第三讲CST微波工作室的波导性质计算仿真(Lecture CST Microwave Studio simulation calculation waveguide properties)

火龙电子FD51F_DB_V1开发板是刘小良先生的力作，配套程序作为STC15单片机的学习利器，其代码的可读性工整度远超STC工程师的水平，可以作为快速掌握STC15单片机的重要参考(Fire dragon electronic FD51F_DB_V1 development board is Mr Xiao-liang liu s masterpiece, form a complete set of procedures as STC15 microcontroller learning tool, its the readability of the code neat degrees than on STC engineer level, can quickly grasp STC15 single-chip microcomputer as an important reference)

2.4寸 TFT液晶屏在C51单片机上的刷屏测试程序(2.4-inch TFT LCD screen on a single chip in the C51 test procedure Shuabing)

J1939协议栈源码，有详细的使用说明，在KEIL C166 (XC2331D)上编译通过。(J1939 protocol stack source code, compiled on KEIL C166 (XC2331D).)

利用单片机的定时器定时，令十字路口的红绿灯交替点亮和熄灭，实现主支路路口的交通信号灯控制（尽可能保持主线的畅通，即在通常情况下，保持主线的放行，只有在支线到达时，才放行支线），同时采用LED数码管或LCD显示倒计时时间。(The use of single-chip timer timing, make the turn at the crossroads of the traffic lights lit and extinguished achieve the main traffic lights at the junction of the slip control (as much as possible to maintain the smooth flow of the main line, that is, in normal circumstances, to maintain the main line of the release, only at Extension arrive only when the release of the Spur Line), while the use of LED digital tube or LCD display countdown time.)

这是一个基于STC单片机，采用分离原件的125K的ID读卡器全套设计资料，其中包括原理图、PCB以及单片机源程序，还有我做设计时的参考资料。内容很全面的，以及在实物上验证过，可以正常运行。主要使用的天线为820uH。(This is based on STC microcontroller, the separation of the original 125K ID card reader full design information, including schematics, PCB and microcontroller source code, as well as I do the design reference. Content is very comprehensive, and verified on the kind, can operate normally. The main antenna is 820uH.)
