Secondly, as a fast flash storage medium, that is, without power supply data can be stored for up to 100 years, more than 10,000 duplicate records; In addition, ISD4004 has recorded a long time (up to 16 minutes, the paper used for the 8-minute ISD4004 voice chip) advantages; Finally, ISD4004 has required the development and application of peripheral circuits of the advantages of easy, This is evident from the introduction of this article reported that stations in the voice browser can be of practical application experience. １ 語音報(bào)站器硬件電路Sound Station 1 hardware circuit design 目前市場上流通的語音報(bào)站器，大多采用的不是ＩＳＤ４００４系列的芯片，這與其剛推出不久以及價(jià)格偏高有關(guān)。 Currently on the market stop the flow of voice, and mostly not used ISD4004 series of chips, which were introduced not long ago, as well as its high price-related. 但隨著ＩＳＤ４００４應(yīng)用的增多以及價(jià)格的回落，再加上ＩＳＤ４００４系列芯片本身的優(yōu)點(diǎn)，可以相信，在語音報(bào)站器中采用ＩＳＤ４００４系列語音芯片是完全可行的。 However, with the number of applications, as well as ISD4004 price drop, coupled with the ISD4004 series of chips having the advantage, it is believed that the voice browser to use stop ISD4004 series voice chips are entirely feasible. 筆者設(shè)計(jì)了該裝置的硬件電路，并進(jìn)行了上車調(diào)試，取得了較為滿意的效果。 I designed the device's hardware circuit, and a Board debug, and achieved satisfactory results. 圖1 報(bào)站器硬件電路Figure 1 stop hardware circuit connection diagram 本文討論的語音報(bào)站器主要是指裝在車上的放音電路，不包含錄音電路。 This article discusses voice stop device is installed in the car means the playback circuit, does not include the recording circuit. 而在實(shí)際應(yīng)用中，錄音電路則完成報(bào)站內(nèi)容的錄音工作，并收錄內(nèi)容存儲(chǔ)到語音芯片中。 In practical application, the recording circuit is completed stop the contents of the recording, and recorded content is stored into the voice chip. 本文主要結(jié)合ＩＳＤ４００４在放音電路中的使用介紹ＩＳＤ４００４的典型應(yīng)用。 In this paper, combined with the ISD4004 playback circuit ISD4004 introduce the use of a typical application. 本文討論的報(bào)站器主電路主要由單片機(jī)８９Ｃ５２和ＩＳＤ４００４構(gòu)成。 This article discusses the browser stop main circuit mainly by single-chip microcomputer 89C52 and constitute ISD4004. 該系統(tǒng)的硬件電路連接圖如圖１所示。 本系統(tǒng)主要分為三部分：單片機(jī)控制部分、放音部分和顯示部分。 This system is mainly divided into three parts: single-chip control of the playback part and display part. 顯示電路采用的是通過Ｐ３．０、Ｐ３．１控制的兩個(gè)７段數(shù)碼管的靜態(tài)顯示器，在此不作詳細(xì)介紹；控制部分主要由單片機(jī)８９Ｃ５２構(gòu)成，包含必要的按鍵電路、復(fù)位電路和看門狗電路等外圍電路；放音部分主要由ＩＳＤ４００４構(gòu)成，包含配套的變壓電路、功放電路等。 Display circuit used by P3.0, P3.1 to control the two paragraph 7 of the static digital tube display, and I shall not detail; control part constituted mainly by the 89C52 single-chip that contains the necessary keys circuit, reset circuit and peripheral circuits, such as watchdog circuit; playback from ISD4004 constitute some of the major, including supporting the PSA circuit, power amplifier circuit. 從圖１中可以看出８９Ｃ５２和ＩＳＤ４００４之間的連接較少。 From Figure 1 can be seen 89C52 and fewer connections between the ISD4004. 單片機(jī)的Ｐ１．０～Ｐ１．３引腳接按鍵，控制報(bào)站器工作過程中是否放音和放音內(nèi)容；Ｐ１．６接ＩＳＤ４００４的片選引腳／ＳＳ，控制ＩＳＤ４００４是否選通；Ｐ１．７接ＩＳＤ４００４的串行輸入引腳ＭＯＳＩ，從該引腳讀入放音的地址；Ｐ３．０和Ｐ３．１控制外圍顯示電路，在報(bào)站器工作過程中顯示當(dāng)前的站號；Ｐ３．２和Ｐ３．３分別接ＩＳＤ４００４的串行時(shí)鐘引腳ＳＣＬＫ和中斷引腳／ＩＮＴ。 MCU P1.0 ~ P1.3 pin access buttons, control devices stop the course of their work whether or not release the contents of tone playback; P1.6 access the ISD4004 chip select pin / SS, control whether ISD4004 strobe; ISD4004 then P1.7 serial input pin MOSI, read from the pin to the address of playback; P3.0 and P3.1 to control the external display circuit, in a newspaper, the course of their work station device displays the current number of stations; P3 .2 and P3.3, respectively, then ISD4004-pin serial clock SCLK and interrupt pin / INT. ＩＳＤ４００４芯片所需要的連接還有音頻信號輸出引腳ＡＵＤＯＵＴ，該引腳通過一個(gè)濾波電容與揚(yáng)聲器連接；ＡＭＣＡＰ為自動(dòng)靜音端，使用時(shí)通過一電容接地。 