More recently,I thought that the time had come to review the choice of microcontroller. We traditionally used8-bit processors because modern devices have versatile peripherals and sophisticated embedded emulation and are quite powerful enough for most applications.Then the Texas Instruments MSP430caught my eye.A problem with8-bit microcontrollers is that8bits are too few for addresses,which are typically16bits long, and this means that data and addresses cannot be treated on an equal footing.In contrast, the MSP430has a uniform,16-bit architecture throughout:The address bus,data bus,and registers in the CPU are all16bits wide.The CPU has a modern design with plenty of registers,most of which can be used equally for data or addresses.It has a small instruction set with orthogonal addressing and an ingenious constant generator,which is used to emulate many operations that would otherwise need their own,distinct instructions.In many ways these features make the16-bit MSP430simpler than a typical8-bit processor.xii PrefaceOf course an elegant architecture does not generate many sales in the real world.More important are the range of peripherals and development tools.The MSP430offers the usual selection of peripherals plus some less common modules,including sigma–delta analog-to-digital converters and operational amplifiers.Some devices include hardware multipliers and digital-to-analog converters,which provide a complete signal chain(although,of course,Texas Instruments also offers an enormous range of digital signal processors).There is a choice of two free development environments(always an important considerationin education).One is IAR Embedded Workbench,which is available for a wide range of microcontrollers.Another,Code Composer Essentials,is produced by Texas Instruments itself.A third option is the GCC toolchain for MSP430at .I have not yet mentioned the major selling point of the MSP430,which is its low power consumption.Many microcontrollers are based on long-established designs withlow-power modes grafted onto them.This means that returning to full power from alow-power mode is often awkward and in some cases is virtually a reset operation.The MSP430is refreshingly different because it was designed from the outset for low-power operation.Entry to low-power modes and exit from them is straightforward,supported by a versatile clock system.For example,the clock module includes a digitally controlled oscillator that restarts at full speed from a low-power mode in less than1s in newer devices.In many applications the MSP430is put into a low-power mode,from which it is awakened by interrupts.These automatically restore full power for the interrupt service routine and return the processor to low power when it hasfinished.No extra code is needed for this:It is an intrinsic part of the interrupt mechanism.Most peripherals are designed for low power,although this can sometimes make them a little more complicated than would otherwise be necessary.The main point is that low-power modes are easy to use.The quality of the data sheets and user’s guides is another issue in education and those for the MSP430arefine.Unfortunately one item was missing in the area of documentation:a suitable textbook in English.I wrote this book tofill the gap.OutlineMost textbooks on microcontrollers follow one of two approaches.Thefirst is to present a sequence of projects to explore successive aspects of the device.I think that this works well for simpler architectures,notably the8-bit PICs,because it enables the reader to write functioning programs rapidly.This always feels good.Unfortunately I am not sure that it works as well for more advanced peripherals,which need considerable explanation before the reader can learn to use them fully.Preface xiii The alternative approach is to describe each module in the microcontroller fully and in turn,starting with the CPU and instruction set and working out to the peripherals.This makes for a well-organized reference book but can be tedious as a textbook.I tried to steer a course between these two.My inspiration is Kernighan and Ritchie’s The C Programming Language,which starts with a“Tutorial Introduction”before exploring the language systematically in subsequent chapters.I think that it takes rather more introduction to a microcontroller so the“simple tour,”which is my equivalent to the tutorial,does not start until Chapter4.Before that,thefirst chapter contains a general introduction to embedded systems and microcontrollers.This sets the scene for Chapter2, which focuses on the MSP430and gives a broad view of its features.I include a chapter on hardware and software for developing applications,which I hope will be particularly useful for readers who are new to microcontrollers.It also contains some reminders of features of the C language that are more prominent in