        伽利略開發(fā)板和BeeMail(三):對(duì)象

        作者:EEPW編譯 時(shí)間:2014-11-25 來源:電子產(chǎn)品世界 收藏

          原型擴(kuò)展板有利于UNO用于初步檢驗(yàn)和板的轉(zhuǎn)移,從UNO的轉(zhuǎn)移可以確定,板的I/O引腳在嵌入式啟動(dòng)和Arduino草圖啟動(dòng)期間處于上拉狀態(tài)(取決于5V還是3.3V電壓)。

        本文引用地址:http://www.antipu.com.cn/article/265933.htm

          上面所說只是在理想狀態(tài)下的負(fù)邏輯,但馬達(dá)系統(tǒng)其實(shí)并不太適用。這里我按照GPIO的思路將引腳初始化為高電平,看看能不能找出其他辦法。

          代碼部分

          以下代碼僅為對(duì)蜜蜂基于電位計(jì)作為輸入的測(cè)試。若對(duì)蜜蜂不加干涉,程序自動(dòng)上鎖,我在這里遇到了麻煩。我去檢查串聯(lián)端口和端口是否正常,可直到現(xiàn)在我仍舊不清楚到底是哪里出了問題。
