Power PMAC Trajectory Writer

Overview

This module provides a C-based interface for writing and executing trajectory data to Power PMAC systems using user shared memory. It is designed to integrate seamlessly into Power PMAC projects and supports modular inclusion via Git submodules.

It builds upon the following components:

• ppmac_tcp_server – Handles TCP communication between external clients and the Power PMAC system.
• ppmac_ushm_buffer – Manages shared memory buffers for efficient data exchange between user-space and kernel-space.

Together, these modules enable robust and flexible trajectory control for motion systems powered by Power PMAC.
