This paper states a multi-task programming course project experiment item of real time operating system VxWorks. The project is an emulator of railway ticket vending machine. Its research background is Wuhan-Guangzhou high speed railway line ticket vending machine. The contents of the paper includes process flow, function design and analysis, data flow analysis, task division and definition, semaphore control application, test results, etc.

Course project experiment plays a very important role in master student embedded system software education. The paper gives the design and implementation solution to a Chinese character text editor for embedded system, including requirement analysis, function design, task division, main process flow, Chinese character process, man-machine interface layout and test results. This course project can be used as a template for embedded system software experiment.
