2 Overview of Linux kernel SPI support5 02-Feb-20127 What is SPI?8 ------------9 The "Serial Peripheral Interface" (SPI) is a synchronous four wire serial12 standardization body. SPI uses a host/target configuration.14 The three signal wires hold a clock (SCK, often on the order of 10 MHz),17 clocking modes through which data is exchanged; mode-0 and mode-3 are most22 SPI hosts use a fourth "chip select" line to activate a given SPI target24 in parallel. All SPI targets support chipselects; they are usually active[all …]
