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軟件有ISP功能，能過調(diào)用STK500完成的，只要設置好參數(shù)，在ICCAVR中就可以給芯片編程了，還可以讓程序一編譯完就自動下載到芯片中，相當方便。在Tools->environment options->ISP里設定STK500.exe的路徑?！?用于調(diào)用STK500程序。在Tools->In system programming 里Programmer Interface中選中STK500?！?選擇STK500下載方式。在Tools->In system programming 里把Auto Program After Compile 的小勾選上?！?編譯后自動編程。在Tools->In system programming 中還有一些設置項，大家可以根據(jù)需要進行相關設置。下面的圖片是操作過程。

ICCAVR簡介ICCAVR 是一種使用ANSI 標準C 語言來開發(fā)微控制器（MCU）程序的一個工具，它是一個綜合了編輯器和工程管理器的集成工作環(huán)境（IDE）。源文件全部被組織到工程之中，文件的編輯和工程（project）的構筑也在IDE 的環(huán)境中完成。編譯錯誤在狀態(tài)窗口中顯示，用鼠標單擊編譯錯誤時，光標會自動跳轉到出錯行。這個工程管理器還能直接產(chǎn)生INTEL HEX格式的燒寫文件和可以在AVR Studio 中調(diào)試的COFF 格式的調(diào)試文件。這里特別要提一下ICCAVR 中的應用構筑向導，可以在Tools 欄中選擇“ApplicationBiulder”或者直接點擊快捷工具欄中的“Application Biulder”圖標，就可以打開應用構筑向導對話框，可以根據(jù)需要設定芯片種類，各個端口初始值，是否使用定時器，中斷，UART等，選好以后單擊“OK”就可以得到所需的硬件初始化程序段，非?？煽慷曳奖?。圖1給出了初始化UART 的一個例子：下面介紹一下創(chuàng)建并編譯一個工程文件的簡要步驟：1．新建一個源文件從file 菜單中選擇new，創(chuàng)建一個新文件，在改文件中輸入源程序并進行編輯和修改，然后存盤，在存盤時必須指定文件類型，如命名為：try.c 。寫一個新文件的步驟：首先用Biulder 初始化需要用到的硬件資源，生成初始化程序，然后再寫需要的代碼實現(xiàn)所要的功能。2．新建一個project從projrct 菜單中選擇new 命令，IDE 會彈出一個對話框，在對話框中用戶可以指定工程存放的文件夾和工程的名稱。在建立一個新工程之后，在工程管理器的窗口會出現(xiàn)三個子目錄，F(xiàn)iles, Headers, Documents,這時就可以將要編譯的文件添加到project 中了。3．把文件添加到工程中可以在project-files 里單擊右鍵，選擇需要添加的文件；也可以在編輯窗口中單擊右鍵選擇彈出窗口的“Add To Project”命令。4．編譯源文件在編譯之前特別要注意在Project Options 中選擇與硬件相應的芯片。如本次實驗就選擇ATMEGA8515,如圖2 所示。在project 中選擇make project,也可以直接單擊快捷鍵F9，這時要是有錯則會彈出出錯信息，修改調(diào)試正確以后單擊快捷鍵ISP 就可以燒寫到硬件中去了。

以典型的9S08 系列為例，當你選擇了一個MCU 型號后，在圖1-4 右側會顯示出所有針對該型號芯片可用的項目調(diào)試場景。其中：Full Chip Simulator”是芯片全功能模擬仿真，即無需任何目標系統(tǒng)的硬件資源，直接在你的PC 機上模擬運行單片機的程序，在模擬運行過程中可以觀察調(diào)試程序的各項控制和運行流程，分析代碼運行的時間，觀察各種變量，等等。CW 提供了功能強大的模擬激勵功能，可以在模擬運行時模擬一些外部事件的輸入，配合程序調(diào)試；P&E Multilink/Cyclone Pro”是基于P&E 公司的硬件調(diào)試工具實現(xiàn)實時在線硬件調(diào)試。實際就是我們經(jīng)常說的BDM 調(diào)試。BDM 調(diào)試是基于芯片本身內(nèi)含的在線調(diào)試功能，可實現(xiàn)程序下載，單步／全速運行，可以設若干個斷點，可以觀察和修改任意寄存器或RAM 內(nèi)存空間。BDM 幾乎是開發(fā)飛思卡爾8 位（9S08 和RS08 系列）、16 位（9S12 系列）和32 位（Coldfire V1 系列）單片機的標準調(diào)試模式，運用最為廣泛；SofTec HCS08”是另外一家SofTec 公司提供的硬件調(diào)試工具，國內(nèi)使用較少；HCS08 Serial Monitor”是基于芯片串口的監(jiān)控調(diào)試開發(fā)模式。由于開發(fā)效率較低，現(xiàn)在幾乎無人使用。
