DIO#.INV

Description

Sets or gets the polarity of a bi-directional I/O when configured as a digital input (see DIO#.DIR).

Value	Description
0 - Active high	The digital input state is 1 when voltage is applied to the IO pin
1 - Active low	The digital input state is 1 when voltage is removed from the IO pin

Examples

Usage

When DIO#.DIR = 0 (input) then the corresponding DIO#.INV can be set to change the polarity of the input signal.

Code

--> DIO1.DIR 0

With 24V on DIO1:

--> DIO1.INV 0 //Active high
--> DIO1.STATE
1
--> DIO1.INV 1 //Active low
--> DIO1.STATE
0

With 0V on DIO1:

--> DIO1.INV 0 //Active high
--> DIO1.STATE
0
--> DIO1.INV 1 //Active low
--> DIO1.STATE
1
