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 than1␮s 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。

MSP430教程14MSP430单片机ADC12模块

MSP430教程14MSP430单片机ADC12模块MSP430单片机的ADC12模块是一个12位的模数转换器，用于将模拟电压转换为数字值，以供单片机内部处理。

ADC12模块是MSP430单片机中最常用的外设之一，可以用于各种应用，如模拟传感器读取、电量计算等。

ADC12模块的主要特点包括：1.12位的精度，可以将电压精确转换为4096个不同的数字值。

2.可以配置为单通道或多通道模式，允许同时转换多个模拟通道的电压。

3.支持多种转换触发方式，如手动触发、定时触发、比较触发等。

4.可以配置不同的参考电压源，以适应不同的应用场景。

5.内置温度传感器和内部参考电压源，方便温度和电压的测量。

在使用ADC12模块之前，需要进行一些初始化配置。

首先，需要设置参考电压源，可以选择使用外部引脚输入的参考电压，或者使用内部参考电压。

其次，需要选择转换触发源，可以选择手动触发或定时触发等。

还可以选择转换结果的存储位置，可以存储在内存中，也可以存储在DMA传输缓冲区中。

在实际使用中，可以通过编程设置ADC12的参数并启动转换。

转换完成后，可以通过查询标志位或中断方式来获取转换结果。

获取结果后，可以进行进一步的处理，如计算实际电压值或进行比较判断等。

以下是一个简单的示例代码，演示了如何使用ADC12模块进行模拟电压转换：```c#include <msp430.h>void init_ADC12//设置参考电压为内部2.5V参考源REFCTL0=REFMSTR，REFVSEL_2，REFON;//设置为单通道模式，使用A0通道ADC12CTL0=ADC12ON，ADC12SHT0_8，ADC12MSC;ADC12CTL1=ADC12SHP;//使用采样保持模式ADC12MCTL0=ADC12INCH_0，ADC12VRSEL_1;//设置输入通道为A0，使用2.5V参考电压//选择转换触发源为软件触发ADC12CTL0，=ADC12ENC，ADC12SC;void main(void)WDTCTL=WDTPW，WDTHOLD;//停用看门狗定时器while (1)while (ADC12CTL1 & ADC12BUSY);//等待转换完成unsigned int result = ADC12MEM0; // 获取转换结果//进一步处理转换结果，如计算实际电压值float voltage = (result / 4096.0) * 2.5;//处理完成后进行下一次转换ADC12CTL0，=ADC12SC;}```以上代码中，首先调用`init_ADC12(`函数进行ADC12模块的初始化配置，然后在主循环中进行转换和结果处理。

MSP430系列的芯片晶振选型报告

1、晶振的基本原理石英晶体，有天然的也有人造的，是一种重要的压电晶体材料。

石英晶体本身并非振荡器，它只有借助于有源激励和无源电抗网络方可产生振荡。

什么是晶振？晶振作用，晶振原理？晶振一般叫做晶体谐振器，是一种机电器件，是用电损耗很小的石英晶体经精密切割磨削并镀上电极焊上引线做成。

这种晶体有一个很重要的特性，如果给他通电，他就会产生机械振荡，反之，如果给他机械力，他又会产生电，这种特性叫机电效应。

他们有一个很重要的特点，其振荡频率与他们的形状，材料，切割方向等密切相关。

由于石英晶体化学性能非常稳定，热膨胀系数非常小，其振荡频率也非常稳定，由于控制几何尺寸可以做到很精密，因此，其谐振频率也很准确。

根据石英晶体的机电效应，我们可以把它等效为一个电磁振荡回路，即谐振回路。

他们的机电效应是机-电-机-电....的不断转换，由电感和电容组成的谐振回路是电场-磁场的不断转换。

在电路中的应用实际上是把它当作一个高Q值的电磁谐振回路。

由于石英晶体的损耗非常小，即Q 值非常高，做振荡器用时，可以产生非常稳定的振荡，作滤波器用，可以获得非常稳定和陡削的带通或带阻曲线。

晶振模块一般需要电源电流为10mA ~60mA。

硅振荡器的电源电流取决于其类型与功能，范围可以从低频（固定）器件的几个微安到可编程器件的几个毫安。

一种低功率的硅振荡器，如MAX7375，工作在4MHz时只需不到2mA的电流。

在特定的应用场合优化时钟源需要综合考虑以下一些因素：精度、成本、功耗以及环境需求。

2、单片机晶振的两个电容的作用这两个电容叫晶振的负载电容，分别接在晶振的两个脚上和对地的电容，一般在几十皮发。

它会影响到晶振的谐振频率和输出幅度，一般订购晶振时候供货方会问你负载电容是多少。

晶振的负载电容=[(Cd*Cg)/(Cd+Cg)]+Cic+△C式中Cd,Cg为分别接在晶振的两个脚上和对地的电容,Cic（集成电路内部电容）+△C（PCB上电容）经验值为3至5pf。

