NAME
iic -- I2C generic i/o device driver
SYNOPSIS
device iic
DESCRIPTION
The iic character device driver provides generic i/o to any iicbus(4)
instance. In order to control I2C devices, use /dev/iic? with the fol-
lowing ioctls:
Ioctl Description
I2CSTART send start condition to the specified device (with 7-bit
address) on the bus
I2CSTOP send stop condition to the bus
I2CRSTCARD reset the bus
You may also use read/write routines, then I2C start/stop handshake is
managed by the iicbus system.
