NXP Semiconductor designed the LPC2400 microcontrollers around a 16-bit/32-bitARM7TDMI-S CPU core with real-time debug interfaces that include both JTAG andembedded Trace. The LPC2400 microcontrollers have 512 kB of on-chip high-speedFlash memory. This Flash memory includes a special 128-bit wide memory interface andaccelerator architecture that enables the CPU to execute sequential instructions fromFlash memory at the maximum 72 MHz system clock rate. This feature is available onlyon the LPC2000 ARM Microcontroller family of products. The LPC2400 can execute both32-bit ARM and 16-bit Thumb instructions. Support for the two Instruction Sets meansEngineers can choose to optimize their application for either performance or code size atthe sub-routine level. When the core executes instructions in Thumb state it can reducecode size by more than 30 % with only a small loss in performance while executinginstructions in ARM state maximizes core performance.

单片机入门知识手册 说到单片机，首先想到的是中央处理器（CPU），学过微型计算机的人都知道，CPU是计算机最核心的部分，它可以完成算术运算和逻辑运算，CPU再配上外部存储器，输入输出单元就构成一台微型计算机。其实单片机可以看成一台微型计算机，它具有CPU的功能，并且自身带有存储器，带有输入输出接口（如串行UART、AD转化、PWM控制），单片机配上一些简单的外围电路，就可以完成智能控制或数据采集等。所以，单片机的英文名叫MCU（Micro chip Uint），翻译成中文是微控制单元。 单片机能干什么？通俗一点讲，单片机只有两个功能：一个是数据采集，另一个是控制。其实都很好理解，数据采集实际上是从外间输入，如从AD（模数转化）口读入一个电压值，从串口接收一个数据等等。控制实际上是输出，51单片机有32个IO口，每个IO口可以驱高或驱低，单片机以此来实现对外间的控制。一个单片机系统都可以用下面这个框图来说明：

The CAT28LV64 is a low voltage, low power, CMOS Parallel EEPROM organized as 8K x 8−bits. It requires a simple interface for in−system programming. On−chip address and data latches, self−timed write cycle with auto−clear and VCC power up/down write protection eliminate additional timing and protection hardware. DATA Polling and Toggle status bit signal the start and end of the self−timed write cycle. Additionally, the CAT28LV64 features hardware and software write protection.

This application report discusses the design of non-invasive optical plethysmographyalso called as pulsoximeter using the MSP430FG437 Microcontroller (MCU). Thepulsoximeter consists of a peripheral probe combined with the MCU displaying theoxygen saturation and pulse rate on a LCD glass. The same sensor is used for bothheart-rate detection and pulsoximetering in this application. The probe is placed on aperipheral point of the body such as a finger tip, ear lobe or the nose. The probeincludes two light emitting diodes (LEDs), one in the visible red spectrum (660nm) andthe other in the infrared spectrum (940nm). The percentage of oxygen in the body isworked by measuring the intensity from each frequency of light after it transmitsthrough the body and then calculating the ratio between these two intensities.

以典型的9S08 系列为例，当你选择了一个MCU 型号后，在图1-4 右侧会显示出所有针对该型号芯片可用的项目调试场景。其中：Full chip Simulator”是芯片全功能模拟仿真，即无需任何目标系统的硬件资源，直接在你的PC 机上模拟运行单片机的程序，在模拟运行过程中可以观察调试程序的各项控制和运行流程，分析代码运行的时间，观察各种变量，等等。CW 提供了功能强大的模拟激励功能，可以在模拟运行时模拟一些外部事件的输入，配合程序调试；P&E Multilink/Cyclone Pro”是基于P&E 公司的硬件调试工具实现实时在线硬件调试。实际就是我们经常说的BDM 调试。BDM 调试是基于芯片本身内含的在线调试功能，可实现程序下载，单步／全速运行，可以设若干个断点，可以观察和修改任意寄存器或RAM 内存空间。BDM 几乎是开发飞思卡尔8 位（9S08 和RS08 系列）、16 位（9S12 系列）和32 位（Coldfire V1 系列）单片机的标准调试模式，运用最为广泛；SofTec HCS08”是另外一家SofTec 公司提供的硬件调试工具，国内使用较少；HCS08 Serial Monitor”是基于芯片串口的监控调试开发模式。由于开发效率较低，现在几乎无人使用。
