调频收音机的软硬件设计

Design of Software and Hardware for FM Radio

阐述独立设计功能电路,以STC12LE5204AD单片机为控制核心,配合74HC4511、CH340G、QN8035的不同功能芯片,实现功能模块电路,在实现指定频段接收的同时,配置了外接耳机播放功能、按键控制功能、频段显示功能。测试表明,此设计运行稳定,调节功能灵敏,整体功能流畅可靠。

This paper describes the independent design of functional circuit,which uses STC12LE5204AD single chip microcomputer as the control core,and cooperates with different functional chips of 74HC4511,CH340G,and QN8035 to realize the functional module circuit.While realizing the reception of the specified frequency band,it also configures the external headset playing function,key control function,and frequency band display function.The test shows that the design runs stably,the adjustment function is sensitive,and the overall function is smooth and reliable.
