Control Path Core Implementation
Structure
The control path core code is implemented in C code and runs on the APU. The main
functions are separated into files so the protocol-core is independent from the interface
input or output and the commands themselves. This allows easier re-use and extension.
Files:
• io_interface (.c/.h)
°
This file contains the communication specific code that implements
getString/sendString
°
The sub-functions here are used to separate the core (cmd_interface) from the
physical communications channel.
°
To port to another communications medium, this is the only file that should be
edited.
