Design And Implementation Of Embedded Teaching Experimental Platform Based On MSP430

With the development of electronicstechnology, curricular courses like microprocessors or embedded systems have been introduced intensively to the major of electrical engineering in universities. Most of these courses emphasize basic principles and theories, supporting experiments, however, are not enough to form a system. Based on the above fact, the assay designs and develops a teaching & experimenting embeddedplatform based on MSP430 microprocessor. Possessing abundant functional modules and interfacing resources, the platform is fit for both beginners and veterans. The platform combines traditional bit control technique with MPY and DMA technique in digital signal processing, approximating the high-end DSP, ARM embedded system platform, meeting the needs of fundamental teaching and products designing.According to the abundant resources of the 430 microprocessor, the essay accomplishes the hardware design of different modules, and the debugging of relevant software. The MCU of the platform is 16-bit ultra-low power-consumption microprocessor MSP430F169. It integrates modules including input keyboard, display, real-time clock, data sampling, communication, data storing, file managing. The platform involves in monobus communicating, UART communicating, I2C bus communicating, SPI bus communicating, infrared communicating, USB file managing, DMA technique, etc. It can implement digital signal processing algorithm like FFT algorithm and FIR filter. Students can master the inner structure and the operating principles of the MCU, learn common hardware interfaces, communicating protocols, and lay the foundation of learning high-end embedded system platform like DSP and ARM.The teaching & experimenting platform may be adapted to teaching aids as well as developing tools, appropriate for undergraduates, electrical engineering technicians and fans of embedded systems. The embedded teaching & experimenting expects wide use in teaching, and may boost the innovational capacity of the undergraduates to some extent.
