public interface Gpio
int init(int[] gpio)
gpio - An array defines the directions of GPIO pins. The GPIO direction will be:
GPIO_OUTPUT
GPIO_INPUTint read(int portNum,
boolean[] bValue)
portNum - GPIO port number.bValue - A variable of typeBOOL which receives the value of the GPIO pin.int write(int portNum,
boolean bValue)
portNum - GPIO port number.bValue - The output value.
