TWSI(3)                    Library Functions Manual                    TWSI(3)



NAME
       twsi  -  two-wire  serial interface (TWSI) and inter-integrated circuit
       (Iâ²C) interface

SYNOPSIS
       bind -a #â² /dev
       /dev/twsi*

DESCRIPTION
       The twsi device serves a one-level directory containing  one  file  per
       TWSI  or Iâ²C bus.  Bytes written are transmitted on the bus; bytes re‐
       ceived 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.

FILES
       #â²/twsi*

BUGS
       10-bit addressed devices are not supported.

       No slave mode.

       Setting the bus rate is not supported.
