msp430各功能模块的介绍

各个时钟信号源介绍如下：1、LFXT1CLK：低频/高频时钟源。

可以外接32768Hz的时钟芯片或频率为450KHz~8MHz的标准警惕或共振器。

2、XT2CLK:高频时钟源。

需要外接两个震荡电容器。

可以外接32768Hz的时钟芯片或频率为450KHz~8MHz的标准警惕或共振器和外部时钟输入。

较常用的晶体是8MHz的。

3、DCOCLK：内部数字可控制的RC振荡器。

MSP430单片机时钟模块提供3个时钟信号以供给片内各部分电路使用，这3个时钟信号分别是：（1）ACLK：辅助时钟信号。

ACLK是从LFXT1CLK信号由1/2/4/8分频器分频后得到的。

由BCSCTL1寄存器设置DIV A相应位来决定分频因子。

ACLK可提供给CPU外围功能模块做时钟信号使用。

（2）MCLK:主时钟信号。

MCLK是由3个时钟源所提供的。

它们分别是：LFXT1CLK、XT2CLK、和DCO时钟源信号。

MCLK主要用于MCU和相关模块做时钟。

同样可设置相关寄存器来决定分频因子及相关设置。

（3）SMCLK：子系统时钟。

SMCLK由2个时钟源信号提供，他们分别是XT2CLK 和DCO。

如果是F11或F11X1系列单片机，则由LFXT1CLK代替XT2CLK。

同样可设置相关寄存器来决定分频因子及相关的设置。

低频振荡器LFXT1:LFXT1支持超低功耗，它在低频模式下使用一个32768Hz的晶体。

不需要任何电容因为在低频模式下内部集成了电容。

低频振荡器也支持高频模式和高速晶体，但连接时每端必须加电容。

电容的大小根据所接晶体频率的高低来选择。

低频振荡器在低频和高频模式下都可以选择从XIN引脚接入一个外部输入时钟信号，但所接频率必须根据所设定的工作模式来选择，并且OSCOFF位必须复位。

高频振荡器LFXT2：LFXT2作为MSP430的第二晶体振荡器。

与低频相比，其功耗更大。

高频晶体真大气外接在XIN2和XOUT2两个引脚，并且必须外接电容。

All operations, other than program-flow instructions,are performed as register operations in conjunc-tion with seven addressing modes for source operand and four addressing modes for destina-tion operand.The CPU is integrated with 16 registers that provide reduced instruction execution time. The register-to-register operation execution time is one cycle of the CPU clock.Four of the registers, R0 to R3, are dedicated as program counter, stack pointer, status register,and constant generator respectively. The remain-ing 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 51 instructions with three formats and seven address modes. Each instruction can operate on word and byte data.Table 1 shows examples of the three types of instruction formats; the address modes are listed in Table 2.Table 1. Instruction Word FormatsTable 2. Address Mode Descriptionsoperating modesThe MSP430 has one active mode and five software selectable low-power modes of 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 mode 0 (LPM0);–CPU is disabledACLK and SMCLK remain active. MCLK is disabledD Low-power mode 1 (LPM1);–CPU is disabledACLK and SMCLK remain active. MCLK is disabledDCO’s dc-generator is disabled if DCO not used in active modeD Low-power mode 2 (LPM2);–CPU is disabledMCLK and SMCLK are disabledDCO’s dc-generator remains enabledACLK remains activeD Low-power mode 3 (LPM3);–CPU is disabledMCLK and SMCLK are disabledDCO’s dc-generator is disabledACLK remains activeD Low-power mode 4 (LPM4);–CPU is disabledACLK is disabledMCLK and SMCLK are disabledDCO’s dc-generator is disabledCrystal oscillator is stoppedinterrupt vector addressesThe interrupt vectors and the power-up starting address are located in the address range 0FFFFh – 0FFE0h.The vector contains the 16-bit address of the appropriate interrupt-handler instruction sequence.2.Interrupt flags are located in the module.3.Nonmaskable: neither the individual nor the general interrupt-enable bit will disable an interrupt event.4.(Non)maskable: the individual interrupt-enable bit can disable an interrupt event, but the general-interrupt enable can not disableit.5.Timer_B7 in MSP430x14x family has 7 CCRs; Timer_B3 in MSP430x13x family has 3 CCRs. In Timer_B3 there are only interruptflags TBCCR0, 1, and 2 CCIFGs and the interrupt-enable bits TBCCTL0, 1, and 2 CCIEs.special function registersMost interrupt and module-enable bits are collected in the lowest address space.

