The paper presents the digital phase measuring instrument based on MSP430 single-chip microcomputer. The instrument adopted the technology of DDS to generate sinusoidal signal, and FPGA to achieve phase difference measurement and polarity judgment. The system is composed of a filtering circuit, a phase shifting network, a shaping circuit, matrix keyboard, LCD display module and the frequency is in the range from 200Hz to 10kHz, the phase difference is in the range of-180°~+180 °, the resolution ratio is 0.1°, the absolute error is less than ±2 °, and the relative error is less than ± 3%.

The NC Teaching Plotter is designed for the practice teaching needs of NC machining, In order to improve current existing practice teaching environment of "many student, less equipment". It explains the NC concept with concise way and demonstrates NC thought by the intuitive operation.In this paper, the design of NC teaching plotter makes interpolation motion between pen and table based on NC program in accordance with the requirement made by user, to draw the graphics by moving the magnet control brush painting through the single chip digital control and the two stepper motor control X, Y two axes feed. The NC teaching plotter which demonstrates more clearly and directly the numerical control idea has high practical value for teaching practice.
