Arduino Hardware I2C for AVR (plain c) Hardware I2C library for AVR µcontrollers (lib intended for I2C protocols development in c, for easier ports to other µcontrollers)

Notes:

cI2C is written in plain c (intentionally)
cI2C does not use any interrupt (yet, but soon will have to)
cI2C is designed to act as bus Master (Slave mode will be considered in future releases)
cI2C is set to work on AVR targets only
- for other targets, you may use WireWrapper instead (will be using Wire)
- cI2C & WireWrapper libs declare same structures & functions as seen from the outside (switch between libs without changing anyhting but the include)

Usage:

refer to Doxygen generated documentation & example sketches

Examples included:

following examples should work with any I2C EEPROM/FRAM with address 0x50 (yet function to get Chip ID are device dependant (and will probably only work on FUJITSU devices))

ci2c_master_write.ino: Write some bytes to FRAM and compare them with what's read afterwards
ci2c_master_read.ino: Read some bytes in FRAM
ci2c_advanced.ino: Redirecting slave write & read functions (to custom functions following typedef)

Doxygen doc can be generated for the library using doxyfile
