贴子很好，但需要补充一些材料才能置成酷贴
谢谢你的共享。只是一堆源代码，没有电路图会大幅降低帖子的交流效果。
请将电路图也上传上来，这样本贴就能置COOL，会有更多的人关注，并且能获得本论坛的专家分数(迟些会实施)
你可以编辑本贴上传电路图，或在后面的回复里上传。谢谢对我们网站的支持。
/*这是本人设计的收音机的程序，实际使用效果良好，有时钟，闹钟，红外遥控，频率显示存储功能
用万能板搭的电路，没有画电路图呢，就暂不提供了。关键元件如下：
1602液晶显示屏，TEA5767 FM收音机芯片，ATMEGA16，32768HZ晶振。
CPU时钟1000000HZ
ICCAVR环境编译后占用13K空间，源代码如下：
