TWSI(3) TWSI(3) NAME twsi - two-wire serial interface (TWSI) and inter-integrated circuit (I²C) interface SYNOPSIS bind -a #² /dev /dev/twsi* DESCRIPTION The twsi device serves a one-level directory containing one file per TWSI or I²C bus. Bytes written are transmitted on the bus; bytes received from the bus are queued and deliv- ered by reading. Seeking to a given offset before reading or writing causes the twsi device to use that offset as a TWSI slave address for a subsequent read(2) or write call.
