+
+ @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.
+
+ @author Peter Fleury pfleury@gmx.ch http://jump.to/fleury

+ @par API Usage Example
+ The following code shows typical usage of this library, see example test_i2cmaster.c
+

+
+ #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();
