Field Detail

dev

public FlinkSubDevice dev

Handle to the subdevice within our flink device

Constructor Detail

FlinkGPIO

public FlinkGPIO(FlinkSubDevice dev)

Creates a GPIO subdevice.

Parameters:

dev - handle to the subdevice

Method Detail

setDir

public void setDir(int channel,
                   boolean output)

Sets the direction of a single channel within a GPIO subdevice. Each channel can work as either digital input or output. Channel number must be 0 <= channel < nof available channels.

Parameters:

channel - channel number

output - false = input, true = output

getDir

public boolean getDir(int channel)

Reads the direction of a single channel within a GPIO subdevice. Each channel can work as either digital input or output. Channel number must be 0 <= channel < nof available channels

Parameters:

channel - channel number

Returns:

false = input, true = output

getValue

public boolean getValue(int channel)

Reads the value of a single channel within a GPIO subdevice. Channel number must be 0 <= channel < nof available channels

Parameters:

channel - channel number

Returns:

false = low, true = high

setValue

public void setValue(int channel,
                     boolean value)

Sets the logical level of a single channel within a GPIO subdevice. Channel number must be 0 <= channel < nof available channels

Parameters:

channel - channel number

value - false = low, true = high
