DlnGpioPinPulldownEnable() Function

The DlnGpioPinPulldownEnable() function activates an embedded pull-down resistor for the specified pin. For more information, read Pull-up/Pull-down Resistors.

Syntax

C/C++

DLN_RESULT DlnGpioPinPulldownEnable(
   HDLN handle, 
   uint16_t pin
);

Parameters

handle: A handle to the DLN-series adapter.
pin: The number of the pin that you want to configure.

Return Value

DLN_RES_SUCCESS: The function successfully activated the pull-down resistor.
DLN_RES_INVALID_PIN_NUMBER: The pin number is not valid. Use the DlnGpioGetPinCount() function to find the maximum possible pin number.
DLN_RES_COMMAND_NOT_SUPPORTED: The DLN adapter does not support pull-down resistors.

Remarks

DLN-1 and DLN-2 adapters do not support pull-down resistors.

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