This paper introduces an experiment system developed as a teaching material to support the lessons related to vibration and earthquake resistance in the fields of civil engineering and architecture. The hardware was composed of an accelerometer, a serial communication interface, an RS232-USB conversion adapter, and a computer. The virtual shaking table in a computer display was controlled by the hand-operated accelerometer. The response of the structure model with multi-degrees of freedom on the shaking table was calculated in real time. The findings were that hands-on experience in controlling the shaking table helps an instinctive understanding of vibration, especially acceleration and seismic intensity. A structure model with different dynamic characteristics can be built easily, so that the effect of properties, such as the natural period and damping constant on the structural motions, can be visualized, helping the understanding of the theory of vibration.

Spi Interface

SPI (Serial Peripheral Interface) is a full-duplex serial communication interface bus. Now, many devices adopt SPI. However, in many other aspects, microcontroller and microprocessor have no SPI interface, data transmission is inconvenient. With the development of FPGA technology, the problem can be solved absolutely by the I/O port of FPGA. In this paper, after introducing the principle of SPI, we designed SPI interface with FPGA and implemented the communication between SPI interface and the device of CRG20 which has a SPI interface. The algorithm of design SPI interface through FPGA is implemented with VHDL. The results of simulation in Quartus II and FPGA simulation are also described. The SPI bus interface modules fulfill the goal demanded.

Error Detecting

In order to improve the management of modern large library, an automatic system is needed to arrange the books. The system uses two-dimensional code recognition technology and microcontroller control technology to achieve the efficient management of library. We choose STC89C52 chip as the core controller and the scanning module in the HR-200 laser two-dimensional code scanner as the external communication port. Data is transmitted by serial communication interface between them. By scanning the two-dimensional code on the books and shelves, we can quickly find out the books in wrong position. In this way we can enhance the efficiency of books management obviously. In comparison with the experimental results, the feasibility and rationality of the design are validated as well as the practicability of the system.
