms
I will continue to send Right or left order(s) to the Servo motor.
and as soon the button is released, I will return to the main routine
waiting for a new DTMF.

Is the button command can help me ?

if fact i do not really understand the meanning of autorepeat and the Action
label interraction.

Thanks in advance for your good support.
Francois

Hi, François

The BUTTON function can be used to look at the StD pin ( 15 or 17 ) ...

BUT, to work properly, this pin must be regularly scanned to see if a tone couple has been detected ... ( same use as IF pin x = 1 THEN ...but "anti rebond" included )

OR use an interrupt if the program must react quickly.

What about TSM , rue des 15 arpents ( or so ...) ???

Hé,hé !!!

Well button may help or not, as Alain said. But i would personnally choose an interrupt routine or a tight loop with some PAUSEUS to do the job. I'm not a fan of this Button command so far...

Any snip of what you tried?
