Function Documentation

gpio_read()

bool gpio_read ( uint32_t bit )

extern

Reads a GPIO Input.

Reads the value of a GPIO Input

Parameters

bit	Bit to read value of

gpio_set_direction()

void gpio_set_direction ( uint32_t bit, bool direction )

extern

Sets the direction of the GPIO.

Sets the direction of a bit.

This is set to the expected value before the game runs.

Parameters

bit	Bit to set
Direction	False = Input, True = Output

void gpio_write ( uint32_t bit, bool set )

extern

Writes a GPIO output.

Writes the bit to the GPIO controller.

Parameters

bit	Bit to set/clear
