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。
（3）
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
TEA5757采用了一种所谓的自动调谐系统，在自动搜索时无须读中频，简化了程序。-digital radio attention to the election : (1) remote control chip with TC9012/TC9243 launch frequently used were UPD6121 and LC 7461, the only different is that the lead time for different code or data of the number of different spaces, accept the basic tenets of the same.
