音乐播放器设计说明

音乐播放器说明书音乐播放器设计说明1、设计目的充分利用EITS2003 多用途EDA 开发实验平台的设计资源，完成一个比较复杂的FPGA 设计方案，增强对FPGA 设计的更深理解，提高设计水平，为今后的更复杂的FPGA 设计实践打下坚实的基础。

2、设计概述EITS2003 多用途EDA 开发实验平台给我们提供了丰富的设计资源。

它的核心器件为Xilinx 公司的Spartan-IIE 系列的FPGA 芯片，且在FPGA 周围提供了丰富的资源：有串口、PS/2 接口、VGA 接口、LED 和七段数码管显示、拨码开关和按钮、AT89S52 单片机、SRAM、I2C、A/D D/A 转换、扬声器、电源、电源晶振等。

这就为我们的设计提供了丰富的选择。

考虑到以后实践的需要，且又要达到一定的难度，我们选择了把几种常用接口PS/2、LED 显示结合的一个电路。

虽然设计并不是很复杂，但其实践意义是很大的。

3、设计方案说明3.1 总体方案我们设计的总体思想是：利用EITS2003上的拨码开关选择不同的歌曲进行播放，并在相应的七段数码管及LED显示正在播放的音阶。

3.2 关键部分说明3.2.1 音乐电路音乐电路原理：组成乐曲的每个音符的频率值（音调）及持续时间（音长）是实际乐曲演奏的两个基本数据。

因此只要控制输出到扬声器的激励信号的频率和信号的持续时间就可以发出持续的乐曲声。

频率的高低决定了音调的高低。

音乐的十二平均率规定：每连个八度音（如简谱中的中音1与高音1）之间的频率相差一倍。

在两个八度音之间，又可以分为十二个半音，每两个半音的频率比为12sqr(2)。

另外，音名A（简谱中的低音6）的频率为440Hz，音名B到C之间，E到F之间为半音，其余为全音。

由此简谱中从低音1到高音1之间的每个音名对应的频率如下表3所示：3.3 具体实现 3.3.1 顶层模块TOPswitch1,2,3resetl1,2,3,4,5,6,7dig1,2,3LEDspeaker clock顶层模块的输入输出如上图所示。

If the current exceeds 40µA,the OVP protection is triggered (Dynamic OVP), and the external power transistor is switched off until the current falls approximately below 10µA.However, if the overvoltage persists, an internal comparator (Static OVP) confirms the OVP condition keeping the external power switch turned off (see fig. 4).Finally, the overvoltage that triggers the OVP function is:∆V out = R 1 · 40µA.Typical values for R 1, R 2 and C are shown in the application circuits.

Vertical Tracking Force setting (VTF)* This setting is only neccessary when you decided to repalce your cartridge. For factory fitted cartridge, VTF was perfectly pre-set already.Before setting the Vertical Tracking Force, confirm the exact weight of your cartridge.Pushing carefully, move the counterweight onto the rear end of the counterweight support rod. Place thestylus pressure gauge onto the platter. To set the required VTF, lower the tonearm lift lever as indicated in the illustration and place the tip of the stylus exactly in between the two points marked 15mN and 20mN. If the stylus gauge becomes level, then the correct pressure has been achieved. However, if the there is insufficient or excessive pressure the gauge will either not move or tilt down. Moving the counterweight (6) away from the cartridge will reduce pressure and towards will increase pressure. Finally secure the counterweight (6) using hexagonal key provided.4. Speed controlThe turntable is equipped with a three-position switch for ON/OFF and electronic speed change. To play records at 33 r.p.m. press the switch (16) to the front side to position no. 1. To play records at 45 r.p.m. press the switch (16) to the rear side to position no. 25. Maintenance and cleaningYour record player requires little or no regular maintenance. Remove dust with a slightly moistened antistatic cloth. Never use a dry cloth because this will create static electricity which attract more dust! Antistatic cleaning fluids are available at specialist stores but must be applied sparingly to avoid damage to rubber parts. It is recommended to fit the needle cover before cleaning or maintenance is carried out to avoid damage. If the player is not used over a long period of time the drive belt can be removed to prevent unequal stretching.Controls, features and connections1 PHONO OUTPUT CABLE2 POWER SUPPLY SOCKET__________________________________________________________________________________________Connection to the amplifierThe record player has a captive tonearm signal lead for connection to the amplifier.

