基於stc12c5a60s2的智能語音識別天氣時鐘

設備說明:本設備使用具有兩個usart串口的stc12c5a60s2作爲MCU主控，SNR3512作爲語音識別模塊，JQC80作爲語音模塊，esp8266作爲聯網模塊。本設備可以實現非特定人聲的語音識別，並且在識別之後進行自動聯網獲取目標城市的時間和未來七天的溫度。在本裝置中，可以在上電之後按下key1或者呼叫"小星，小星"啓動SNR3512模塊，之後呼叫"啓動引擎"，開啓聯網。聯網成功後自動播放時間和溫度。天氣API用的https://www.sojson.com/blog/234.html，因爲這個天氣API需要進行解析，利用單片機進行解析比較麻煩。所以就讓朋友搭建了一個新的網址，在自己搭建的網址中先把API中的天氣提取完成。這樣我的設備直接訪問這個網址就可以獲取到時間和天氣了。操作說明：
1.插上電源，會啓動OLED並且播放聲音語句:"歡迎使用小桔智能天氣時鐘"
2.按鍵Key1或者呼叫“小星小星”+"啓動引擎"，播放語句"小桔正在努力聯網中"
3.oled最下面會依次顯示step1-ok,step2-ok,step3-ok,step4-ok,step5-ok.step6-ok.,step7-0k。
其中，step2-step3需要進行大概10~20s的時間，之後就會播放"聯網成功"，否則播放"聯網失敗，重新聯網中"
，聯網失敗需要按下key1進行重新聯網，或者重新啓動設備。
4.到step7-ok後則會播放時間和天氣，此時播放結束後可以按key1或者呼叫"小星，小星"，則可以重新播放時間。如果需要退出聯網狀態，按下key2，顯示step8-ok。

最後：本代碼還有不少的地方需要進行完善，有興趣的夥伴可以自己動手進行試驗哦。
