编写0号中断处理程序，使得在除法溢出发生时，在屏幕中间显示字符串“divide error!”，然后返回DOS。(Write 0 interrupt handler, so that when the division overflow occurs in the middle of the screen displays the string divide error! , And then return to DOS.)

燃气轮机热力设计程序。包括低压压气机，高压压气机，燃烧室，高压涡轮，中压涡轮，低压涡轮在内的整个燃气轮机的热力设计。(Gas turbine thermal design process. Including the low-pressure compressor, high pressure compressor, combustor, high pressure turbine, an intermediate pressure turbine and low pressure turbine, including the thermal design of the entire gas turbine.)

基于STM32直接操作寄存器版本，07年开关电源控制程序，采集反馈的电压进行PI调节，达到稳压目的。(Register version based on the STM32 direct operation, 07 switching power supply control procedures, collect feedback PI regulating voltage, voltage regulator.)

说明：  飞思卡尔智能车比赛的C车模的双电机驱动，很好使，尺寸刚好(Freescale smart car race car models dual motor drive C, so good, just the size of)

说明：  STM32入门很好的学习资料，欢迎下载。(STM32 entry is a good learning material, welcome to download)

说明：  设置3个功能键：当某一功能键被按下后，进入相应的功能模式。3个功能有： 1）8路数据采集功能：通过调节可变电阻实现0-5V的电压输出作为8路输入信号使用，每路信号用2位LED显示采集的结果。报警：任意一路超过某一门限（可自己设定）时，发出报警（声音+灯闪烁，并通过灯指示是哪一路报警），同时停止采集。2）计数功能：利用计数功能键，实现每按一次按键，LED显示加1，从0-99计数。3）秒表功能：只用一个键控制。按下一个按键后时钟启动，从零开始计时，计时间隔0.01秒，再按一次后停止。再按一次后清零。如此循环。 本设计采用2个MAX7221串行驱动2个8路数码管显示，更节省单片机I/O口。(AD、count、countdown)

msp430应用笔记 包含msp430手册，以及各项项目开发笔记 PDF 学430必备(MSP430 application notes include MSP430 manual and PDF science 430 necessary notes for various project development)

12864液晶显示，采串并形都有 for msp430 x芯片驱动代码 画图都有十分方便使用 。 12864LCD属于点阵图形液晶显示模块，不但能显示字符，还能显示汉字和图形，分带汉字库和不带那字库两种，价格也有差别。(12864 LCD belongs to dot matrix graphics LCD display module. It can display not only characters, but also Chinese characters and graphics. There are two kinds of Chinese character library and non-Chinese character library, and the price is also different. The 12864LCD with Chinese character library is very convenient to use. It does not need to write complex Chinese character display program. As long as two bytes of Chinese character machine code are written in time sequence, Chinese characters can be displayed. The driver is much simpler.)

rx8025 日历时钟芯片程序，该程序广泛的被移植到实际产品中(rx8025 calendar clock chip program, the program has been ported to a wide range of practical products)

基于AT24C0x和89c52的IIC总线连接与设计及源码(AT24C0x based on the 89C52 and IIC bus connection with the design and source code)
