Description: 功能如下
使用STM32F103ZE芯片，通过DM9000AEP把互联网上的网络音频流（支持shoutcast、http mp3流）抓取下来，先在板子上外扩的SRAM上缓存。然后在STM32F103ZE上通过mp3软件解码器解码变成PCM音频，通过DMA方式送到PCM1770进行回放；
它也可以流畅播放SD卡上的mp3、wav格式文件。（支持大于4G的SD卡）；
通过3.2寸240*320的TFT触摸屏、五向按键、红外遥控器进行控制；
红外遥控器具备自学习功能；
系统信息显示；
LCD背光、音量可调，触摸灵敏度可随时校准；(Functions are as follows
The use of STM32F103ZE chip, through the DM9000AEP to the Internet network audio stream (Shoutcast, HTTP MP3) to crawl down, the cache in the outer SRAM expansion board. Then, on STM32F103ZE, the MP3 software decoder decodes it into PCM audio and sends it to the PCM1770 for playback via DMA;
It also allows you to play MP3 and WAV files on the SD card smoothly. (support SD card larger than 4G);
Through the 3.2 inch 240*320 TFT touch screen, five button, infrared remote control;
Infrared remote controller has self-learning function;
System information display;
LCD backlight, adjustable volume, touch sensitivity can be adjusted at any time;) Platform: |

Description: This is my second 5.1 remote kit project. I have included four sections in this project. First one is a pre-amp, the second one is a controller, the third one is a power supply unit and the forth one is power out relay. I drew the all circuits by hand with a CD marker on the copper clad board.
Features
Power ON/OFF switch
Mute switch
Input switch
USB input (for Stereo Audio player)
AUX input
DVD input (5.1-channel)
Master volume: 0 to 50
6-channels volume: -10 to 10
Surround ON/OFF
Speaker mode: 5.1/2.1
All reset
Remote control
Pre-amp
The pre-amp consists of two ICs. Those are PT2323(SOP) and PT2258(DIP). It has two stereo inputs and one six-channel (5.1-channel) input. Two stereo inputs are USB and AUX. You can connect 5V stereo audio player to the USB input. I have provided the 5v ON/OFF power for this. Six-channel input is DVD.
Controller
I used to atmega328p for the controlling section. It programmed with Arduino UNO. By the end of this post you should be able to copy the code.
Used push buttons for Power ON/OFF, Mute/Unmute and Input selection. Rotary encoder for volume up/down and channel/menu select. Long press the rotary encoder's switch for the menu function. It has two power controller. First one is AMP POWER. This is for Power ON/OFF. Second one is USB POWER. This is for USB input. Platform: |
