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).)

建立环状队列保存过去10个键盘状态，利用天然获得的时延，消键抖，防止连续动作，选择响应模式（下键或抬键动作）。还可以防止两键同按引起的误动作，这里主要靠键值识别，两键同下的键值与单键下键的值不同，拒绝之即可。(Create circular queue holds the state over the past 10 steps of the keyboard, using natural available delay, jitter elimination keys, to prevent the continuous action, select the response mode (the key or lift button action). You can also prevent the two key malfunction caused by the same, this is mainly identified by the key, two keys with one-touch keys with the following value under the key difference, the refusal can be.)

AT89C2051时钟程序，有注释，开心学习！(AT89C2051Clockprocess)

单片机模拟交通灯显示。其中，红灯与绿灯显示时间均为50s，中间的黄灯显示时间为15s。绿灯用八位发光二极管流动闪烁作代表；红灯用八位发光二极管全亮作代表；黄灯用八位发光二极管全亮全灭闪烁作代表。刚开始显示的为绿灯。(SCM simulated traffic light display. Among them, the red and green display times are 50s, in the middle of the yellow light is displayed for 15s. Green with eight light-emitting diode flashes as a representative flow red with eight full brightness light-emitting diodes as a representative yellow with eight light-emitting diodes for all light flashes Quanmie representatives. Just beginning to show as green. Display order: green- yellow- red- yellow- green- yellow- red- ..................)

经典赛车游戏的基础模型，基于LPC2138芯片设计，可在ILI9320 LCD触摸屏上操作(The basis of classic car racing game model, based on the LPC2138 chip design, can be in ILI9320 LCD touch screen operation)

变压器（Transformer）是利用电磁感应的原理来改变交流电压的装置，主要构件是初级线圈、次级线圈和铁芯（磁芯）。主要功能有：电压变换、电流变换、阻抗变换、隔离、稳压（磁饱和变压器）等。按用途可以分为：电力变压器和特殊变压器（电炉变、整流变、工频试验变压器、调压器、矿用变、音频变压器、中频变压器、高频变压器、冲击变压器、仪用变压器、电子变压器、电抗器、互感器等）。电路符号常用T当作编号的开头.例: T01, T201等。(A transformer (Transformer) is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (core). The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) and so on. It can be divided into power transformers and special transformers (electric transformer, rectifier and transformer, power frequency transformer, voltage regulator, mine change, audio transformer, intermediate frequency transformer, high-frequency transformer, shock transformer, transformer, transformer, reactor, intersenser, etc.). Circuit symbols usually use T as the beginning of numbering. Examples: T01, T201 and so on.)
