DlnGpioPinGetEventCfg() Function

The DlnGpioPinGetEventCfg() function retrieves the current event configuration for the specified pin. For more information, read Digital Input Events.

Syntax

C/C++

DLN_RESULT DlnGpioPinGetEventCfg(
   HDLN handle, 
   uint8_t pin, 
   uint8_t* eventType,
   uint16_t* eventPeriod
);

Parameters

handle: A handle to the DLN-series adapter.
pin: A number of the pin that you want to check.
eventType: A pointer to an unsigned 8-bit integer. After the function execution, this integer is set to the current event configuration of the pin.
eventPeriod: A pointer to an unsigned 16-bit integer. After the function execution, this integer is set to the interval at which the specified events occur.

Return Value

DLN_RES_SUCCESS (0x00): The function retrieved the event configuration successfully.
DLN_RES_INVALID_PIN_NUMBER (0xAB): The pin number is not valid. Use the DlnGpioGetPinCount() function to find the maximum possible pin number.

Remarks

GPIO events are by the DLN-1 adapters.

The DlnGpioPinGetEventCfg() function is declared in the dln_gpio.h file.
