+ @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. 
+

+     i2c_start_wait(Dev24C02+I2C_WRITE);     // set device address and write mode

+     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
