My electronic experience
Somehow and somewhat, I graduted for an electical (communicaion) engineer. For now, I 'm a web developer.
To remember what I have done, it is a good chance to summasize here.
1. A robot arm using servo motor and AVR microcontroller, a student traning project.
2. A robot arm using DC motor and microcontroller, a graduate project.
-Comming soon,
3. A roller break tester project, my old company work.
4. A web cam publisher
5.ARM7,
6. ARM9,An Embedded Linux Project, my another old company work.
This website is about cnc (Computer Numerical Control). There are many subjects on cnc, motion control is the basic of this kind of this machine. The motion control is consists of command intrepreter, path generation and motion control. In order to build some motion control system,you need a real-time system including another non-realtime work together , graphic user interface, file handling, Input/ Output control. A system that meet these requirement may be a group of many processor module running it job, and work together, or you can build this system using single cpu and real-time operating system
The author would like to share knowledge about cnc technology. In the beginning of learning, it very hard to find any reference for cnc development. The real-time os play an important role in electronic and computing industrial. You can reserse real-time behavious for time-critical and display the system status in the same time using only single cpu ;) Today, professional embedded system is mainly implemented using rtos (or embedded operating system) .
