On Monday, June 27th (TOMORROW), at 18:30, Haifux will gather to hear
Baruch Siach talk about
GPIO, SPI, and I2C Control from Userspace, the True Linux Way
General Purpose Input/Output (GPIO), Serial Peripheral Interface (SPI),
and Inter-Integrated Circuit (I2C), are common methods for digital
communication between electronic components. The Linux kernel, being a
popular choice for embedded solutions, provides a general abstraction
layer for each of those communication methods. Modern Linux kernels also
include drivers for many hardware modules implementing GPIO, SPI, or
I2C. The abstraction layers provide a generic way to communicate with
electronic devices, which is independent from the details of specific
hardware implementation. Each abstraction layer provides API for kernel
code, as well as userspace users.
In this talk I'll present the basics of each communication method, and
its generic userspace interface that Linux provides.
