Data Structure Documentation

struct AT24C256

Definition at line 60 of file at24c256.h.

Data Fields
uint8_t	bus
	The I2C bus which the device is connected to.

Function Documentation

void AT24C256_setup	(	AT24C256 *	target,
		uint8_t	i2c_number,
		uint8_t	address
	)

Initalizes the slave device and populates data structure variable.

Note

The relavent I2C port must be setup before this is called

Parameters

target	Pointer to the MPU6050 data structure
i2c_number	The number of the peripheral port connected, typically I2C_1 or I2C_2
address	The slave address of the device MPU_DEVICE_ADDRESS or MPU_DEVICE_ADDRESS_ALTERNATE

Returns

0 if setup was ok, 1 if error occured.
