class	BCM2835_Config
	Use to configure BCM2835 specific parameters. More...

Enumerations
enum	FunctionSelectType { Input = 0x00, Output = 0x01, Alternate0 = 0x04, Alternate1 = 0x05, Alternate2 = 0x06, Alternate3 = 0x07, Alternate4 = 0x03, Alternate5 = 0x02, FSEL_MASK = 0x07 }
	Prior to using a GPIO pin it requires to get defined for its use as input, output or one of the alternative functions. More...

enum	PullUpDownType { PUD_OFF = 0x00, PUD_DOWN = 0x01, PUD_UP = 0x02 }
	Pins configured as input can make use of internal pull up or down resistors. More...

Functions
bool	IsGPIOInitialized ()
	Returns the status of the initialisation of the GPIO part of the library. More...

void	FunctionSelectPin (unsigned char pin, FunctionSelectType mode)
	Use FunctionSelect() to configure the mode of a BCM2835 pin. More...

void	WritePin (unsigned char pin, unsigned char value)
	Sets or clears a pin configured to be an output. More...

void	SetPin (unsigned char pin)
	Sets a pin configured as output to 1. More...

void	ClearPin (unsigned char pin)
	Resets a pin configured as output to 0. More...

void	SetPullUpDown (unsigned char pin, PullUpDownType pud)
	Enables or disables the BCM2835 internal pull -up or -down resistors for a pin configured as an input. More...

unsigned short	ReadPin (unsigned short pin)
	Reads the value of an (input) pin. More...
