IN
Syntax
IN ( expression )
Description
When reading from IN (expression), -1 or 0 will be returned corresponding to the voltage level on the pin numbered expression.
This directive does not change the input/output configuration of the pin.
The ARMmite allows control of 24 pins (0..23), with pins 16..23 shared with the AD pins.
Example
' Set pin 9 as an input
INPUT 9
' Assume an external device has driven pin 9 high
PRINT "The
current value of Input pin 9 is "; IN(9) AND 1
The current value of Input pins is 1
