Hi Freaks,
Are there any good links/sites that compare TWI,SPI,UART,I2C,RS485,GPIB and Ethernet? As in when to use what protocol? Thanks.

TWI is basically I2C with a few things not implemented.

Usually what you need to use is dictated by what you have to connect to. If you have to interface to some measurement device (scope, bench multimeter for example) that uses GPIB; or want to use a D/A converter that has an SPI interface etc etc

So in other words, is speed and distance the only two criteria used to select a specific protocol? I mean all of them can be set up as a master/slave configuration so the protocol should be same, right? (poll slave, set priorities, block slaves,etc.)
