很完整的门禁系统原码，希望能帮助大家更好的学习学习一下...

本人以前做的一个DVD+TV 项目，51用做控制，含 NEC红外遥控接收和转发，VFD1632驱动，OSD 芯片M35055，NTSC高频头控制以及I2C 24C02的读写，因为以前所写，有些地方看起来有点乱，但功能模块OK，整个程序也是可以运行的，希望能给初用者有点参考-I used to do a TV DVD, 51 used as a control, with NEC infrared remote control and forwarding, VFD1632 drive, OSD M35055 chip, NTSC tuner control and I2C 24C02 read and write, because it was written in some places appear to be a little messy, but functional modules OK, the entire procedure can be run in hopes of giving users a bit early reference
