I2C was initially invented by Philips as a simple 2-wire low-speed communications interface between CPUs and simple peripherals. Used primarily in embedded systems to connect things like I/O devices, it is now used, under various names, by most IC manufacturers on many System-on-chips. This seminar will introduce I2C and the I2Cdev API which allows you to write I2C drivers from userspace in Linux.

The SPI, or Serial Peripheral Interface is a protocol developed by Motorola which has become a defacto standard for short distance communication between CPU and peripherals. Although it can be called by several different names, it is a very common bus on embedded devices. This seminar will introduce SPI generally and SPIdev which is a Linux userspace API to write simple SPI drivers without having to write kernel code.
