stm32f103c8t6+rc522 ic卡識(shí)別程序

ID:547792 · 發(fā)表于 2020-5-6 21:57

基于stm32的IC卡識(shí)別，做的是個(gè)門(mén)禁系統(tǒng)，用的rc522模塊，設(shè)別IC卡卡號(hào)，判斷卡號(hào)為管理員還是員工，進(jìn)行開(kāi)門(mén)操作，用的12v電磁鎖，添加了時(shí)鐘，來(lái)分開(kāi)上班時(shí)間和下班時(shí)間，以及假日模式，假日模式管理員卡和密碼同時(shí)正確才可打開(kāi)門(mén)，下班時(shí)間管理員就可以打開(kāi)。最后加了電池，當(dāng)外部電源斷開(kāi)，電池自動(dòng)供電，由外部電源電池不供電。

制作出來(lái)的實(shí)物圖如下：