Access to the MSP430 memory via the BSL is protected by user-defined password. For complete description of the features of the BSL and its implementation, see the Application report Features of the MSP430Bootstrap Loader , Literature Number SLAA089.flash memoryThe 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 two segments of information memory (A and B) of 128bytes each. Each segment in main memory is 512 bytes in size.D Segments 0 to n may be erased in one step, or each segment may be individually erased.D Segments A and B can be erased individually, or as a group with segments 0–n.Segments A and B are also called information memory.D New devices may have some bytes programmed in the information memory (needed for test duringmanufacturing). The user should perform an erase of the information memory prior to the first use.Main MemoryInformation Memory8 kB 0FFFFh 0FE00h 0FDFFh 0FC00h 0FBFFh 0FA00h 0F9FFh16 kB 0FFFFh 0FE00h 0FDFFh 0FC00h 0FBFFh 0FA00h 0F9FFh32 kB 0FFFFh 0FE00h 0FDFFh 0FC00h 0FBFFh 0FA00h 0F9FFh48 kB 0FFFFh 0FE00h 0FDFFh 0FC00h 0FBFFh 0FA00h 0F9FFh60 kB 0FFFFh 0FE00h 0FDFFh 0FC00h 0FBFFh 0FA00h 0F9FFh0E400h 0E3FFh 0E200h 0E1FFh 0E000h 010FFh 01080h 0107Fh 01000h0C400h 0C3FFh 0C200h 0C1FFh 0C000h 010FFh 01080h 0107Fh 01000h08400h 083FFh 08200h 081FFh 08000h 010FFh 01080h 0107Fh 01000h04400h 043FFh 04200h 041FFh 04000h 010FFh 01080h 0107Fh 01000h01400h 013FFh01200h 011FFh01100h 010FFh01080h 0107Fh01000hperipheralsPeripherals are connected to the CPU through data, address, and control busses and can be handled using all instructions.digital I/OThere are six 8-bit I/O ports implemented—ports P1 through P6: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 P1 and P2.D Read/write access to port-control registers is supported by all instructions.oscillator and system clockThe clock system in the MSP430x13x and MSP43x14x family of devices is supported by the basic clock module that includes support for a 32768-Hz watch crystal oscillator, an internal digitally-controlled oscillator (DCO) anda high frequency crystal oscillator. The basic clock module is designed to meet the requirements of both lowsystem cost and low-power consumption. The internal DCO provides a fast turn-on clock source and stabilizes in less than 6 µs. The basic clock module provides the following clock signals:D Auxiliary clock (ACLK), sourced from a 32768-Hz watch crystal or a high frequency crystal.D Main clock (MCLK), the system clock used by the CPU.D Sub-Main clock (SMCLK), the sub-system clock used by the peripheral modules.watchdog timerThe primary function of the watchdog timer (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.multiplication (MSP430x14x Only)The multiplication operation is supported by a dedicated peripheral module. The module performs 1616, 168, 816, and 88 bit operations. The module is capable of supporting signed and unsigned multiplication as well as signed and unsigned multiply and accumulate operations. The result of an operation can be accessed immediately after the operands have been loaded into the peripheral registers. No additional clock cycles are required.USART0The MSP430x13x and the MSP430x14x have one hardware universal synchronous/asynchronous receive transmit (USART0) peripheral module that is used for serial data communication. The USART supports synchronous SPI (3 or 4 pin) and asynchronous UART communication protocols, using double-buffered transmit and receive channels.USART1 (MSP430x14x Only)The MSP430x14x has a second hardware universal synchronous/asynchronous receive transmit (USART1) peripheral module that is used for serial data communication. The USART supports synchronous SPI (3 or 4 pin) and asynchronous UART communication protocols, using double-buffered transmit and receive channels.Operation of USART1 is identical to USART0.timer_A3Timer_A3 is a 16-bit timer/counter with three capture/compare registers. Timer_A3 can support multiple capture/compares, PWM outputs, and interval timing. Timer_A3 also has extensive interrupt capabilities.Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare registers.timer_B7 (MSP430x14x Only)Timer_B7 is a 16-bit timer/counter with seven capture/compare registers. Timer_B7 can support multiple capture/compares, PWM outputs, and interval timing. Timer_B7 also has extensive interrupt capabilities.Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare registers.timer_B3 (MSP430x13x Only)Timer_B3 is a 16-bit timer/counter with three capture/compare registers. Timer_B3 can support multiple capture/compares, PWM outputs, and interval timing. Timer_B3 also has extensive interrupt capabilities.Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare registers.comparator_AThe primary function of the comparator_A module is to support precision slope analog–to–digital conversions, battery–voltage supervision, and monitoring of external analog signals.ADC12The ADC12 module supports fast, 12-bit analog-to-digital conversions. The module implements a 12-bit SAR core, sample select control, reference generator and a 16 word conversion-and-control buffer. The conversion-and-control buffer allows up to 16 independent ADC samples to be converted and stored without any CPU intervention.peripheral file mapperipheral file map (continued)peripheral file map (continued)peripheral file map (continued)absolute maximum ratings over operating free-air temperature (unless otherwise noted)†. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Voltage applied at V CC to V SS–0.3 V to + 4.1 V. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Voltage applied to any pin (referenced to V SS) –0.3 V to V CC+0.3 V. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Diode current at any device terminal . ±2 mA. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Storage temperature (unprogrammed device) –55°C to 150°C. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Storage temperature (programmed device) –40°C to 85°C †Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.

