hello,
I am trying to use analog multiple switches for multiple function
as
i have 5 buttons on analogpin 0
which returns
left 0
up 1
down 2
right 3
select 4
i want to use select button to change the behaviour of reset of four buttons
i.e if select count is 1
they behave as menu driver moveup, movedown, moveleft, moveright
if select count is 2
they behave as cursor moveup,down left right
if count 3
the buttons increase or decrease the selected value
any help
look at the link in my thread (below) and you will find in the code all you need
To do this, you'll have to decide how the select button works - does pressing it go through the three states in order, or do you hold it down to go to a special state, etc?
For example, if you pressed the button repeatedly to cycle through the states, then code like this would take care of the state switch:
int selectButtonState=1;
...later on...
If (selectButtonPressedSomehow())
{
selectButtonState=selectButtonState+1;
if (selectButtonState>3)
selectButtonState=1;
}
...later on...
if (1==selectButtonState)
{
// do menu driver moveup, movedown, moveleft, moveright
}
if (2==selectButtonState)
{
// dos cursor moveup,down left right
}
if (3==selectButtonState)
{
// do buttons increase or decrease the selected value
}
(note the code can be shorter - this is just to illustrate how to do it simply)
The end result is your select button can have the others do three different states per button
