◆ pinMode()

virtual void pinMode ( pin_t  pin,
PinMode_t  mode 
)
inlinevirtualinherited

Set the mode of a given pin.

Note
This function might not be implemented by all subclasses.
Some extended IO types, such as shift registers, can only be used as outputs.
On others, it might be implemented, but it could impact all pins of the IO element. For example, enabling the internal pull-up resistor on an analog multiplexer affects all pins of the mux.
Parameters
pinThe (zero-based) pin of this IO element.
modeThe mode to set the pin to (e.g. INPUT, OUTPUT or INPUT_PULLUP).

Reimplemented in MAX7219< NumChips, SPIDriver >, and ShiftRegisterOutBase< N >.

◆ pinModeBuffered()

virtual void pinModeBuffered ( pin_t  pin,

pure virtualinherited

Set the mode of a given pin in the software buffer.

The buffer is written to the ExtIO device when updateBufferedOutputs is called.

Note
This function might not be implemented by all subclasses.
Some extended IO types, such as shift registers, can only be used as outputs.
On others, it might be implemented, but it could impact all pins of the IO element. For example, enabling the internal pull-up resistor on an analog multiplexer affects all pins of the mux.
