斜度测试程序 * 程序对应的硬件设置为：利而达MSP430-Test44x实验板，斜度计使用的 * 是ADXL202E，数字y连接TA1/P1.2,数据x连接P1.0/TA0,P4.6对应斜度计电源 * 每个方向的斜度显示时都占用三个字符， * 斜度范围为0~90,高于90的，斜度为(180－斜度）-Gradient procedures for the corresponding test procedures* for the hardware set up: Lee MSP430-Test44x of the board, of the use of gradient is the* ADXL202E, the number of y connecting TA1/P1.2, data x connect P1.0/TA0, P4. gradient of 6 corresponds to the power* of the gradient in each direction are occupied by shows that the three characters,* angle range of 0 ~ 90, more than 90, and slope for the (180- angle)

该头文件配合key.c，在main函数中调用key.c，都文件中添加key.h，使软件更清晰，一目了然-The header file with key.c, in the main function call key.c, all files add key.h, so that software is more clear at a glance

这是CRC校验源码的分析，让你更了解CRC校验的原理-This is the CRC-source analysis and let you know more about the principles of the CRC

程序详细功能介绍： * 利用AT89S51单片机的P0端口的P0.0－P0.7连接到一个共阳数码管的a－h的笔段上， * 数码管的公共端通过三极管8550选通。在数码管上循环显示0－9数字，显示时间的间隔可通过修改延时程序。 -Procedures detailed functional Introduction:* use AT89S51 MCU port P0 is connected to P0.0-P0.7 Yang a total digital control of the a-h T segment,* digital tube through the public side-gated transistor 8550. In the digital control on the circulation figures 0-9 show, indicating the time interval may be delayed by modifying the procedures.