programs for microcontrollers than desktop computers—bitfields for instance.This leads into the tour,which runs through some simple programs to illustrate input and output,the inevitableflashing LEDs,and an introduction to one of the timers(the MSP430has several).The remainder of the book provides a more systematic description of the MSP430.I start with the CPU and instruction set,and show how the constant generator is used to provide further“emulated”instructions.The clock system is also described in this chapter.It is followed by Chapter6on subroutines,interrupts,and low-power modes.I already mentioned that a major feature of the MSP430is the way in which low-power modes are handled automatically when interrupts are serviced.Subsequent chapters are concerned with the most widely used peripherals.Chapter7on digital input and output starts with the usual parallel ports and goes on to describe liquid crystal displays,which many MSP430s can drive directly.There is a wide selection of timers in the MSP430,which are covered in the next chapter.This is followed by a lengthy chapter on analog input and output.The MSP430offers many peripherals for analog-to-digital conversion,ranging from a simple comparator to a16-bit sigma–delta module.I do not think that you can use any of these without some understanding of their characteristics,which explains the length of this chapter.Some MSP430s include operational amplifiers and digital-to-analog converters,which I described briefly.Thefinal long chapter is on communication.I cover only three types of communication—serial peripheral interface,inter-integrated circuit bus,and asynchronous—but there are several peripherals for these in different variants of the MSP430,so there is a lot to explain.xiv PrefaceThe very last chapter provides an introduction to the MSP430X,an extended architecture with a20-bit address bus that can handle1MB of memory.There is also an appendix to take the reader through the steps of editing,building,and debugging thefirst project, which can sometimes be a frustrating experience.Ifind it annoying when books contain large chunks copied directly from data sheets and have tried to avoid this.You cannot hope to program a microcontroller without the data sheet at your side.Having said that,I start by going through each bit of the registers that control the peripherals used for the early programs.The idea is to explain how a typical peripheral is configured.After that I become more selective and concentrate on the overall function of the peripheral ually I pick out a few details that I think need extra explanation but skip the more mundane aspects.They are in the example programs inany case.I include links to many of Texas Instruments’application notes because I can see no point in repeating material that has been thoroughly explained already.Ifind that many students are strangely reluctant to use this valuable resource.There are a few reminders about code examples for the same reason.C or Assembly Language?Most small microcontrollers are now programmed using the C language so the question might seem redundant.In fact often columns in newletters on embedded systems often carry articles with titles such as“Is Assembly Language Dead?”However,the answer seems to be clearly that assembly language is not dead for small microcontrollers,such as the MSP430.Most code is written in C but you may occasionally need to write a subroutine in assembly language to perform an operation that cannot be written out directly in C.Two examples are operations that require bitwise rotations rather than shifts and calculations that can be done more efficiently by exploiting special instructions of the CPU,such as binary-coded decimal arithmetic.Intrinsic functions often avoid the need for assembly language but not always.More important,assembly language is often needed for debugging and this is the most compelling reason for describing it in a textbook.Small microcontrollers typically spend much of their time interacting with hardware by manipulating the registers that control the peripherals.Debugging may require stepping through lines of assembly language to check each step.You have to look at the manual to check the details of each instruction,but it helps to have a general idea of how the assembly language works.Preface xv From a pedagogical point of view,assembly language is useful to illustrate the architecture of the processor.In fact the MSP430is simple enough that you can explore the thinking behind the design of the instruction set.Besides,assembly language can be fun(in small doses).My approach is to develop thefirst,simple programs in Chapter4using both C and assembly language to show the relation between them.However,C dominates by the end of the chapter.Assembly language makes a strong showing in the next two chapters,which cover