<br>
GPIO, SPI, and I2C Control from Userspace, the True Linux Way</p>

Abstract<br>
<br>
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.<br>
<br>
In this talk I'll present the basics of each communication method, and
its generic userspace interface that Linux provides.</p>
