基于STC12C2502AD單片機控制8路繼電器動作的程序問題

ID:989451 · 發(fā)表于 2021-12-8 22:39

為了工作方便想開發(fā)一個8繼電器的開關(guān)電源作為工具使用；
于是買了帶單片機的模塊，以及拿到C 語言源代碼，如下。但是由于新手+基礎(chǔ)薄弱，在修改一些語句后，編譯仍然出現(xiàn)warnings，雖生存hex文件，但是XCOM串口工具通過給的協(xié)議無法調(diào)試單片機模塊；
想在這跟大佬請教，指出錯誤。

如果是： STC12C2502AD
首先， include STC12C2502AD 的頭文件，
然后， STC12C2502AD 需要設(shè)置端口模式，你可以參考手冊。

然后，最關(guān)鍵的警告，你調(diào)用了 Eeprom 相關(guān)的函數(shù)，但是，你并沒有提供實體函數(shù)，僅僅聲明了，這么一個函數(shù)，內(nèi)部是空的。
