button control

[Alexa Stott]

For each port on your OI, you have px_sw_top, px_sw_trig, px_sw_aux1, and px_sw_aux2 with "x" being the appropriate port number. Each of these corresponds with a button or a trigger on whatever joystick is plugged into the port (trig and top being the most obvious).

Your code should look something like this when you program the buttons:

if(button)
{
     doSomething();
}

...and so on from there.

Remember that buttons are digital devices; they are either on or off (1 or 0, respectively).

To control time, we've always simply defined a static unsigned int to 0 and incremented it for each loop of the processor. It takes a lot of playing around to get the values right. There are other ways to do this, as stated above, but that is one of your options.

Hopefully that helps.