Music ShieldUser Manual 1.Music Shield is an Arduino expansion board for playing/recording audio, features onboard audio codec chip VS1053B and a TF card slot, supports common used audio formats.Features:●Arduino standard interfaces,compatible with Arduino boards likeArduino UNO, Leonardo, NUCLEO,XNUCLEO●Supported formats :MP3/AAC/WMA/WAV/MIDI, etc.●Onboard TF card slot, audio files in TFcard can be played directly●Onboard MIC for recording, withstandard 3.5mm 4-segmentheadphone jack●Onboard voltage level converter74VHC125, compatible with 3.3V/5VMCUs●One-key control, play music andadjust volume easily by thenavigation key ●Features I2S and MIDI interface forfunctional expansion●Note : Limited by the transmissionspeed and memory shortage, Arduinoboards like UNO and Leonardo canneither play WAV files, nor use therecording function. NUCLEO or Dueare recommended.Note : Limited by the transmission speed and memory shortage, Arduino boards like UNO and Leonardo can neither play WAV files, nor use the recording function. NUCLEO or Due are recommended.12.2.1.VS1053BThe Music Shield features a VS1053 audio decoder-and-encoder chip designed by VLSI from Finland, of which internal structure is shown in the following figure:Control interface: the VS1053 communicates with a MCU through SPI, of which can be controlled by 7 data lines. They are:XRSET Active low asynchronous reset, schmitt-trigger inputXCS Chip select input (active low)XDCS Data chip select (active low)SI Serial inputSO Serial outputSCK Clock for serial busDREQ Data request, input bus. If DREQ is high, VS1053b can take at least 32 bytes of SDI data or one SCI command. DREQ is turned low when the stream buffer is too fulland for the duration of a SCI command. At this point sending data or commandsshould be stopped.23Audio output: The I2S pins and earphone are used for audio output from VS1053. TheLEFT/RIGHT pads are used for Left/Right channel output. The GBUF pad is used for Common buffer for headphones. The I2S output pins (LOROUT, MCLK, SCLK, SDTA) are retained on the Music shield.Recording: MICP/MICN, the differential mic input; LINE1/LINE2, the Line-in 1/2. The mic on Music Shield is connected to MICP/MICN and the earphone is connected to LINE2.Note: please refer to the section Packages and Pin Descriptions of VS1053b datasheet.2.2. Serial Protocol for Serial Command Interface (SCI)The serial bus protocol for the Serial Command Interface SCI (Chapter 8.6) consists of an instruction byte, address byte and one 16-bit data word. Each read or write operation can read or write a single register. Data bits are read at the rising edge, so the user should update data at the falling edge. Bytes are always send MSb first. XCS should be low for the full duration of the operation.The operation is specified by an 8-bit instruction opcode. The supported instructions are read and write. See table below.SCI Read(See the Figure 6 of VS1053b datasheet)VS1053b registers are read from using the following sequence. First, XCS line is pulled low to select the device. Then the READ opcode (0x3) is transmitted via the SI line followed by an 8-bit word123456789101112133031141516170000001100003210000000000000000151410Xinstruction (read)addressdata outXCSSCKSI SO don’t caredon’t careDREQexecution4address. After the address has been read in, any further data on SI is ignored by the chip. The 16-bit data corresponding to the received address will be shifted out onto the SO line.XCS should be driven high after data has been shifted out.DREQ is driven low for a short while when in a read operation by the chip. This is a very short time and doesn’t require special user attention.SCI Write(See the Figure 7 of VS1053b datasheet)VS1053b registers are written from using the following sequence. First, XCS line is pulled low to select the device. Then the WRITE opcode (0x2) is transmitted via the SI line followed by an 8-bit word address.After the word has been shifted in and the last clock has been sent, XCS should be pulled high to end the WRITE sequence.2.3. SCI RegisterVS1053 has 16 SCI registers in total. They are used to control the operation of VS1053b, as shown in the following figure:123456789101112133031141516171032101XaddressXCSSCKSI1514data outSO0Xinstruction (write)DREQexecutionHere are brief introductions about the main registers. (Please see the section SCI Registers of VS1053b datasheet for more details)SCI_MODE Register: it is used to control the operation of VS1053b.5These bits are the primary focus of the present register:2nd bit: SM_RESET Soft