Definition: GPIO.h:23
-[GPIO pin]
uint8_t pin()
Returns the pin number.
-[GPIO isInput]
bool isInput()
Returns true if the GPIO pin is configured as an input.
-[GPIO state]
BOOL state()
Returns the state of the GPIO pin.
hw.h
Hardware interface abstraction layer.
BOOL
bool BOOL
A Boolean value.
Definition: runtime.h:60
+[GPIO count]
uint8_t count()
Returns the total number of GPIO pins available.
NXObject
The base class for objects in the Foundation framework.
Definition: NXObject.h:21
id
