This library was created to make communication with I2C devices from C language. Up to know it has work fine for in Raspberry Pi boards (and similar ones!).

Contents
Usage
int i2c_dev_open(struct i2c_dev *dev, int adapter);
int i2c_dev_close(struct i2c_dev *dev);
int i2c_dev_write(struct i2c_dev *dev, uint8_t *buf, int n);
int i2c_dev_read(struct i2c_dev *dev, uint8_t *buf, int n);
int i2c_dev_wrrs(struct i2c_dev *dev, uint8_t *wbuf, int wn, uint8_t *rbuf, int rn);
Set Up I2C device
int i2c_dev_open(struct i2c_dev *dev, int adapter);
Close I2C device
int i2c_dev_close(struct i2c_dev *dev);
Write to device
int i2c_dev_write(struct i2c_dev *dev, uint8_t *buf, int n);
Read from device
int i2c_dev_read(struct i2c_dev *dev, uint8_t *buf, int n);
Combined Write/Read
int i2c_dev_wrrs(struct i2c_dev *dev, uint8_t *wbuf, int wn, uint8_t *rbuf, int rn);
