twsi – two–wire serial interface (TWSI) and inter–integrated circuit
bind –a #² /dev|
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 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.|
10–bit addressed devices are not supported. |
No slave mode.
Setting the bus rate is not supported.
