Description: 数字选台收音机
注意:
(1)遥控发射芯片用TC9012/TC9243
经常用到的还有UPD6121和LC7461,它们的不同只处在于引导码的时间不同或者数据位的个数不同,接受原理基本一样。将本程序的相关位置修改就可以通用。
系统时钟22.1184MHZ,如果用其他的时钟请将delay.c文件中的定时器装载值修改一下
(2)
键盘检测在VFD程序中,16312可以驱动VFD,另外外部可接24个按键,并将按键值放到
其内部的存储中,使用时只须发命令读即可。

由于时间原因,只给出调幅波段的自动搜台功能,调频的自动搜台程序和调幅一样,自己写了。
(4)主要用在组合机和功放机上的收音头大部分以LC72171做锁象环,LA1823做高中频处理
和音频解调,但是有的数调收音头把锁象环和高频处理做在一起,典型的有TEA5757和TEA5756

Description: 随着人们的生活水平的日益提高,洗衣机的使用也越来越普及,目前全国的洗衣机的年产量已超过1000万台。洗衣机的分类较多,根据不同的角度大致可分如下几类:
洗衣机从不同洗衣的原理来说可分为波轮洗衣机、滚筒洗衣机、以及搅拌式洗衣机。
洗衣机从结构上又可分为:单缸和双缸洗衣机;
洗衣机从水流方式上又可分为:瀑布水流、手搓水流、悬浮水流等;
洗衣机从电机的驱动方式上又可分为:间接驱动和直接驱动(DD型洗衣机);
从洗衣机的电机的驱动电源的不同可分为:普通洗衣机和变频洗衣机,其中变频洗衣机又可分为:直流变频洗衣机和交流变频洗衣机;
从洗衣机的显示方式来分有:LED灯显示、数码管显示、LCD显示、以及VFD显示。
目前在国内波轮洗衣机占洗衣机用量的大部分,滚筒洗衣机和搅拌式洗衣机在国内很少,主要在欧美的家庭大量使用。但近几年滚筒洗衣机洗衣机在国内的市场呈快速增长。
-with people's standard of living and increasing the use of washing machines have become increasingly popular, At present, the annual production of washing machines has more than 10 million Taiwan. Classification more washing machines, according to different perspectives can be largely classified into the following categories : Laundry washing machines from different example of the principle can be divided into Wave Wheel washing machines, drum washing machines, washing machines and stirring. Washing machines from the structure can be divided into : single cylinder and double cylinder washing machine; Washing machines from the current mode can be divided into : a waterfall flowing hand molded flow, suspended flow; from the washing machine motor-driven approach can be divided into : Indi
