IDigitalIoDevice

Interface for digital I/O device drivers. Provides methods for reading and writing digital bit values.

Namespace: DeviceBase

Inheritance​

This interface extends IDevice.

Methods​

GetDigitalInputBit​

Reads the current state of a digital input channel.

bool GetDigitalInputBit(int channel);

Parameters:

  • channel — The channel number.

Returns: true if the input is high, false if low.

SetDigitalOutputBit​

Sets the state of a digital output channel.

void SetDigitalOutputBit(int channel, bool value);

Parameters:

  • channel — The channel number.
  • value — true to set high, false to set low.

GetDigitalOutputBit​

Gets the current state of a digital output channel.

bool GetDigitalOutputBit(int channel);

Parameters:

  • channel — The channel number.

Returns: true if the output is high, false if low.

Usage Example​

IDigitalIoDevice digitalDevice = ...;

// Initialize device
digitalDevice.Init(config);

// Read digital input
bool sensorState = digitalDevice.GetDigitalInputBit(0);

// Set digital output
digitalDevice.SetDigitalOutputBit(1, true);

// Read back output state
bool outputState = digitalDevice.GetDigitalOutputBit(1);

// Dispose when done
digitalDevice.Dispose();

Remarks​

  • Digital I/O operates with boolean values representing on/off or high/low states.
  • Input channels are typically read-only from sensors or switches.
  • Output channels can be set and read back for verification.
