TCP/IP Networking: Internet Radio Using OLED Display and MP3 Audio Decoder
Howard Schlunder, Rodger Richey
The focus of this application note is to show how to create a low-cost Internet Radio that connects to SHOUTcast servers and plays MP3 audio. The hardware uses the PIC18F67J60 microcontroller with integrated 10Base-T MAC and PHY and an external MP3 audio decoder. The software uses the standard Microchip TCP/IP Stack with external serial SRAM buffering to ease the streaming of compressed audio data to the MP3 decoder. Figure 1 shows a picture of the Internet Radio Demonstration Board (DM183033) that is available for purchase on MicrochipDirect or through one of Microchip?s distributors. Figure 2 shows the block diagram for the Internet Radio design used in this application note.
