2015-05-18 Thread Bernhard Kraft
Hi, For a project I needed to communicate with external hardware via the I2C protocol. I took a look at the existing drivers in the linux kernel source "drivers/i2c/busses". Instead of buying yet another interface dongle (this time for I2C) I decided to use an Arduino with an apropriate sket
