Dear everybody,
I work with codevisionavr,I'd like to know,what is the diffrence 
between I2C & TWI?,by this question I mean the two diffrent tabs in 
codewizardavr labled I2C & TWI.
thanks!

My guess , never having read anything, is that TWI might stand for 
3-wire-interface.

such as SPI

I2C is a 2-wire interface, and funnily enough it's usually that one 
which is anonymised, as it is ( or was ) a Philips patent.

Good try.  TWI == two wire interface == i2c == smbbus == ?

TWI is two-wire interface. It is pretty much the same as I2C but developed 
by a different company.
