Communication

I2C lib that supports bit banging and hardware support
Tiny and lightweight I2C library for master mode only. It features no RAM usage compared to Arduino Wire (210 bytes) and only 500 bytes programming size compared to around 2000 for Wire. Even bit banging mode runs up to 370 kHz I2C clock frequency on a 16 MHz Arduino.
