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

数字钟是一种用数字电路技术实现时、分、秒计时的装置，与机械式时钟相比具有更高的准确性和直观性，且无机械装置，具有更更长的使用寿命，因此得到了广泛的使用。数字钟从原理上讲是一种典型的数字电路，其中包括了组合逻辑电路和时序电路。目前，数字钟的功能越来越强，并且有多种专门的大规模集成电路可供选择-Digital Clock is a digital circuit technology with the hours, minutes, seconds, timing devices, as compared with the mechanical clock has a higher accuracy and intuitive, and no mechanical devices, with more longer life, so be a wide range of use. Digital clock from the principle of speaking, is a typical digital circuits, including combinational logic circuits and sequential circuits. At present, the digital clock and more powerful, and there are a variety of specialized large scale integrated circuits to choose from
