README.md

This repository contains example code (orginiated from and similar to the examples in IgH EtherCAT Master library), written for motion control of two servomotors connected to LS Mecapion L7N servo drives in CSP mode. The codes are extensively commented to facilitate the conversion process to accommodate different setups.
Additionally, in Documentation folder, you will find step-by-step procedures for installing:

• kernel with RTAI patch
• kernel with PREEMPT_RT patch, 3.4.113 and 4.4.162.
• Igh EtherCAT master library

and a few suggestions for improving the real-time properties of PREEMPT_RT.

---

To run the programs, after installing the IgH Master library, copy-and-replace each in the examples folder, and

1. For the user example, in ~/stable-1.5/examples/usr,
   • make clean
   • make
   • ./ec_user_example to run the userspace process.
2. For the RTAI example, in /usr/local/src/ethercat/examples/rtai,
   • make clean
   • make modules
   • insmod ec_rtai_sample.ko to load the kernel module (and start the hard real-time task).
