介紹了一種基于MSP430系列單片機(jī)和ADXL203加速度傳感器的數(shù)字式傾角儀，它不僅可以實(shí)現(xiàn)水平度檢測(cè)，而且可以測(cè)量00～3600范圍內(nèi)的任意傾角，分辨率可達(dá)O．1。。此外，由于該傾角儀輸出為數(shù)字結(jié)果，因此它也可以與其他的數(shù)字設(shè)備結(jié)合起來，組合成一個(gè)功能更加強(qiáng)大的儀器。該數(shù)字傾角儀可廣泛應(yīng)用于建筑、機(jī)械、道路、橋梁、石油、煤礦和地質(zhì)勘探等各種需要測(cè)量重力參考系下傾角的場(chǎng)合。關(guān)鍵詞：MSP430F133單片機(jī)；力敏傳感器；ADXL203加速度計(jì)；角度測(cè)量 Abstract：This paper presents a new style digital inclinometer which is developed on the basis of the MSP430F133 MCU and the ADXL203 dual axis aeeelerometer．This inclinometer not only can test levelness，but also can measure any angle between 0。and 360。with an accuracy of 0．1 O．In addition，its output is a digital result，which makes it possible to integrate itself with other digital devices to form a more functional unit．This inclinometer can be widely used in any construction site，oil field，coal-mine or geologic survey and SO on where it will provide the working people with convenience to measure any angles．Key words：MSP430F133 MCU；force sensor；ADXL203 accelerometer；angle measurement

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.

IntroductionAs chip designers pack more functions into ICs,pin counts continue to grow and the space betweenpins keeps shrinking. Pin spacings of 0.5 mm and0.65 mm are not at all uncommon. The power ofthese new ICs is wonderful, to be sure, but trou-bleshooting them can be a chore because connect-ing scopes and logic analyzers has become muchmore difficult and less dependable.

Keil C251設(shè)計(jì)軟件V3.11(4k代碼限制） keil c251 v3.11 demo版的安裝說明：安裝方法是先將V3.11安裝程序用winzip解壓縮到某個(gè)目錄下。（不要直接點(diǎn)擊setup.exe安裝），比如解壓縮到c:\c251然后執(zhí)行c:\c251\setup\setup.exe 安裝程序，這個(gè)程序會(huì)讓你選擇安裝Eval Version版還是Full Version版，選擇Eval Version版進(jìn)行安裝 安裝好之后就可以使用，但有代碼大小的限制。需要無限制的版本，請(qǐng)購買正版軟件。 C251是intel公司的16位單片機(jī)，指令兼容51的單片機(jī)。8位單片機(jī)風(fēng)靡了20年，下一個(gè)20年應(yīng)該是16位單片機(jī)的世界。
