Designing Boards with Atmel AT89C51,AT89C52, AT89C1051, and AT89C2051 for Writing Flash at In-Circuit Test. Recent improvements in chips and testers have made it possible for the tester to begin taking over the role tradi-tionally assigned to the PROM program-mer. Instead of having a PROM pro- grammer write nonvolatile memories before assembling the board, the in-cir- cuit tester writes them during in-circuit testing operations. Many Teradyne Z18- series testers are now in use loading code into nonvolatile memories, micro- controllers and in-circuit programmable logic devices. The purpose of this note is to explain how the Z18 approaches the writing task for Atmel AT89C series IC’s, so that designers of boards using these chips can get the best results.

The MSP-FET430PIF is a Parallel Port interface (does not include target board) that is used to program and debug MSP430 FET tools and test boards through the JTAG interface. This interface is included in our FET tools, but sold without the development board. This interface uses a Parallel PC Port to communicate to the Debugger Software (IAR Kickstart software included) running on the PC. The interface uses the standard 14 pin header to communicate to the MSP430 device using the standard JTAG protocol. The flash memory can be erased and programmed in seconds with only a few keystrokes, and since the MSP430 flash is extremely low power, no external power supply is required. The tool has an integrated software environment and connects directly to the PC which greatly simplifies the set-up and use of the tool. The flash development tool supports development with all MSP430 flash parts. Features MSP430 debugging interface to connect a MSP430-Flash-device to a Parallel port on a PC Supports JTAG debug protocol (NO support for Spy-Bi-Wire (2-wire JTAG) debug protocol, Spy-Bi-Wire (2-wire JTAG) is supported by MSP-FET430UIF) Parallel Port cable and a 14-conductor target cable Full documentation on CD ROM Integrated IAR Kickstart user interface which includes: Assembler Linker Limulator Source-level debugger Limited C-compiler Technical specifications: Backwardly compatable with existing FET tool boards.

The MSP-FET430U14 is a powerful flash emulation tool to quickly begin application development on the MSP430 MCU. It includes USB debugging interface used to program and debug the MSP430 in-system through the JTAG interface or the pin saving Spy Bi-Wire (2-wire JTAG) protocol. The flash memory can be erased and programmed in seconds with only a few keystrokes, and since the MSP430 flash is ultra-low power, no external power supply is required. The debugging tool interfaces the MSP430 to the included integrated software environment and includes code to start your design immediately. The MSP-FET430UIF development tools supports development with all MSP430 flash devices

CCAVR软件有ISP功能，能过调用STK500完成的，只要设置好参数，在ICCAVR中就可以给芯片编程了，还可以让程序一编译完就自动下载到芯片中，相当方便。在Tools->environment options->ISP里设定STK500.exe的路径。— 用于调用STK500程序。在Tools->In system programming 里Programmer Interface中选中STK500。— 选择STK500下载方式。在Tools->In system programming 里把Auto Program After Compile 的小勾选上。— 编译后自动编程。在Tools->In system programming 中还有一些设置项，大家可以根据需要进行相关设置。下面的图片是操作过程。

ICCAVR简介ICCAVR 是一种使用ANSI 标准C 语言来开发微控制器（MCU）程序的一个工具，它是一个综合了编辑器和工程管理器的集成工作环境（IDE）。源文件全部被组织到工程之中，文件的编辑和工程（project）的构筑也在IDE 的环境中完成。编译错误在状态窗口中显示，用鼠标单击编译错误时，光标会自动跳转到出错行。这个工程管理器还能直接产生INTEL HEX格式的烧写文件和可以在AVR Studio 中调试的COFF 格式的调试文件。这里特别要提一下ICCAVR 中的应用构筑向导，可以在Tools 栏中选择“ApplicationBiulder”或者直接点击快捷工具栏中的“Application Biulder”图标，就可以打开应用构筑向导对话框，可以根据需要设定芯片种类，各个端口初始值，是否使用定时器，中断，UART等，选好以后单击“OK”就可以得到所需的硬件初始化程序段，非常可靠而且方便。图1给出了初始化UART 的一个例子：下面介绍一下创建并编译一个工程文件的简要步骤：1．新建一个源文件从file 菜单中选择new，创建一个新文件，在改文件中输入源程序并进行编辑和修改，然后存盘，在存盘时必须指定文件类型，如命名为：try.c 。写一个新文件的步骤：首先用Biulder 初始化需要用到的硬件资源，生成初始化程序，然后再写需要的代码实现所要的功能。2．新建一个project从projrct 菜单中选择new 命令，IDE 会弹出一个对话框，在对话框中用户可以指定工程存放的文件夹和工程的名称。在建立一个新工程之后，在工程管理器的窗口会出现三个子目录，Files, Headers, Documents,这时就可以将要编译的文件添加到project 中了。3．把文件添加到工程中可以在project-files 里单击右键，选择需要添加的文件；也可以在编辑窗口中单击右键选择弹出窗口的“Add To Project”命令。4．编译源文件在编译之前特别要注意在Project Options 中选择与硬件相应的芯片。如本次实验就选择ATMEGA8515,如图2 所示。在project 中选择make project,也可以直接单击快捷键F9，这时要是有错则会弹出出错信息，修改调试正确以后单击快捷键ISP 就可以烧写到硬件中去了。

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。
