基于vc6环境下开发,实现了打开文件操作,利用了fltk图形开发包,(Based on the vc6 environment, the open file operation is realized, and the fltk graphics development kit is used.)

功能描述：这是一个示波器波形显示控件，能够完成类似于示波器的功能。最多可以同时显示8个通道的数据波形，可以动态切换显示通道。缩放xy轴，弹出半透明窗口显示坐标，y轴方向平移波形等功能。 操作使用键盘快捷键，操作说明见readme.txt，目前按键焦点的得到有点问题，要点击开始后在示波器上鼠标左键单击一下，然后按一下上箭头键，才可以响应按键指令，有高手知道怎么改进希望告诉作者：xiang57@163.com(Functional Description: This is an oscilloscope waveform display control, able to complete similar oscilloscope function. At the same time show up to eight channels of waveform data can be displayed dynamically switch channels. Zoom xy axis, translucent pop-up window displays the coordinates, y-axis direction of translational wave functions. Operation of the use of keyboard shortcuts, operating instructions see readme.txt, the current key focus has been a problem, it is necessary to click on the oscilloscope after the beginning click the left mouse button, and then click on the arrow keys, before they can respond to key commands, has a master know how to tell the authors hope to improve: xiang57@163.com)

基于51单片机的电子钟设计。这个可以对于普通的51单片机，可以实现时间的计时，还可以设置闹钟，还有秒表功能，整点报时。(Electronic clock design based on 51 single chip microcomputer.This can be for the ordinary 51 microcontroller, can achieve the timing of time, but also can set the alarm clock, there are stopwatch function, the hour.)

用于在SDT环境下实现交叉环境中代码写入FLASH的过程，已测试(SDT for the environment to achieve cross-code into the environment FLASH process, have tested)
