Classes
class	TwoWire
	An I2C bus: the Arduino Wire API on one of the chip's I2C peripherals (the global Wire on this board). More...

Macros
#define	BUFFER_LENGTH   32
	The smallest size of the receive and transmit buffers, in bytes (they grow on the heap when a transfer needs more).
#define	WIRE_MAX_TX_BUFF_LENGTH   1024U
	The most bytes one transmission (beginTransmission() ... endTransmission()) can hold; write() returns 0 past it.
#define	WIRE_HAS_END   1
	Defined to 1: this Wire has end().

Variables
TwoWire	Wire
	The I2C bus: I2C1 on PC18 (SDA, header H1.2) and PC19 (SCL, H1.1).
