Use the GPIO Interface functions to control and monitor the GPIO module of a DLN-series adapter.
General pin information:
- DlnGpioGetPinCount()
Retrieves the number of pins that can be assigned to the GPIO module.
- DlnGpioPinEnable()
Assigns a pin to the GPIO module.
- DlnGpioPinDisable()
Unassigns a pin from the GPIO module.
- DlnGpioPinIsEnabled()
Retrieves whether a pin is connected to the GPIO module.
- DlnGpioPinSetDirection()
Configures a pin as a digital input or output.
- DlnGpioPinGetDirection()
Retrieves whether a pin is configured as a digital input or output.
- DlnGpioPinSetOutVal()
Defines a value on the output pin.
- DlnGpioPinGetOutVal()
Retrieves the output value configured to the pin.
- DlnGpioPinGetVal()
Retrieves the actual value on the I/O line.
Event functions:
- DlnGpioPinSetEventCfg()
Configures event generation for a pin.
- DlnGpioPinGetEventCfg()
Retrieves event generation configuration for a pin.
- DlnGpioPinGetSupportedEventTypes()
Returns the list of the event types available for a pin.
Debounce filter functions:
- DlnGpioPinDebounceEnable()
Enables the Debounce Filter on a pin.
- DlnGpioPinDebounceDisable()
Disables the Debounce Filter on a pin
- DlnGpioPinDebounceIsEnabled()
Determines whether the Debounce Filter is enabled on a pin.
- DlnGpioSetDebounce()
Configures the debounce interval (the minimum duration of pulses to be registered).
- DlnGpioGetDebounce()
Retrieves the debounce interval value.
Open Drain mode functions:
- DlnGpioPinOpendrainEnable()
Enables the Open Drain mode on a pin.
- DlnGpioPinOpendrainDisable()
Disables the Open Drain mode on a pin.
- DlnGpioPinOpendrainIsEnabled()
Determines whether the Open Drain mode in enabled on a pin.
Pull-up/Pull-down resistors functions:
- DlnGpioPinPullupEnable()
Enables the pull-up resistor on a pin.
- DlnGpioPinPulldownEnable()
Enables the pull-down resistor on a pin.
- DlnGpioPinPullupDisable()
Disables the pull-up resistor on a pin.
- DlnGpioPinPulldownDisable()
Disables the pull-down resistor on a pin.
- DlnGpioPinPullupIsEnabled()
Determines whether the pull-up resistor is enabled on a pin.
- DlnGpioPinPulldownIsEnabled()
Determines whether the pull-down resistor is enabled on a pin.
