基于Cy7y168013USB接口芯片的逻辑分析仪keil源码(Logic analyzer based on Cy7y168013USB interface chip keil source code)

南京罗姆显示器 单片机显示控制软件，显示 频率码和标识信息。(Single chip microcomputer display control software, display frequency code and identification information in Nanjing.)

基于FRDM-KL25Z及简单运放（LM324）设计出了一套小巧、低成本的心电监测装置。它不但能够结合上位机实时显示心电图而且能够将采集的心电信号储存于SD卡，用于24h心电监护，以备观察不同时间段心血管疾病的症状。(FRDM-KL25Z and simple operational amplifier (LM324) based on the designed ECG monitoring device with a set of small, low cost. It can not only combine with the real-time display of the host computer and can store the collected ECG signals in SD card for 24h ECG monitoring for the observation of the symptoms of cardiovascular diseases at different time periods. )

SIM800C升级工具,二次开发工具，省成本的特别好用用的方案(SIM800C upgrade tool)

A program to consicle very mad and good !! yes :

1000以内所有的完数，比较简单，用于学习和交流(1000 all finished within few, relatively simple, for learning and communication)

说明：  内有电路图和对应的程序，已经调试成功，能实现定时功能。(There are circuit diagrams and the corresponding procedures are debugging success, to achieve timing.)

AVR,JTAG仿真软件，内涵源程序和电路图，直接烧写进单片机就可以在线仿真的(AVR, the simulation software of JTAG, content of the source code and circuit diagram, directly burned into the microcontroller can online simulation )

基于单片机STC89C51和74LS164的多功能数字万用表(Based on microcontroller STC89C51 and 74 ls164 multi-function digital multimeter)

说明：  定时器的使用，让你了解使用定时器所必须的几个步骤！从而能够使用(the use of timers let you know by the use of timers to be a few steps! In order to use)
