大学毕业设计作品：出租车计价器的设计：以AT89S52单片机为中心，通过金属传感器来测距，实现对出租车的计价统计。结合语音芯片ISD4004，时钟芯片DS1302，功放模块LM386N组成语音时间控制系统，最后通过液晶显示模块LCD12864显示单价、路程、总价、时间等。本系统可以实现单价、起步价、白天价、夜间价的显示和时间的修改。AT89S52通过P0口与外部语音报价电路相连，可以实现语音报价功能。-Graduated from college design work: the design of a taxi meter: The AT89S52 microcontroller as the center, ranging through the metal sensor to achieve statistical valuation of the taxi. Combination of voice chip ISD4004, clock chip DS1302, composed of voice amplifier module LM386N-time control system, the final adoption of liquid crystal display module LCD12864 show unit price, distance, total price and time. This system can achieve unit price, starting at daytime price, prices shown at night and the time changes. AT89S52 through the P0 port with an external circuit connected to voice offer, you can offer voice functionality.

MSC1210中文资料--内核兼容8051的MSC1210单片机，具有高性能ADC、片内存储器以及Flash编程应用等功能。实际应用系统往往需要进行高精度的测量，同时还必须进行实时快速控制，提高其开发效率。为此人们常采用高精度A/D芯片加带ISP开发功能的单片机系统来实现。德州仪器（TI）的MSC1210单片机解决了上述问题。它集成了一个增强型8051内核、高达33 MHz的时钟周期、8路24位高精度∑-△A/D转换器、Flash存储器等-MSC1210 Chinese data- 8051 MSC1210 microcontroller core compatible with high-performance ADC, on-chip Flash program memory and application functions. Practical applications often require high-precision measurements, but also the need for real-time fast control, to improve their development efficiency. To do this people often use high-precision A/D chip increases with ISP microcontroller system development function to achieve. Texas Instruments (TI) of the MSC1210 microcontroller to solve the above problems. It integrates an enhanced 8051 core, up to 33 MHz clock cycle, 8-channel 24-bit high-precision Σ-△ A/D converter, Flash memory, and so on ... ...
