Virtually all evaluation modules -are supported, but a few lines of code need to be added for each new -module to instantiate the right I2C chip on the bus. Obviously, a driver -for the chip in question is also needed. - -Currently supported devices are: - -* TAOS TSL2550 EVM - -For additional information on TAOS products, please see - http://www.taosinc.com/ - - -Using this driver ------------------ - -In order to use this driver, you'll need the serport driver, and the -inputattach tool, which is part of the input-utils package. The following -commands will tell the kernel that you have a TAOS EVM on the first -serial port: - -# modprobe serport -# inputattach --taos-evm /dev/ttyS0 - - -Technical details ------------------ - -Only 4 SMBus transaction types are supported by the TAOS evaluation -modules: -* Receive Byte -* Send Byte -* Read Byte -* Write Byte - -The communication protocol is text-based and pretty simple. It is -described in a PDF document on the CD which comes with the evaluation -module. The communication is rather slow, because the serial port has -to operate at 1200 bps. However, I don't think this is a big concern in -practice, as these modules are meant for evaluation and testing only. |
