vb中的DataGrid网格控件用法演示，相信很多人都很喜欢使用DataGrid来配合数据库显示内容吧，确实是很基储很直观的一个数据库控件，几乎很多的VB数据库程序中，都可以看到它的身影。这个例子比较简单，但可以让你掌握DataGrid的用法。

电子时钟，可以显示四位，两位显示分钟，两位显示秒，可以用按键控制清零，以及加减数(Electronic clock, you can display four bit, two bit display minutes, the second display seconds, can be used to control the key to clear, and the addition of subtraction)

用ＰＩＣ１６Ｆ５１０单片机，实现按键调光程序。按键按一下为强光，按两下为工作光，工作光电流为强光的１／２，按３下为频闪，按４下为关机。且程序设定低电压报警功能，当外部供电不足９.９Ｖ时会闪烁１０次，低于８.４Ｖ时关机

说明：  常见有限差分格式构造，并有fortran代码实现，适合cfd学习(Common finite difference format construction, and FORTRAN code implementation, suitable for CFD learning)

experiment equipment: stm32F103 C8T6 Purpose: ADC real-time sampling shows waveforms through an anonymous host computer (virtual oscilloscope) ADC1 and serial 1 dual DMA use to speed up the transfer rate Hardware resources: 1, ADC1 channel 1 (peripheral A1) 2, serial port 1 (baud rate: 500000) Experimental phenomena: The anonymous host computer displays the waveform in real time. The sampling frequency of the ADC is about 1Mhz (the highest value of the single ADC mode has been reached, but the maximum transmission rate of the host computer is about 500000 baud. And only one byte per transfer of 14 bytes is valid (caused by the anonymous transfer protocol). It takes about 2.8ms to transfer once.

基于unittest的测试用例代码，仅供参考(Unittest-based test case code,for reference only)

此程序的功能是，采用细胞自动机方法，进你火灾模拟。(This program' s function is, using cellular automata method, into your fire simulation.)

用VB编写的2DCS小游戏，适合新手学习(2DCS, written by VB, is suitable for novice)
