公司擁有優(yōu)秀的銷(xiāo)售團(tuán)隊(duì)和專(zhuān)業(yè)的研發(fā)部門(mén)，不但在品牌、價(jià)格、供貨、服務(wù)等方面領(lǐng)先業(yè)界，而且可為客戶提供及時(shí)、可行的技術(shù)支持和整體設(shè)計(jì)服務(wù)，滿足不同客戶多層次需求。
網(wǎng)絡(luò)收音機(jī)(iRadio)應(yīng)用簡(jiǎn)介
網(wǎng)絡(luò)收音機(jī)(iRadio)是我們合作伙伴RnD的一個(gè)案例，他使用了一顆低端的MCU來(lái)處理音頻解碼，用W5100來(lái)處理網(wǎng)絡(luò)網(wǎng)絡(luò)音頻流數(shù)據(jù)的接受。主芯片是ATMEL AVR32, 服務(wù)器采用了DLNA公開(kāi)服務(wù)器程序。
最終實(shí)現(xiàn)了音頻流的網(wǎng)絡(luò)播放功能。
其示意圖和主要配置如下。
主要硬件配置：
Hardware Specifications:
- AVR32 for MP3 and WMA decoding
- W5100 10/100Mbps Ethernet Controller with Network Protocols
- 1MByte SDRAM for audio buffering
- 2.4” color TFT (320x240)
- DC 5V input for core, DC12 input for Audio Amplifier
BOM List:
- W5100 + RJ45
- AVR32 or similar
- SDRAM 1MByte
- 2.4” TFT (2.2”)
- Power and Misc
- Audio Amplifier (about 20W)
Features:
- Local playback on SD Card (pending, waiting for Atmel)
- Internet Radio with MP3 (working now) and WMA format (debugging)
- Download Station lists from Portal in XML format
- DLNA Renderer to play audio streamed from DLNA server
- Server format:
? HTTP: working now
? MMS: implementing
? RTSP: planned
Applications:
- Internet Radio, with DLNA Renderer
- Embedded with other AV system, (no need to count TFT), such as Boom box, Photo frame, DVB, DVD…
even we could share the SoC in the system, for example, in DVD; we just need to add W5100 + RJ45 to have same functions.
