again button command

Archiver

Hello stampers

When I use multiple button commands to contol multiple inputs, do I have to
define a dedicated "workspace variable" for each button command or can they
share the same variable.

Thanks

Michel

Scanning multiple BUTTON commands is a bit tough. Below is a small subroutine
that will let you scan and debounce four inputs (the program assumes inputs
are active low -- remove the tilde [noparse][[/noparse]bitwise invert] operator if your inputs
are active high).

btnsIn VAR InA ' four inputs, pins 0 - 3
btns VAR Nib ' debounced inputs
x VAR Nib ' loop counter


GetButtons:
btns = %1111 ' enable all four inputs
FOR x = 1 TO 10
btns = btns & ~btnsIn ' test inputs
PAUSE 5 ' delay between tests
NEXT
RETURN
