| 摘 要： | 采用nRF24Z1无线射频芯片对电视机顶盒的数字音频S/PDIF信号进行无线发送与接收。该方案根据实际应用环境设计电路,并采用PIC18系列单片机分别对发送端和接收端射频芯片及接收端的D/A转换芯片进行配置,并设计按键控制其音量的增减。实验表明,该方案能够实时接收机顶盒音频,且在室内收听时音质较好。

| Abstract: | The design uses a radio frequency chip nRF24Z1 to achieve wireless sending and receiving signals of TV set-top boxes＇s digital audio S/PDIF.Based on the actual application environment,the program designs circuit and uses the family of PIC18 microcontroller to configure the sending and receiving RF chip and receiving end D/A chip,and designs buttons to control the volume change.The experiment shows that the program can receive real-time set-top box audio and the sound quality in the room is clear. |
