Abstract
This system uses the company Sunplus SPCE061A 16 SCM as a main control unit, the stepper motor sport as a driver circuit, 1 X8 keyboard input system, to work through the system of digital information. The system of the first working process in the digital display of the operation of a message through the choice of keyboard function keys and number keys enter SCM, the system sent a signal to the motor controller stepper motor control of the action, Cou national anthem at the same time, through the drive pulley Flag-raising and completion of Xiangqi. Flag movements in real time and displayed the national flag high, and adjustable rate movements flag,the national flag will automatically stop at designated locations.
