LPC2119MiniBoardPCB

Three phase AC-DC-AC converter which has the PWM controller technique within that

直流无刷电机分类、驱动模型建立、PID模糊控制理论(Classification of Brushless DC motor, establishment of driving model and PID fuzzy control theory)

三合一模块,Mc20的硬件设计手册，已经通过做项目(Triad module, Mc20 hardware design manual, already by doing projects )

说明：  底层使用，你懂的,主要用于运行特定通讯程序的底层调用功能(You will kown how use it.)

利用51单片机完成16*16 点阵led屏的字符显示(16*16 led display)

类似电脑键盘组合按键触发的功能。利用51单片机实现。有两个独立按键，当把两个独立按键都按下后，蜂鸣器发出“滴”的一声后就停。直到松开任一个按键后，才能重新进行下一次的组合按键触发。(Similar to the function of the keyboard combination of keys. The use of 51 single chip microcomputer. There are two independent buttons, when the two independent buttons are pressed, the buzzer issued a drop of sound after the stop. Until after the release of any key, the next combination of keys can be re trigger. )

说明：  ntp客户端连接， 嵌入式C， 通过ntp服务器同步并更新本地时间，同步，计算，修改 ntp客户端连接， 嵌入式C， 通过ntp服务器同步并更新本地时间，同步，计算，修改(syncronize with time server. syncronize with time server.)

基于C语言的GSM模块sim808的51驱动程序(The 51 driver of the GSM module sim808)

说明：  led闪烁简单的c51入门程序代码，适合初学者入门的程序代码(LED flashes a simple entry procedures C51 code Suitable for beginners entry code )
