用于单片机的开发 用modbus协议 实现上位机与下位机的通讯

用c语言串口接受数据的功能 在单片机中很实用！-C language accepted by serial single-chip data at a very practical!

C51强大功能及其高效率的重要体现之一在于其丰富的可直接调用的库函数，多使用库函数使程序代码简单，结构清晰，易于调试和维护，下面介绍C51的库函数系统。-C51 powerful features and its high efficiency in one important manifestation of its rich can directly call the library, multi-use library functions to make the code simple, clear and easy to debug and maintenance, and C51 introduced below the library system.

LED的电路连接方法，多年经验。有很多种方法可供选择，很重要，希望大家能去持我。-circuit OF led.thank you .It s my own performation,hope you give me a great help.

汽车遥控制的源代码.用的单片机是PIC16F72. 大批量生产.-Car remote control s source code. Singlechip is used PIC16F72. High-volume production.

单片机和温度传感器的应用，错误很多。可作为无线应用的基础。请踊跃下载啊。

利用AT89C51单片机做的一个音乐卡,可以播放多首歌曲-AT89C51 single-chip microcomputer use to do a music card, can play more songs

利用51单片机控制ISD2560语音芯片实现语音的录放和存储，可自动调用，很实用的程序，绝对原创！-51 SCM control the use of voice chip ISD2560 voice playback and storage, can automatically call a very useful procedure, an absolute original!

用于arm开发，keil开发环境-arm for the development, Keil development environment

555编程器，用于单片机编程使用，可以用一用就知道有没有！-555 programmer, programming for the use of SCM can be used on a not know!

用两块51单片机基于RS232实现单片机之间的串行通信。又从机检测到当地温度，然后由主机查询，从从机读得温度数据。该程序时C51程序。-MCU with 2 RS232-based serial communication between the SCM. And from machine to detect the local temperature, and then by the host queries, from the temperature data from the machine-readable too. The program C51 program.
