Hi Karl, I can only speak to the Raspberry Pi 2 kernel, but I2C is supported. For an example how to use it from userland, check out a project I posted on github eighteen months ago, that was for the PiFace RTC. https://github.com/jhowie/FreeBSDPiFaceRTC There are useful routines I created for working with devices on the I2C bus, which you are free to use. They are not RPI2-specific, so they should work on other boards.

Simple omission in the kernel config or something more? -- Karl Denninger karl@denninger.net <mailto:karl@denninger.net> /The Market Ticker/ /[S/MIME encrypted email preferred]/home | help
