The i2ctemp.c example on our FTP site
(ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7500-linux/samples/i2ctemp.c) will not
work on the TS-7500 as the temp sensor on the TS-752 is SPI. It is however a
generic example of using the I2C hardware in the Cavium CPU. We attempted to
use the Linux kernel interface to I2C however it will not even communicate
correctly with our I2C temp sensor.
This sample code is going to be the most efficient way of interfacing with I2C
unless you want to bit-bang the data out of DIOs which will be much slower
since you have to go through the SBUS to access the DIO pins.
