基于5單片機(jī)控制的語音報時萬年歷課程設(shè)計

1、基于51單片機(jī)控制的語音報時萬年歷-20/11/2013 SDU(WH)1 實驗要求運(yùn)用單片機(jī)及相關(guān)外設(shè)實現(xiàn)以下功能：1） 萬年歷及時鐘顯示2） 時間日期可調(diào)3） 可對時間進(jìn)行整點(diǎn)報時和隨機(jī)報時2 方案分析根據(jù)實驗要求，選用STC公司的8051系列，STC12C5A16S2增強(qiáng)型51單片機(jī)。此單片機(jī)功能強(qiáng)大，具有片內(nèi)EEPROM、1T分頻系數(shù)、片內(nèi)ADC轉(zhuǎn)換器等較為實用功能，故選用此款。實驗中，對日期和時間進(jìn)行顯示，顯示的字符數(shù)較多，故選用12864LCD屏幕。該屏幕操作較為便捷，外圍電路相對簡單，實用性較強(qiáng)。為了實現(xiàn)要求中的時間日期可調(diào)，故按鍵是不可缺少的，所以使用了較多的按鍵。一方面，單片

2、機(jī)的I/O口較為充足；另一方面，按鍵較多，選擇的余地較大，方便編程控制。實驗中，并未要求對時間和日期進(jìn)行保存和掉電續(xù)運(yùn)行，所以并未添加EEPROM和DS12C887-RTC芯片。實際上，對萬年歷來說，這是較為重要的，但為了方便實現(xiàn)和編程的簡單，此處并未添加，而是使用單片機(jī)的定時器控制時間，精度有差別。且上電默認(rèn)時間為2014-01-01 09:00:00 之后需要手動調(diào)整為正確時間。要求中的語音報時功能，這里選用ISD1760芯片的模塊來幫助實現(xiàn)。此模塊通過軟件模擬SPI協(xié)議控制。先將所需要的聲音片段錄入芯片的EEPROM區(qū)域，之后讀出各段聲音的地址段，然后在程序中定義出相應(yīng)地址予以控制播放哪