用户可直接在我们的DEMO板上实现一个完整的单相多功能电能表。

1 板面布局如图1-1，电表的板面说明如下：1、时段指示灯：D101,D102,D1032、有功脉冲指示：LED4013、有功脉冲输出口：J4034、无功脉冲指示：LED4025、无功脉冲输出口：J4026、 38K载波红外接收头：B3007、红外发射器：B3018、 485通信接口：RS4859、 FE42X内部电能计量模块电流通道I1输入回路接口：J40010、 FE42X内部电能计量模块电流通道I2输入回路接口：J40111、 FE42X内部电能计量模块电压通道V1输入回路接口：J200我们知道FE42X的内置计量模块ESP具有两个电流通道，可同时测量火线和零线电流实现防窃电电表。

在DEMO中我们需要短接电流通道I2，如图1-1。

由于电流通道I2回路接口在外部短接，所以电流通道I1RMS始终大于电流通道I2RMS，因此在DEMO程序中，我们不再关心两个通道的电流大小，始终以电流通道I1作为计算依据。

当然，只要你喜欢，你完全可以把电流通道I2的短接去掉，利用两个电流通道实现防窃电电表。

这里有一点需要注意，我们在两个电流通道上都添加了CT的负载电阻，电流通道I1(R400)，电流通道I2(R401)。

MSP430单片机原理解读

第 2 章MSP430 单片机原理与 C 语言基础MSP430系列超低功耗单片机有200多种型号，TI公司用3~ 4位数字表示其型号。

其中第一位数字表示大系列，如MSP430F1xx系列、MSP430F2xx系列、MSP430F4xx系列、MSP430F5xx系列等。

在每个大系列中，又分若干子系列，单片机型号中的第二位数字表示子系列号，一般子系列越大，所包含的功能模块越多。

最后1~2 位数字表示存储容量，数字越大表示RAM 和ROM 容量越大。

430 家族中还有针对热门应用而设计的一系列专用单片机。

如SP430FW4xx 系列水表专用单片机、MSP430FG4xx 系列医疗仪器专用单片机、MSP430FE4xx 系列电能计量专用单片机等。

这些专用单片机都是在同型号的通用单片机上增加专用模块而构成的。

最新的MSP430型号列表可以通过TI公司网站下载。

在开发单片机应用系统时，第一步就是单片机的选型，选择合适的单片机型号往往就能事半功倍。

单片机选型基本方法是选择功能模块最接近项目需求的系列，然后根据程序复杂程度估算存储器和RAM 空间，并留有适当的余量，最终决定选用的单片机型号。

msp430 百科介绍

MSP430MSP430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位超低功耗的混合信号处理器(Mixed Signal Processor)。

称之为混合信号处理器，主要是由于其针对实际应用需求，把许多模拟电路、数字电路和微处理器集成在一个芯片上，以提供“单片”解决方案。

1、MSP430 单片机的发展MSP430 系列是一个16 位的、具有精简指令集的、超低功耗的混合型单片机，在1996 年问世，由于它具有极低的功耗、丰富的片内外设和方便灵活的开发手段，已成为众多单片机系列中一颗耀眼的新星。

回忆MSP430 系列单片机的发展过程，可以看出有这样三个阶段：开始阶段从1996 年推出MSP430 系列开始到2000 年初，这个阶段首先推出有33X 、32X 、31X 等几个系列，而后于2000 年初又推出了11X 、11X1 系列。