evaluation version of IAR Embedded Workbench withlimitations both in code size and in the service and support that is provided.Limitations:•The C compiler does not generate an assembly code list file.•The code size limit of the MSP430IAR KickStart C/C++Compiler is set to4Kbytes for traditional MSP430devices and8Kbytes for MSP430X devices(see Table2-1for detailed information aboutwhich MSP430device is based on which architecture).•The IAR Assembler delivered is the full version without any restrictions.•The IAR XLINK Linker links a maximum of4Kbytes originating from C source code for traditional MSP430devices and8Kbytes for MSP430X devices(see Table2-1for detailed information aboutwhich MSP430device is based on which architecture),but an unlimited amount of code originatingfrom assembly code.•The IAR KickStart C-SPY Simulator reads a maximum of4Kbytes originating from C code for traditional MSP430devices and8Kbytes for MSP430X devices but is unlimited in the amount ofassembly code read(see Table2-1for detailed information about which MSP430device is based onwhich architecture).•MISRA C is not available.•The runtime library source code is not included.A full(that is,unrestricted)version of the software tools can be purchased from IAR.A mid-featured toolset–called Baseline,with a12Kbyte C-code size limitation and basic floating-point operations–is also available from IAR.See the IAR web site(www.iar.se)for more information.12Development Flow SLAU138AF–June2004–Revised June2014Submit Documentation FeedbackCopyright©2004–2014,Texas Instruments Incorporated Using KickStart 2.2.1Project SettingsThe settings required to configure the Workbench and C-SPY are numerous and detailed.Read andthoroughly understand the documentation supplied by IAR when dealing with project settings.Review the project settings of the supplied assembler and C examples(the project settings are accessed usingProject→Options with the project name selected).Use these project settings as templates whendeveloping your own projects.Note that if the project name is not selected when settings are made,the settings are applied to the selected file(not to the project).The following project settings are recommended or required:•Specify the target device(General Options→Target→Device).•Enable an assembler project or a C or assembler project(General Options→Target→Assembler-only project).•Enable the generation of an executable output file(General Options→Output→Output file→Executable).•To most easily debug a C project,disable optimization[C/C++Compiler→Optimizations→Size→None(Best debug support)].•Enable the generation of debug information in the compiler output(C/C++Compiler→Output→Generate debug information).•Specify the search path for the C preprocessor(C/C++Compiler→Preprocessor→Include Paths).•Enable the generation of debug information in the assembler output(Assembler→Output→Generate Debug Info).•Specify the search path for the assembler preprocessor(Assembler→Preprocessor→Include Paths).•To debug the project using C-SPY,specify a compatible format[Linker→Output→Format→Debug information for C-SPY(with runtime control modules or with I/O emulation modules)].•Specify the search path for any used libraries(Linker→Config→Search paths).•Specify the C-SPY driver.Select Project→Options→Debugger→Setup→Driver→FET Debugger to debug on the FET(that is,MSP430device).Select Simulator to debug on the simulator.If FETDebugger is selected,use Project→Options→FET Debugger→Setup→Connection to select theappropriate port:Texas Instruments LPT-IF for the parallel FET Interface(MSP-FET430PIF)or TexasInstruments USB-IF for the USB Interface(MSP-FET430UIF)or for the eZ430.•Enable the Device Description file.This file makes C-SPY"aware"of the specifics of the device it is debugging.This file corresponds to the specified target device(Debugger→Setup→Devicedescription file→Override default).•Enable the erasure of the Main and Information memories before object code download(FET Debugger→Download→Erase main and Information memory).•To maximize system performance during debug,disable Virtual Breakpoints(FET Debugger→Breakpoints→Use virtual breakpoints)and disable all System Breakpoints(FET Debugger→Breakpoints→System breakpoints on).NOTE:Use Factory Settings to quickly configure a project.Use the Factory Settings button to quickly configure a project to a usable state.The following steps can be used to quickly configure a project.Note that the General Options tab does not have a Factory Settings button.1.Specify the target device(General Options→Target→Device).2.Enable an assembler project or a C or assembler project(General Options→Target→Assembler-only project).3.Enable the generation of an executable output file(General Options→Output→Output file→Executable).4.Accept the factory settings for the compiler(C/C++Compiler→Factory Settings).5.Accept the factory settings for the assembler(Assembler→Factory Settings).13 SLAU138AF–June2004–Revised June2014Development Flow Submit Documentation

