基于单片机的电子称实验 希望大家能够喜欢 用的是51系列单片机(Microcontroller-based electronics experiments hope you will enjoy with the 51 series)

NPN silicon planar epitaxial transistor encapsulated in a SOT223 surface mounted envelope and designed primarily for use in hand-held radio equipment in the 470 MHz communications band.

使用DataAdapter对数据库进行操作 将SQL-search.aspx程序可改为使用DataAdapter对数据库进行操作. 程序使用"Dim objAdapt As New OleDbDataAdapter(strcmd,objCon)"创建了DataAdapter对象。(Use DataAdapter to operate the database The SQL-search.aspx program can be changed using the DataAdapter to operate the database. The program uses "Dim objAdapt As New OleDbDataAdapter (strcmd, objCon)" Creating a DataAdapter object. )

GPS导航系统 c语言 51单片机开发(in-vehicle GPS navigation system)

Msp430 LaunchPad s sound code that edited by Visual C++l.

crc校验的一种计算方式，可以用于网络协议或串口、can协议的校验位计算，有封装好的函数(A calculation crc check can be used for network protocols or serial port, can protocol parity bit calculation, there is a good function package)

基于51系列单片机的eeprom例程，其中包括c,hex及其相关文件，硬件电路图，相关芯片介绍。(Based on 51 series MCU eeprom routines, including c, hex and its associated files, hardware schematics, related chip introduced.)

能够非常完美的在LED上显示漂亮的汉字和英文字母，很好啊(Can be perfectly nice in the LED display of Chinese characters and English letters, ah well)

串口与pc机通讯，51单片机例程，只需要修改io口即可实现。(Serial communication with pc, 51 MCU routine, you only need to modify the io port can be realized.)

用于计算同步电机发生三相短路故障时，功角随时间的变化关系。(For the calculation of the three-phase short circuit fault occurs synchronous motors, power angle changes with time.)
