NAME
twsi – two–wire serial interface (TWSI) and inter–integrated circuit (I⁲C) interface

SYNOPSIS
bind –a #⁲ /dev
/dev/twsi*

DESCRIPTION
The twsi device serves a one–level directory containing one file per TWSI or I⁲C bus. Bytes written are transmitted on the bus; bytes received from the bus are queued and delivered 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.