Settings).8.Debug on the hardware(Debugger→Setup→Driver→FET Debugger).9.Specify the active parallel port used to interface to the FET if not LPT1(FET Debugger→Setup→Connection→Texas Instruments LPT-IF)or specify the USB port(FET Debugger→Setup→Connection→Texas Instruments USB-IF).NOTE:Avoid the use of absolute path names when referencing files.Instead,use the relative pathname keywords$TOOLKIT_DIR$and$PROJ_DIR$.See theIAR documentation for a description of these keywords.The use of relative path namespermits projects to be moved easily,and projects do not require modification when IARsystems are upgraded(for example,from KickStart or Baseline to Full).2.2.2Using Math Library for MSP430(MSPMathlib)in IAR EW4305.60.1and NewerTI's MSPMathlib is part of EW4305.60.1and newer releases.This optimized library provides up to26x better performance in applications that use floating point scalar math.For details,see the MSPMathlibweb page(/tool/mspmathlib).MSPMathlib may be enabled for new and existing projects on all supported devices.Enable or disable MSPMathlib in the project options(General Options→Library Configuration→MathLib).2.2.3Additional Project Settings for MSP430L092and MSP430C092The MSP430L092can operate in two different modes:L092mode and C092emulation mode.Thepurpose of the C092emulation mode is to behave like a C092with up to1920bytes of code at its final destination for mask generation.The operation mode is determined by EW430before starting the debugger.Two radio buttons areavailable for the mode selection.By default the L092mode is selected(see Figure2-1and Figure2-2).Figure2-1.L092Mode14Development Flow SLAU138AF–June2004–Revised June2014Submit Documentation FeedbackCopyright©2004–2014,Texas Instruments Incorporated Using KickStartFigure2-2.C092Emulation Mode2.2.3.1MSP430L092Loader CodeThe Loader Code in the MSP430L092is a ROM-code from TI that provides a series of services.It enables customers to build autonomous applications without needing to develop a ROM mask.Such an application consists of an MSP430device containing the loader(for example,MSP430L092)and an SPI memorydevice(for example,'95512or'25AA40);these and similar devices are available from variousmanufacturers.The majority of use cases for an application with a loader device and external SPI memory for native0.9-V supply voltage are late development,prototyping,and small series production.Figure2-1shows the selection for loading the application into the external SPI memory.2.2.3.2Password Protection of MSP430C092The MSP430C092is a customer-specific ROM device that is protected by a password.To start a debug session,the password must be provided to EW430.Figure2-3shows how to provide a HEX password in EW430.Figure2-3.C092Password15 SLAU138AF–June2004–Revised June2014Development Flow Submit Documentation FeedbackCopyright©2004–2014,Texas

ultra-low-power mode in which the entry and exit is handled differently than the other low-power modes.LPMx.5gives the lowest power consumption available on a device.To achieve this,entry to LPMx.5disables the LDO of the PMM module,which removes the supply voltage from the core and the JTAGmodule of the device.Because the supply voltage is removed from the core,all register contents andSRAM contents are lost.Exit from LPMx.5causes a BOR event,which forces a complete reset of thesystem.NOTE:The option"RELEASE JTAG ON GO"is currently not supported in the EmbeddedWorkbench when LPMx.5debugging is active.See the MSP430device family user's guidefor additional LPMx.5and ultra-low-power debug mode details.2.2.5.2Enable Ultra-Low-Power Debug ModeTo enable the ultra-low power debug mode feature the“Enable ULP/LPMx.5debug”checkbox must be enabled by clicking FET Debugger->Setup->Enable ULP/LPMx.5debug(see Figure2-4).When the ultra-low power debug mode is enabled a notification is displayed in the Debugger log every time thetarget device enters and leaves LPMx.5mode(see Figure2-5).Press the Halt or Reset button in Embedded Workbench to wake up the target device from LPMx.5.Execution of the code is halted at the start of the program.All breakpoints that had been active beforeLPMx.5are restored and reactivated automatically.Figure2-4.Enable Ultra-Low-Power

† The MSP430F14x1 devices are identical to the MSP430F14x devices with the exception that the ADC12 module is not implemented.
description
The Texas Instruments MSP430 family of ultralow-power microcontrollers consist of several devices featuring different sets of peripherals targeted for various applications. The architecture, combined with five low power modes is optimized to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that attribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 6 µs. The MSP430x13x and the MSP430x14x(1) series are microcontroller configurations with two built-in 16-bit timers, a fast 12-bit A/D converter (not implemented on the MSP430F14x1 devices), one or two universal serial synchronous/asynchronous communication interfaces (USART), and 48 I/O pins. Typical applications include sensor systems that capture analog signals, convert them to digital values, and process and transmit the data to a host system. The timers make the configurations ideal for industrial control applications such as ripple counters, digital motor control, EE-meters, hand-held meters, etc. The hardware multiplier enhances the performance and offers a broad code and hardware-compatible family solution.
