Basically, if you want something to be an input (like the pressure switch), start with

Input X

where X is the number of the pin you want to make be an input. Likewise, use

Output X

for any pins you want to be outputs (relays, PWMs, etc).

Then, the bit variables inX and outX (pre-defined by the BS2, don't worry about declaring them) will represent the states of these pins. For example:

Output 2
Input 3
out2=0
if (in3=0) then switchIsOff
out2=1
switchIsOff:

Remember, the normal BS2 does NOT use serin/serout for I/O, everything is pin-addressable only. Also, you won't be able to use the Spike relays that we use for FIRST as they are specific to the Isaac32(or 16) controllers.