architecture,subroutines,and interrupts,including a section on mixing C and assembly language.Almost all remaining programs are in C,with assembly language reappearing only briefly for a function to convert numbers to binary-coded decimal.The listings in the text are read directly from the programs that I tested.Companion Web SitePlease visit the companion Web site for this book at/companions/9780750682763and download the programs used as examples in the book.These programs were read into the text of the book from the workspaces that I used for testing,which means that the downloadedfiles should match the book perfectly.Links are also provided for data sheets,user’s guides,and development tools.Solutions to the odd-numbered examples are freely available on the companion Web site but the remaining solutions are offered only to instructors. AcknowledgmentsIt is a pleasure to thank numerous people who have helped me in various ways to write this book.Many are from Texas Instruments:Bonnie Baker,Jacob Borgeson,Andreas Dannenberg,Colin Garlick,Thomas Mitnacht,and Robert Owen.I am particularly grateful to Adrian Valenzuela for his comments on thefinal draft.Several engineers from other companies were kind enough to provide advice and assistance:Edward Gibbins and Steve Duckworth from IAR,Tom Baugh of SoftBaugh,Paul Curtis of Rowley Associates,David Dyer of Ericsson and Fernando Rodriguez while he was at Texas Instruments.Finally,I am grateful to colleagues and students at Glasgow University,from whom I have learnt an enormous amount over the years.I’d like to thank Fernando Rodriguez(not the same person who was at Texas Instruments)and David Muir in particular,with both of whom I have run a wide range of projects on embedded systems and microcontrollers—from tutor boxes withflip-flops to the electronic systems of a Formula Student racing car.John Davies,Milngavie。

使用__delay_cycles()函数实现延时,控制LED闪烁频率。
3、编译程序使用MSP430单片机编译器将程序编译成机器码,生成可执行文件。
在编译时,需要注意选择正确的编译器选项和单片机型号。
4、调试程序使用MSP430单片机调试器将可执行文件下载到单片机中,并使用调试器进行调试。
在调试时,可以观察单片机的输出口状态和LED灯的闪烁情况,确保程序正常运行。
随着嵌入式系统的发展,MSP430单片机作为一种低功耗、高性能的微控制器,在各种应用领域中得到了广泛的应用。
为了更好地理解和应用MSP430单片机,我在学习过程中积累了一些经验,现在分享给大家。

transparent to the application.All operations,other than program-flow instructions,are performed as register operations in conjunction with seven addressing modes for source operand and four addressing modes for destination operand.The CPU is integrated with 16registers that provide reduced instruction execution time.The register-to-register operation execution time is one cycle of the CPU clock.Four of the registers,R0to R3,are dedicated as program counter,stack pointer,status register,and constant generator,respectively.The remaining registers are general-purpose registers.Peripherals are connected to the CPU using data,address,and control buses and can be handled with all instructions.instruction setThe instruction set consists of 51instructions with three formats and seven address modes.Each instruction can operate on word and byte data.Table 1shows examples of the three types of instruction formats;Table 2shows the address modes.Table 1.Instruction

operation.An interrupt event can wake up the device from any of the five low-power modes,service the request,and restore back to the low-power mode on return from the interrupt program.The following six operating modes can be configured by software:D Active mode(AM)--All clocks are activeD Low-power mode0(LPM0)--CPU is disabled--ACLK and SMCLK remain active--FLL+loop control remains activeD Low-power mode1(LPM1)--CPU is disabled--ACLK and SMCLK remain active--FLL+loop control is disabledD Low-power mode2(LPM2)--CPU is disabled--MCLK,FLL+loop control,and DCOCLK are disabled--DCO’s dc generator remains enabled--ACLK remains activeD Low-power mode3(LPM3)--CPU is disabled--MCLK,FLL+loop control,and DCOCLK are disabled--DCO’s dc generator is disabled--ACLK remains activeD Low-power mode4(LPM4)--CPU is disabled--ACLK is disabled--MCLK,FLL+loop control,and DCOCLK are disabled--DCO’s dc generator is disabled--Crystal oscillator is stoppedinterrupt vector addressesThe interrupt vectors and the power-up starting address are located in the address range0xFFFF to0xFFC0.The vector contains the16-bit address of the appropriate interrupt-handler instruction sequence.If the reset vector(located at address0xFFFE)contains0xFFFF(e.g.,flash is not programmed),the CPU goes into LPM4immediately after power-up.INTERRUPT SOURCE INTERRUPT FLAG SYSTEM INTERRUPTWORDADDRESS