MSP430 的33X 、32X 、31X 等系列具有LCD 驱动模块，对提高系统的集成度较有利。

每一系列有ROM 型（ C ）、OTP 型（P）、和EPROM 型（ E ）等芯片。

EPROM 型的价格昂贵，运行环境温度范围窄，主要用于样机开发。

这也表明了这几个系列的开发模式，即：用户可以用EPROM 型开发样机；用OTP型进行小批量生产；而ROM 型适应大批量生产的产品。

2000 年推出了11X/11X1 系列。

这个系列采用20 脚封装，内存容量、片上功能和I/O 引脚数比较少，但是价格比较低廉。

这个时期的MSP430 已经显露出了它的特低功耗等的一系列技术特点，但也有不尽如人意之处。

它的许多重要特性，如：片内串行通信接口、硬件乘法器、足够的I/O 引脚等，只有33X 系列才具备。

33X 系列价格较高，比较适合于较为复杂的应用系统。

当用户设计需要更多考虑成本时，33X 并不一定是最适合的。

而片内高精度A/D 转换器又只有32X 系列才有。

寻找突破，引入Flash技术随着Flash 技术的迅速发展，TI 公司也将这一技术引入MSP430 系列中。

前言
温度控制是科研和实际生产中经常用到的一类控制系统，为保障生产的安全进行，提高产品的质量和数量，降低工人的劳动强度，节省人力、节约能源等，常常要实现温度的自动控制。然而，要实现高精度的温度自动控制就必须采用计算机控制系统，它可以实现温度信号的采集、显示及控制等，并可用计算机软件实现升温、降温和闭环自动控制。
DS 18B20 测温模块采用单总线数字温度传感器 DS18B20 测量温度，直接输出数节省硬件电路。且该芯片的物理字信号。便于单片机处理及控制，化学性很稳定，此元件线形性能好， 0～100 ℃时，在最大线形偏差小于 1 ℃。DS18B20 的最大特点之一是采用了单总线的数据传输，它直接输出温度的数字信号到微控制器。每只 DS18B20 具有一个独有的不可修改的 64 位序列号，根据序列号可访问不同的器件。这样一条总线上可以挂接多个 DS18B20 传感器，实现多点温度测量，轻松的组建传感网络。 DS18B20 温度传感器是美国 DALLAS 半导体公司最新推出体积小、使用方的一种改进型智能温度传感器，具有耐磨耐碰性、便、封装形式多样，与传统的热敏电阻等测温元件相比，它能直接读出被测温度，并且可根据实际要求通过简单的编程实现 9～12 位的数字值读数方式。 3.3 音频模块 ISD1420 为美国 ISD 公司出品的优质单片语音录放电路，由语音存储单元、前置放大器、自动增益控制电路、抗干扰滤振荡器、波器、输出放大器组成。一个最小的录放系统仅由 1 个麦克风、 1 个喇叭、个按钮、个电源、 2 1 少数电阻电容组成。录音内容存入永久存储单元，提供零功率信息存储，这个独一无二的方法是借助于美国 ISD 公司的专利—— —直接模拟存储技术（DAST TM 实现的。）利用它，语音和音频信号被直接存储，以其原本的模拟形式进入 EEPROM 存储器，直接模拟存储允许使用一种单片固体电路方法完成其原本语音的再现，仅语音质量优胜，而且断电语音保护。 3.4 时钟模块 DS1302 是美国 DALLAS 公司推出的具有涓细电流充电能力的低功耗实时时钟电路。主要特点是采用串行数据传输，可为掉电保护电源提供可编程的充电功能，并且可以关闭充电功能。采用普通 32.768 kHz 晶振。电路的主要功能是向单片机提供时间的信息，包括年、日、月、星期及具体的时、秒值等信息。可编程芯片分、 DS1302 内部有寄存器及 RAM，通过编程可由单片机完成对 DS1302 内部的时钟／日历提供的秒、时及年、日、分、月、星期等信息进行读出，并可根据需要进行修改。 3.5 按键设计该系统中用到 8 个按键的功能分别是： SW1 设定时间； SW2 设定温度上下限用； SW3 确认； SW4 实时播报时间、温度； SW5 加 l； SW6 减 l； SW7 切换屏幕显示； SW8 保留扩展。P0 的 8 个 I／O 口接 8 个独立式按键即可满足需要。按下其中一个按键，则可由单片机准确判断，去执行相应的程序。 3.6 显示模块采用 RT1602 两行 16 个字符的显示，能同时显示日期、时间、星期、温度。采用液晶显示器件，可使显示平稳、省电、美观，对后续的功能兼容性高，只需将软件作修改即可，（下转第 136 页） 3.2
