多路舵机控制

基于AT89C51单片机的出租车计价器的程序设计(AT89C51 microcontroller Taximeter-based program design)

加速度传感器很好用的，，可以移植的，你可以学习下，写的也不容易呢(Using an acceleration sensor,, you can refer to him,, a good, satisfying transplant)

该工具可以根据输入的UNICODE十六进制字符串计算出相应的汉字或ASCII码。比如：输入4F60便可以得到"你"。(The tool can be based on the input UNICODE calculate the corresponding hexadecimal string guy or ASCII.)

实现用单片机控制直流电机调速功能，可用，有hex文件(Achieve MCU control DC motor speed control function is available, a hex file)

时钟芯片DS1302的MSP430的驱动程序，模块化书写，很好调用！(DS1302 clock chip MSP430 drivers, modular writing, good call!)

读写器与射频卡通信的设计采用RC522射频读写芯片与射频卡进行通信，符合ISO14443规范协议；硬件系统设计中主要有AVR单片机主控模块、电源模块、存储模块、外部时钟模块、LCD模块；软件系统设计采用C语言，遵循模块化和结构化编程模式，设计了射频卡操作程序、软关机与自动关机程序、LCD显示、串行Flash存储器、外部时钟等外部设备驱动程序。所设计的手持式读写器具备对MF1 S50、S70射频卡的读写、实时状态显示、系统在线升级以及关机等功能。(This handset can process the data offline or online, reading and writing from 10 cm far. This handset is low-power, miniature, modular design and so on. This article includes: the communication design between RF card and Reader, hardware system design and software systems design. The communication design between RF card and Reader used to RC522 RF chip control RF cards, in line with ISO14443 standard protocol Hardware system design mainly include AVR microcontroller control modules, power modules, memory modules, external clock modules, LCD modules Software system designed with C programming language, and follow the modular structure of the programming model, and has the RF card operation procedures, soft shutdown and automatic shutdown procedures, LCD display, serial Flash memory, an external clock, and other external device driver Procedures. The handset readers has the MF1 S50, S70 RF card reader function, real-time status display function, the system online update function and so)

基于STM32的双串口通信程序，能实现两个串口的收发，程序默认采用串口2接收数据，串口1发送(Based on the STM32 dual serial communication procedures, can achieve two serial transceivers, the program defaults to the serial port 2 receives the data, send the serial port 1)

在STM32F4平台上移植的ucos-ii和ucgui,很适合正在学习ucos-ii和ucgui的朋友(On STM32F4 porting ucos-ii and ucgui, very suitable for studying ucos-ii and ucgui friend)

宽频放大器,有以下功能: 预置增益,增益加/减,显示输出电压有效值,自动增益 显示有效值. 增益输入及加减 自动增益没有实现(Wideband amplifier has the following functions: Preset gain, gain plus/minus, the display output voltage RMS, automatic gain display rms. AGC gain input and subtraction is not implemented)

本程序是虚拟示波器，可以显示多条曲线波形，调节幅值和时间(Oscilloscope can display multiple curve )
