1 Kernel driver i2c-taos-evm
3 Author: Jean Delvare <khali@linux-fr.org>
5 This is a driver for the evaluation modules for TAOS I2C/SMBus chips.
6 The modules include an SMBus master with limited capabilities, which can
7 be controlled over the serial port. Virtually all evaluation modules
8 are supported, but a few lines of code need to be added for each new
9 module to instantiate the right I2C chip on the bus. Obviously, a driver
10 for the chip in question is also needed.
12 Currently supported devices are:

23 In order to use this driver, you'll need the serport driver, and the
24 inputattach tool, which is part of the input-utils package. The following
25 commands will tell the kernel that you have a TAOS EVM on the first
29 # inputattach --taos-evm /dev/ttyS0
35 Only 4 SMBus transaction types are supported by the TAOS evaluation
42 The communication protocol is text-based and pretty simple. It is
43 described in a PDF document on the CD which comes with the evaluation
44 module. The communication is rather slow, because the serial port has
45 to operate at 1200 bps. However, I don't think this is a big concern in
46 practice, as these modules are meant for evaluation and testing only.
