基于MSP430单片机实验板开发.doc

摘 要 随着单片机的广泛使用，通用的单片机外围越来越被广泛的关注，设计一块通用且功能完善的单片机系统成为当今学习、研究、开发、设计的一大热门、项目。 MSP430系列单片机是美国德州仪器（TI）1996年开始推向市场的一种16位超低功耗、具有精简指令集（RISC）的混合信号处理器（Mixed Signal Processor）。称之为混合信号处理器，是由于其针对实际应用需求，将多个不同功能的模拟电路、数字电路模块和微处理器集成在一个芯片上，以提供“单片机”解决方案。该系列单片机多应用于需要电池供电的便携式仪器仪表中强大的处理能力 MSP430 系列单片机是一个 16 位的单片机，采用了精简指令集（RISC）结构，具有丰富的寻址方式（ 7 种源操作数寻址、4种目的操作数寻址）、简洁的27条内核指令以及大量的模拟指令；大量的寄存器以及片内数据存储器都可参加多种运算；还有高效的查表处理指令；有较高的处理速度，在 8MHz 晶体驱动下指令周期为125ns。这些特点保证了可编制出高效率的源程序。 Abstract With the wide use of single chip microcomputer, general MCU periphery has become more and more widely attention, to design a general and functional single-chip microcomputer system become todays learning, research, development, design, a big, project. MSP430 series SCM is the Texas instruments (TI) began in 1996 to market one of the 16 ultra-low power consumption, with a reduced instruction set (RISC) of the Mixed Signal Processor (Mixed Signal Processor). Called the mixed signal processor, it is due to its according to actual application demand, will be a number of different functions of analog circuit, digital circuit module and integrated on a single chip microprocessor, in order to provide \SCM\ solution. This series of single-chip microcomputer applied to need more batteries in portable instruments and meters. Powerful processing ability of MSP430 series MCU is a 16-bit microcontroller, reduced instruction set (RISC) structure is adopted, with abundant way of addressing (7) operand addressing, four destination operand addressing) and concise article 27 kernel orders and a large amount of simulation instruction; Plenty of registers and data storage is available to participate in a variety of operations; And efficient look-up table processing instructions; Have higher processing speed, and in the instruction cycle driven by 8 MHZ crystal of 125 ns. These features ensure the source program can be compiled for high efficiency. This experiment include MSP430 minimum system circuit, water lamp circuit, digital tube