MSP430BSL enables users to program the flash memory or RAM using a UART serial interface.Access to the MSP430memory via the BSL is protected by user-defined password.For complete description of the features of the BSL and its implementation,see the MSP430Memory Programming User’s Guide,literature number SLAU265.BSL FUNCTION PM PACKAGE PINS RGZ PACKAGE PINSData transmit53--P1.037--P1.0Data receive52--P1.136--P1.1flash memory(Flash)The flash memory can be programmed via the JTAG port,the bootstrap loader,or in-system by the CPU.The CPU can perform single-byte and single-word writes to the flash memory.Features of the flash memory include:D Flash memory has n segments of main memory and four segments of information memory(A to D)of64bytes each.Each segment in main memory is512bytes in size.D Segments0to n may be erased in one step,or each segment may be individually erased.D Segments A to D can be erased individually,or as a group with segments0to n.Segments A to D are also called information memory.peripheralsPeripherals are connected to the CPU through data,address,and control buses and can be handled using all instructions.For complete module descriptions,see the MSP430x4xx Family User’s Guide,literature number SLAU056.oscillator and system clockThe clock system in the MSP430F41x2is supported by the FLL+module that includes support for a32768-Hz watch crystal oscillator,an internal very low-power low--frequency oscillator,an internal digitally-controlled oscillator(DCO),and an8-MHz high-frequency crystal oscillator(XT1).The FLL+clock module is designed to meet the requirements of both low system cost and low power consumption.The FLL+features a digital frequency locked loop(FLL)hardware that,in conjunction with a digital modulator,stabilizes the DCO frequency to a programmable multiple of the watch crystal frequency.The internal DCO provides a fast turn-on clock source and stabilizes in less than6µs.The FLL+module provides the following clock signals:D Auxiliary clock(ACLK),sourced from a32768-Hz watch crystal,a high-frequency crystal,or a verylow-power LF oscillatorD Main clock(MCLK),the system clock used by the CPUD Sub-Main clock(SMCLK),the sub-system clock used by the peripheral modulesD ACLK/n,the buffered output of ACLK,ACLK/2,ACLK/4,or ACLK/8brownout,supply voltage supervisorThe brownout circuit is implemented to provide the proper internal reset signal to the device during power on and power off.The supply voltage supervisor(SVS)circuitry detects if the supply voltage drops below a user selectable level and supports both supply voltage supervision(the device is automatically reset)and supply voltage monitoring(SVM,the device is not automatically reset).The CPU begins code execution after the brownout circuit releases the device reset.However,V CC may not have ramped to V CC(min)at that time.The user must insure the default FLL+settings are not changed until V CC reaches V CC(min).If desired,the SVS circuit can be used to determine when V CC reaches V CC(min).digital I/OThere are seven8-bit I/O ports implemented—ports P1through P7.Port P7is a7-bit I/O port.D All individual I/O bits are independently programmable.D Any combination of input,output,and interrupt conditions is possible.D Edge-selectable interrupt input capability for all the eight bits of ports P1and P2.D Read/write access to port-control registers is supported by all instructions.watchdog timer (WDT+)The primary function of the WDT+module is to perform a controlled system restart after a software problem occurs.If the selected time interval expires,a system reset is generated.If the watchdog function is not needed in an application,the module can be configured as an interval timer and can generate interrupts at selected time intervals.Basic Timer1and Real-Time Clock (RTC)The Basic Timer1has two independent 8-bit timers which can be cascaded to form a 16-bit timer/counter.Both timers can be read and written by software.The Basic Timer1is extended to provide an integrated real-time clock (RTC).An internal calendar compensates for month with less than 31days and includes leap year correction.LCD_A driver with regulated charge pumpThe LCD_A driver generates the segment and common signals required to drive an LCD display.The LCD_A controller has dedicated data memory to hold segment drive mon and segment signals are generated as defined by the mode.Static,2--MUX,3--MUX,and 4--MUX LCDs are supported by this peripheral.The module can provide a LCD voltage independent of the supply voltage via an integrated charge pump.Furthermore it is possible to control the level of the LCD voltage and thus contrast in software.Timer0_A3Timer_A3is a 16-bit timer/counter with three capture/compare registers.Timer_A3can support multiple capture/compares,PWM outputs,and interval timing.Timer_A3also has extensive interrupt capabilities.Interrupts may be generated from the counter

8.3 键盘接口电路
8.3.1 键盘接口慨述
⒈ 按键开关去抖动问题
消除抖动不良后果的方法有硬、软件两种方法: ⑴ 硬件去抖动:利用双稳电路、单稳电路和RC滤波电路 ⑵ 软件去抖动:延时10ms后再确认该键是否确实按下。
⒉ 按键连接方式 可分为独立式按键和矩阵式键盘。
⑴ 独立式按键
独立式按键是各按键相互独立,每个按键占用一根I/O端线, 每根I/O端线上的按键工作状态不会影响其他I/O端线上按键的工作状态,
延时等待方式时,0809 EOC端可不必与80C51相连,而是根据时钟频率计算出 A-D转换时间,每路每次需64个时钟周期,80C51一机周发出2次ALE信号, 因此需要32个机器周期,略微延长后直接读A-D转换值。
