本系统分电压测量和信号产生输出两大部分，电压测量部分以模拟电路为主，配合放大模块、A/D转化模块、显示模块；通过凌阳单片机进行数据处理，在误差允许范围内显示测量电压值。信号产生以直接数字式频率合成器为核心，经过AT89S52对DDS芯片内部进行控制，使之输出标准正弦波形，利用编程实现频率预置、步进，达到电压输出频率的可调节步进。通过调试与测量完成了题目的基本部分和全部发挥部分的要求并有自己的创新。-Voltage measurement points of the system and the output of two major signals, voltage measurement circuitry to simulate the main part, with the amplification module, A/D conversion module, display module through Sunplus Single-chip data processing, in the range of error allowed shows the value of measuring voltage. Signal generated by direct digital frequency synthesizer for the core of the DDS chip AT89S52 after the internal control standards so that the output sine wave shape, frequency of use of pre-programming, step to the output voltage adjustable frequency step. Debugging and measurement, through the completion of the basic part of the topic and all the requirements to play a part and have their own innovation.

it is usb based power switch controlled via usb based on avr microcontroller

对FreeRTOS的实现进行了说明，包括TCB调度的实现原理，以及任务通信对象的介绍。

&我的项目是RFID门锁系统。这个系统是用来打开门与RFID传感器。什么时候你要开门，就必须把射频识别卡放到门上接受者ARM控制器读取卡中的数据，检查卡中的代码，比较eeprom中的用户代码和卡中的代码是否正确是的，门会为这个人打开的。
