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 -> port to SAM &(|) ESP8266 targets would have to be considered, yet the lib is not multi-cores approach designed

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
