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)

TG19264（点阵式无字库192*64）LED驱动，可在任列和行显示，可反白显示.-TG19264 (dot-matrix font free 192* 64) LED driver can be in any column and row shows that can be highlighted.

Small RTOS 移植到AVR下用IAR编译的-Small RTOS ported to AVR using the IAR compiler

单片机音乐程序的设计与实验，包含音乐程序的设计原理。-music SCM procedures and experimental design, including music program design principles.

PWM波程序 可以用来控制电机调速，程序比较简单，这里只用了一个定时器就实现了。因为51单片机没有PWM波的寄存器，所以要自己用软件控制。-PWM waves program can be used to control motor speed, procedure is simple, here only a timer is realized. Because no PWM waves 51-series microcomputer to yourself, so with registers control software.

帮朋友写的一个用MCS-51的IO口模拟PWM使外接LED亮度渐变的程序，虽然程序小，不过注释清楚，并已调试OK。-written for a friend with a MCS-51 simulation of the IO mouth so that external PWM LED brightness gradual process Although procedures for small, but clearly Notes, and debugging OK.

c8052的I2C子程序,比较实用可靠,我们使用的是C8051F020-c8052 I2C subroutine, more practical and reliable, we are using the C8051F020
