Introduction to SPI and SPIdev
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.
