基于AVR单片机的挖掘机器人控制系统设计( Based on AVR monolithic integrated circuit s excavation robot control system design )

PIC12C5X系列单片机应用手册，详细介绍了，硬件结构，软件开发，应用实例等(PIC12C5X Series Singlechip manuals and detailed introduction, the hardware structure, software development, application examples, etc.)

又一种抢答器的AT89S51程序， SW1 SW2 SW3 SW4 用数码管显示最先按下的按键 01 02 03 04 并点亮对应灯： D2 D3 D4 D5 显示2S后退出。 同时发出 “嘟”一声。(Yet another answering device AT89S51 procedures, SW1 SW2 SW3 SW4 with digital display by pressing the button the first 01 02 03 04 and light the corresponding lamp: D2 D3 D4 D5 Display 2S exit. Also issued a " beep" sound.)

这里说明了键盘中alt的用途，希望大家喜欢，对大家有用哈.....(it is a very useful DOC)

单片机4x4键盘程序，好用！！！！！！！！！！！！！！！！！！(dd)

说明：  使用Jk触发器实现PLL鉴频器电路 还没仿真测试 只作为参考(jk flipflop for PLL frequency discriminator)

RN8209D计量芯片参考电路详细,SCH文件、PCB文件、EMC设计参考(RN8209D measurement chip reference circuit in detail, SCH documents, PCB files, EMC design reference)

pn532开发的单片机源代码，作为开发NFC的试验用,可读写ISO14443-A/B协议的射频卡和felica以及宝石卡(pn532 developed microcontroller source code, as the development of NFC test, can read and write ISO14443-A/B protocol and RF cards and jewel card felica)

说明：  基于stm32f103的多路ADC采集，将采集的电压传入到DMA设定的内存中，在通过均值滤波得到比较准确的数据(Based on the multi-channel ADC acquisition of stm32f103, the collected voltage is transferred to the memory set by DMA, and the more accurate data are obtained by means of mean filter.)