ISD4004 chips needed to connect audio signals are output pins AUDOUT, the pin through a filter capacitor connected with the speaker; AMCAP to automatically mute end, through the use of one grounded capacitor. 此外，由于ＩＳＤ４００４的工作電壓為３Ｖ，而單片機(jī)所需供電電壓為５Ｖ，因此需要采用變壓電路得到３Ｖ電壓供ＩＳＤ４００４使用。 In addition, because of the work of ISD4004 voltage 3V, while the single-chip supply voltage required for the 5V, therefore be necessary to adopt 3V voltage transformer circuit for use ISD4004. ２ 軟件2 Software Design 電路上電后，首先完成程序的初始化，隨后查詢按鍵狀態(tài)，進(jìn)入系統(tǒng)待機(jī)狀態(tài)。 Electric circuits, the first to complete the initialization procedure, and then query the status button to enter system standby mode. 如果有按鍵按下，則轉(zhuǎn)去執(zhí)行該按鍵指向的工作程序。 If you have press the button, then turn to the implementation of the key point to the work procedures. 按鍵包括放音鍵、停止鍵、加一鍵、減一鍵以及特殊語鍵。 Keys including the playback button and stop button, plus 1 key, minus one key and special key words. 在待機(jī)狀態(tài)下，如果放音鍵首次被按下，程序?qū)⑹紫扰袛嗍侨ミ€是回（公交車路徑一般是既去又回的），并點(diǎn)亮相應(yīng)的指示燈，自動(dòng)讀出第一站的放音內(nèi)容，站號顯示１。 In the standby mode, if the playback button is pressed the first time, the program will be the first to judge are or go back to (the general path of the bus are not only go further back), and the corresponding indicator light automatically read out the first stop playback of the content, Station No. 1 show. 如果不是首次按下，則首先判斷當(dāng)前站號，并以該站號為依據(jù)獲得存放該站放音內(nèi)容的首地址；然后調(diào)用放音子程序，讀入前面獲得的本站放音內(nèi)容首地址，開始放音。 If it is not the first press, then the first station to determine the current number, and the station number is based on access to stored content playback at the station and the first address; then call subroutine playback, read access to the site in front of the contents of the first playback Address to begin playback. 每一句放音完畢后，ＩＳＤ４００４的中斷引腳（２５腳）會(huì)自動(dòng)送一低電平信號。 Each sentence after playback, ISD4004 interrupt pin (25 feet) will be automatically sent to one low-level signals. 在硬件設(shè)計(jì)中，該引腳與單片機(jī)的Ｐ３．３連接，因此會(huì)引起一次中斷，在中斷子程序中有一個(gè)計(jì)數(shù)器記錄中斷次數(shù)，從而判斷何時(shí)當(dāng)前一站結(jié)束，站號加一并刷新顯示。 In hardware design, the pin and the MCU P3.3 connection, so will cause an interruption in the interruption subroutine, there is a disruption Record the number of counters, which determine when the end of the current Station 1, Station Plus together Refresh display. 加一鍵按下后，程序放音內(nèi)容轉(zhuǎn)向下一站；減一鍵按下后，則使程序放音內(nèi)容轉(zhuǎn)向上一站，相應(yīng)的站號顯示也將隨之刷新；特殊語鍵按下后，程序轉(zhuǎn)向執(zhí)行特殊語放音（譬如“拐彎請注意”等語句）；停止鍵按下，將中止當(dāng)前的放音狀態(tài)。 Add one button press, the procedures for the next shift playback content; minus one key press, after the process is turned on playback the content of one station, the corresponding station number display will also refresh; special language key press after the procedure to the implementation of the special language playback (for example, "turning Please note" and other statements); stop key press, would suspend the current playback status. 為了便于讀者對ＩＳＤ４００４應(yīng)用的理解，本文給出了部分程序。 ISD4004 in order to facilitate the readers understanding of the application, this paper some of the procedures. 該部分程序主要完成放音操作，把獲得的放音內(nèi)容的地址送到ＩＳＤ４００４中，完成放音。 Part of the procedure to complete the main playback operation, to get the address of the content playback to the ISD4004, the completion of playback.
