- @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.
-
- @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
-
- @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();
-
- for(;;);
