- @defgroup pfleury_ic2master I2C Master library
- @code #include <i2cmaster.h> @endcode
-  
- @brief I2C (TWI) Master Software Library
-
- Basic routines for communicating with I2C slave devices. This single master 
- implementation is limited to one bus master on the I2C bus. 
-
- This I2c library is implemented as a compact assembler software implementation of the I2C protocol 
- which runs on any AVR (i2cmaster.S) and as a TWI hardware interface for all AVR with built-in TWI hardware (twimaster.c).
- Since the API for these two implementations is exactly the same, an application can be linked either against the
- software I2C implementation or the hardware I2C implementation.
-
- Use 4.7k pull-up resistor on the SDA and SCL pin.
- 
- Adapt the SCL and SDA port and pin definitions and eventually the delay routine in the module 
- i2cmaster.S to your target when using the software I2C implementation ! 
- 
- Adjust the  CPU clock frequence F_CPU in twimaster.c or in the Makfile when using the TWI hardware implementaion.
-
- @note 
-    The module i2cmaster.S is based on the Atmel Application Note AVR300, corrected and adapted 
-    to GNU assembler and AVR-GCC C call interface.
-    Replaced the incorrect quarter period delays found in AVR300 with 
-    half period delays. 
-

- @par API Usage Example
-  The following code shows typical usage of this library, see example test_i2cmaster.c
-
- @code
-
- #include <i2cmaster.h>
-
-
- #define Dev24C02  0xA2      // device address of EEPROM 24C02, see datasheet
-
- int main(void)
- {
-     unsigned char ret;
-
-     i2c_init();                             // initialize I2C library
-
-     // write 0x75 to EEPROM address 5 (Byte Write) 
-     i2c_start_wait(Dev24C02+I2C_WRITE);     // set device address and write mode
-     i2c_write(0x05);                        // write address = 5
-     i2c_write(0x75);                        // write value 0x75 to EEPROM
-     i2c_stop();                             // set stop conditon = release bus
-
-
-     // read previously written value back from EEPROM address 5 
-     i2c_start_wait(Dev24C02+I2C_WRITE);     // set device address and write mode
-
-     i2c_write(0x05);                        // write address = 5
-     i2c_rep_start(Dev24C02+I2C_READ);       // set device address and read mode
-
-     ret = i2c_readNak();                    // read one byte from EEPROM
-     i2c_stop();
