The bootloader is stored in the internal boot ROM memory (system memory) of STM32devices. It is programmed by ST during production. Its main task is to download theapplication program to the internal Flash memory through one of the available serialperipherals (USART, CAN, USB, etc.). A communication protocol is defined for each serialinterface, with a compatible command set and sequences

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.

PICKIT™ 2 PROGRAMMER-TO-GO USER GUIDE The PICkit 2 Programmer-To-Go functionality allows a PIC MCU memory image to be downloaded into the PICkit 2 unit for later programming into a specific PIC MCU. No software or PC is required to program devices once the PICkit 2 unit is set up for Programming-To-Go. A USB power source for the PICkit 2 is all that is needed.

Keil C51使用詳解Keil C51 是美國Keil Software 公司出品的51 系列兼容單片機C 語言軟件開發系統，與匯編相比，C 語言在功能上、結構性、可讀性、可維護性上有明顯的優勢，因而易學易用。用過匯編語言后再使用C 來開發，體會更加深刻。Keil C51 軟件提供豐富的庫函數和功能強大的集成開發調試工具，全Windows界面。另外重要的一點，只要看一下編譯后生成的匯編代碼，就能體會到Keil C51生成的目標代碼效率非常之高，多數語句生成的匯編代碼很緊湊，容易理解。在開發大型軟件時更能體現高級語言的優勢。下面詳細介紹 Keil C51 開發系統各部分功能和使用。第二節 Keil C51 單片機軟件開發系統的整體結構C51 工具包的整體結構，如圖(1)所示，其中uVision 與Ishell 分別是C51 forWindows 和for Dos 的集成開發環境(IDE)，可以完成編輯、編譯、連接、調試、仿真等整個開發流程。開發人員可用IDE 本身或其它編輯器編輯C 或匯編源文件。然后分別由C51 及A51 編譯器編譯生成目標文件(.OBJ)。目標文件可由LIB51 創建生成庫文件，也可以與庫文件一起經L51 連接定位生成絕對目標文件(.ABS)。ABS 文件由OH51 轉換成標準的Hex 文件，以供調試器dScope51 或tScope51 使用進行源代碼級調試，也可由仿真器使用直接對目標板進行調試，也可以直接寫入程序存貯器如EPROM 中。圖(1) C51 工具包整體結構圖第三節 Keil C51 工具包的安裝81. C51 for Dos在 Windows 下直接運行軟件包中DOS\C51DOS.exe 然后選擇安裝目錄即可。完畢后欲使系統正常工作須進行以下操作(設C:\C51 為安裝目錄)：修改 Autoexec.bat，加入path=C:\C51\BinSet C51LIB=C:\C51\LIBSet C51INC=C:\C51\INC然后運行Autoexec.bat2. C51 for Windows 的安裝及注意事項：在 Windows 下運行軟件包中WIN\Setup.exe，最好選擇安裝目錄與C51 for Dos相同，這樣設置最簡單(設安裝于C:\C51 目錄下)。然后將軟件包中crack 目錄中的文件拷入C:\C51\Bin 目錄下。第四節 Keil C51 工具包各部分功能及使用簡介1. C51 與A51(1) C51C51 是C 語言編譯器，其使用方法為：C51 sourcefile[編譯控制指令]或者 C51 @ commandfile其中 sourcefile 為C 源文件(.C)。大量的編譯控制指令完成C51 編譯器的全部功能。包控C51 輸出文件C.LST，.OBJ，.I 和.SRC 文件的控制。源文件(.C)的控制等，詳見第五部分的具體介紹。而 Commandfile 為一個連接控制文件其內容包括：.C 源文件及各編譯控制指令，它沒有固定的名字，開發人員可根據自己的習慣指定，它適于用控制指令較多的場合。(2) A51A51 是匯編語言編譯器，使用方法為：9A51 sourcefile[編譯控制指令]或 A51 @ commandfile其中sourcefile 為匯編源文件(.asm或.a51)，而編譯控制指令的使用與其它匯編如ASM語言類似，可參考其他匯編語言材料。Commandfile 同C51 中的Commandfile 類似，它使A51 使用和修改方便。2. L51 和BL51(1) L51L51 是Keil C51 軟件包提供的連接/定位器，其功能是將編譯生成的OBJ 文件與庫文件連接定位生成絕對目標文件(.ABS)，其使用方法為：L51 目標文件列表[庫文件列表] [to outputfile] [連接控制指令]或 L51 @Commandfile源程序的多個模塊分別經 C51 與A51 編譯后生成多個OBJ 文件，連接時，這些文件全列于目標文件列表中，作為輸入文件，如果還需與庫文件(.LiB)相連接，則庫文件也必須列在其后。outputfile 為輸文件名，缺少時為第一模塊名，后綴為.ABS。連接控制指令提供了連接定位時的所有控制功能。Commandfile 為連接控制文件，其具體內容是包括了目標文件列表，庫文件列表及輸出文件、連接控制命令，以取代第一種繁瑣的格式，由于目標模塊庫文件大多不止1 個，因而第2 種方法較多見，這個文件名字也可由使用者隨意指定。(2) Bl51BL51 也是C51 軟件包的連接/定位器，其具有L51 的所有功能，此外它還具有以下3 點特別之處：a. 可以連接定位大于64kBytes 的程序。b. 具有代碼域及域切換功能(CodeBanking & Bank Switching)c. 可用于RTX51 操作系統RTX51 是一個實時多任務操作系統，它改變了傳統的編程模式，甚至不必用main( )函數，單片機系統軟件向RTOS 發展是一種趨勢，這種趨勢對于186 和38610及68K 系列CPU 更為明顯和必須，對8051 因CPU 較為簡單，程序結構等都不太復雜，RTX51 作用顯得不太突出，其專業版軟件PK51 軟件包甚至不包括RTX51Full，而只有一個RTX51TINY 版本的RTOS。RTX51 TINY 適用于無外部RAM 的單片機系統，因而可用面很窄，在本文中不作介紹。Bank switching 技術因使用很少也不作介紹。3. DScope51，Tscope51 及Monitor51(1) dScope51dScope51 是一個源級調試器和模擬器，它可以調試由C51 編譯器、A51 匯編器、PL/M-51 編譯器及ASM－51 匯編器產生的程序。它不需目標板（for windows 也可通過mon51 接目標板），只能進行軟件模擬，但其功能強大，可模擬CPU 及其外圍器件，如內部串口，外部I/O 及定時器等，能對嵌入式軟件功能進行有效測試。
