TWSI(3)TWSI(3)NAMEtwsi - two-wire serial interface (TWSI) and inter-integrated circuit
bind -a /dev
The twsi device serves a one-level directory containing one file per
TWSI or IC 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
10-bit addressed devices are not supported.
No slave mode.
Setting the bus rate is not supported.
