1. 單片機STC89C52+語音晶元ISD1760+數碼管顯示錄音或放音時長
你指的是顯示錄音的起始、結束地址嗎？
2. 基於51單片機和ISD1760的c程序
這個可供參考http://www.ourdev.cn/bbs/bbs_content.jsp?bbs_sn=917470&bbs_page_no=1&bbs_id=1006
3. 使用51單片機控制ISD1760實現語音播放時，1760的SP+不能使8歐0.25w的揚聲器發聲，但是通過9012三極體放大後
驅動能力還是比較低的，一般可以加一個LM386來放大一下。
4. 單片機控制ISD1760的程序是否要給ISD1760驅動程序
貌似不是用驅動，直接向1760的SS,SCLK,MOSI,MISO埠寫入數據，單片機就可以控制1700的語音錄制和播報。因為單片機是通過這四個引腳和它通信。
ISD1760模塊淘寶上有賣的。源碼喝原理圖可以在網上找。
5. isd1760語音晶元的上位機軟體如何使用
你好！
1、首先 isd1760 只是一個語音晶元，不具備MCU的功能
2、isd1760 接入單片機，然後用單片機發指令控制晶元
3、上位機通過串口和單片機連接，通過上位機間接控制晶元
6. 基於52單片機ISD1760語音晶元的原理圖和程序代碼。