reset,12th bit: SM_ADPCM ADPCM recording active,14th bit: SM_LINE1 MIC / LINE1 selector.SCI_BASS Register: it is used to control the sound effect of VS1053b.The sound effect can be set by modifying the bit of the register.SCI_CLOCKF Register: it is used to set the frequency, multiplier, etc, of the clock.SCI_VOL Register: it is a volume control for the player hardware. The most significant byte of the volume register controls the left channel volume, the low part controls the right channel volume. The channel volume sets the attenuation from the maximum volume level in 0.5 dB steps. Thus, maximum volume is 0x0000 and total silence is 0xFEFE.6SCI_HDAT1/SCI_HDAT0 Register: After IMA ADPCM recording has been activated, registers SCI HDAT0 and SCI HDAT1 have new functions. The IMA ADPCM sample buffer is 1024 16-bit words. The fill status of the buffer can be read from SCI HDAT1. If SCI HDAT1 is greater than 0, you can read as many 16-bit words from SCI HDAT0. If the data is not read fast enough, the buffer overflows and returns to empty state.2.4.Playing Audio FilesIt is easy to use VS1053 as a hardware audio decoder to play audio files, only requires 3 steps to implement.1)Reset VS1053The hardware and software reset at the boot up time and initialize the VS1053, preparingto decode the next music file.2)Configure VS1053 registersThe registers to be configured are Mode Register (SCI_MODE), Clock Register (SCI_CLOCKF)Bass Register (SCI_BASS), Vol Register (SCI_VOL Register), etc.3)Transmit audio dataIf configuration complete, audio data can be transmitted to VS1053 constantly. VS1053 willdecode the audio data, if decodable, until the audio data transmitting is finished. (Note:only if the DREQ is high can VS1053 receive data.)2.5.RecordingThe steps of Recording and playing are similar, first reset and then configure the related registers. The registers to be set mainly are:IMA ADPCM recording mode is activated by setting bits SM RESET and SM ADPCM in SCI MODE. Line input 1 is used instead of differential mic input if SM LINE1 is set.7(The mic on Music Shield is connected to differential mic input while the earphone is connected to Line input 2.)Before activating ADPCM recording, user must write the right values to SCI AICTRL0 and SCI AICTRL3. These values are only read at recording startup. SCI AICTRL1 and SCI AICTRL2 can be altered anytime, but it is preferable to write good init values before activation. See the section Activating PCM / ADPCM Recording Mode of VS1053b datasheet for more details.If the registers have been configured correctly, the audio data can be read constantly. If SCI HDAT1 is greater than 0, you can read as many 16-bit words from SCI HDAT0. (See the section Reading PCM / IMA ADPCM Data of VS1053b datasheet)Note: the recording data do not contain any RIFF header of the audio file. So to make your recording data a RIFF / WAV file, you have to add a header before the actual data. See the section Adding a PCM RIFF Header of VS1053b datasheet.2.6.Real-Time MIDIIf GPIO0 is low and GPIO1 is high during boot, real-time MIDI mode is activated. In this mode the PLL is configured to 4.0×, the UART is configured to the MIDI data rate 31250 bps, and real-time MIDI data is then read from UART and SDI. Both input methods should not be used simultaneously. If you use SDI, first send 0xff and then send the MIDI data byte.(The RX of UART on the Music Shield is connected to MIDI input.)Note: If GPIO1 is not high, Real-Time MIDI can also be started with a small patch code using SCI.893. 3.1. Pin Descriptions1) D11, D12 and D13 are the MISO, MOSI and SCLK buses of the SPI interface by default. 2) A0, A1, A2 and A3 are connected to the XRESET, DREQ, XDCS and XCS of VS1053. 3) D10 and D9 are the CS and SD_Detect pins of the SD card.4) D7,D6,D5,D4 and D3 correspond to the button Down (Volume -), Left (Previous), Middle (Play/Stop/Record), Right (Next), Up(Volume +).5) D8 is the LED indicator (it blinks when the module plays or records).3.2.How to useIn this section, we will illustrate the applications of this shield by using 2 kinds of development boards.1. Playing Audio1) Copy some audio files to the root directory of a TF card and insert it into the TF socket of a Music Shield.2) Connect the development board to a PC.3) Compile and program the Music Shield Player Demo.4) Run the serial monitor software (PuTTY, SecureCRT, Arduino Serial Monitor, etc.) Set the software as: Baud: 9600, Data bits: 8, Stop bits 1; Parity: None, Flow control: None. 5)Plug in an earphone and you will hear the music.
