mifare rc500 读卡器源码

Proteus仿真实例，单片机学习的好帮手-Proteus simulation, single-chip learning a good helper

本科毕业设计做的一个东西,用的是AT908515,驱动128*64的LCD,开发环境是ICCAVR6.22.这些代码现在已经在成熟的产品中应用了-Undergraduate Graduation do something, using the AT908515. Drivers 128* 64 LCD, ICCAVR6.22 development environment. these codes are now in a mature application of the product

用单片机产生pwm波形的程序，可以在proteus 下进行仿真-Pwm waveforms generated with the microcontroller program can be carried out under the proteus simulation

密码锁m128 avr-Locks m128 avr

dmx512通讯程序,可以接收dmx512格式的数据-dmx512 communication procedures, can receive the data format dmx512

此代码是运用KEILC51语言编写的关于高低频率测量的高效代码,具有极大的实用性.-use of this code is KEILC51 language on the level of frequency measurement efficient code, great practicality.

该代码是在单片机MCU中实现多线程的嵌入式操作系统-the code is in SCM MCU achieve multithreading RTOS

本代码是本人毕设所做的GPRS数传系统的软件部分，实现了PPP，UDP，IP协议的分层和打包，实现了嵌入式设计中的UDP/IP协议栈-the code is completed, I set up the GPRS data-transmission system software, to achieve the PPP, UDP, IP protocol layering and packaged to achieve the design of embedded UDP/IP protocol stack

51单片机程序，请大家试一下，请多提宝贵意见-51 SCM procedures, please try everyone, please mention the valuable advice

51系列单片机的IIC软件包，模拟通信软件包，可以和具有IIC的芯片使用-51 Series MCU IIC package, analog communications package, you can chip and the use of IIC
