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
Context
