Digital I/O

All Digital I/O such as relays, led's, general purpose I/O or virtual I/O are declared with the

digitalport declaration. See module documentation for specific details of the port numbers.

Examples:

digitalport Rly1 1

digitalport Rly2 2

digitalport LedBlue 32

digitalport LedGreen 33

digitalport LedRed 34

digitalport Flag1 100

digitalport Flag2 101

To output to the port just write:

Rly1 = on

LedBlue = on

Rly2 = off

Flag1 = on

There are 64 virtual I/O ports in the range 100 to 163. These are not associated with any real

I/O port, they exist only in the modules memory. Flag1 and Flag2 above are examples of

virtual I/O. They are useful to hold the state of remote I/O, of just as flags to control program

flow.

Analogue I/O

All Analogue inputs are declared with the analogport declaration. See Module documentation

for specific details of the port numbers.

Examples:

analogport TS2 2 ; ext temp sensor

analogport TS1 100 ; on-board temp sensor

analogport PSU 101 ; DC power voltage

Analogue ports do not store any values, so each time you refer to the port a new analogue to

digital conversion is performed.

var Volts

Volts = PSU

Will convert analogue channel PSU and store the result in the variable Volts.
