Chapter 3
Examples for HPS SoC
This chapter provides several C-code examples based on the Intel SoC Linux built by Yocto project.
These examples demonstrate major features connected to HPS interface on HAN Pilot Platform
such as users LED/KEY, Network Communication. All the associated files can be found in the
directory Demonstrations/SOC of the HAN Pilot Platform System CD. Please refer to Chapter 5
"
Running Linux on the HAN Pilot Platform " from the HAN Pilot Platform Getting Start Guide .
To install the demonstrations on the host computer: Copy the directory Demonstrations into a local
directory of your choice. Intel SoC EDS v18.0 is required for users to compile the c-code project.

Function Block Diagram
Figure 3-1 shows the function block diagram of this demonstration. The users LED and KEY are
connected to the GPIO1 controller in HPS. The behavior of GPIO controller is controlled by the
register in GPIO controller. The registers can be accessed by application software through the
memory-mapped device driver, which is built into Intel SoC Linux.

Block Diagram of GPIO Interface
The HPS provides three general-purpose I/O (GPIO) interface modules. Figure 3-2 shows the block
diagram of GPIO Interface. GPIO[28..0] is controlled by the GPIO0 controller and GPIO[57..29] is
controlled by the GPIO1 controller. GPIO[70..58] and input-only GPI[13..0] are controlled by the
