UGalileo Gen 2 | Intengo emaphakathi | Abasabalalisi abaningi bayayithengisa |
Uma wakha ama-prototypes, ungase ufune ukukhetha i-mcu okulula ukuyithola futhi elingana nesabelomali sakho.
Umphakathi kanye Nokwesekwa
Umphakathi oqinile ungakusiza ukuxazulula izinkinga ngokushesha. Kufanele ubheke i-mcu eneziqondiso eziningi, izinkundla, namathuluzi. Lokhu kwenza kube lula ukufunda nokulungisa izinkinga. Amabhodi e-Arduino kanye ne-ESP anemiphakathi emikhulu. Ungathola izimpendulo ku-inthanethi futhi uthole usizo kwabanye abakhi.
Nalu uhlu lokuhlola olulula lokukuqondisa:
Chaza inhloso yephrojekthi yakho.
Faka kuhlu izidingo zakho zephinikhodi ye-I/O.
Hlola isivinini sokucubungula nenkumbulo.

Bheka usayizi omncane, ukusetshenziswa kwamandla, nosizo oluvela kwabanye ngaphambi kokuthi ukhethe. Bhala phansi ukuthi iphrojekthi yakho idinga ini kuqala. Khetha ibhodi elifanela uhlelo lwakho. Qiniseka ukuthi imininingwane ihambisana nendlela ofuna ukuthi idivayisi yakho isebenze ngayo.
Imibuzo Evame Ukubuzwa
Uyini umehluko phakathi kwe-microcontroller ne-microprocessor?
I-microcontroller ine-CPU, inkumbulo, nezimbobo konke ndawonye. Uyisebenzisela imisebenzi elula yokulawula. I-microprocessor ine-CPU kuphela. Itholakala kumakhompyutha adinga amandla engeziwe.
Ukhetha kanjani i-microcontroller efanele yephrojekthi yakho?
Okokuqala, bhala phansi lokho okudingwa yiphrojekthi yakho. Hlola isivinini, inkumbulo, kanye namandla angakanani ewasebenzisayo. Qiniseka ukuthi isebenza nezinzwa zakho namadivayisi. Bheka usizo oluhle kwabanye abasebenzisi. Khetha eyodwa efana nebhajethi yakho.
Ungakwazi yini ukuhlela zonke izilawuli ezincane ngolimi olufanayo?
Cha, awukwazi ukusebenzisa ulimi olulodwa kubo bonke. Amanye ama-microcontroller asebenzisa i-C noma i-C++. Abanye basebenzisa iMicroPython noma ikhodi ye-Arduino. Ngaso sonke isikhathi hlola ukuthi yiziphi izilimi ibhodi lakho elingasebenzisa ngaphambi kokuthi uqale.
Kungani ukusekela komphakathi kubalulekile lapho ukhetha i-microcontroller?
Ukwesekwa komphakathi kukusiza ukuthi ulungise izinkinga ngokushesha. Ungathola imihlahlandlela, ikhodi, nezimpendulo ku-inthanethi. Lokhu kwenza ukufunda kube lula futhi kukusiza ukuthi uqedele iphrojekthi yakho.
Imaphi amaphutha ajwayelekile lapho usebenza nama-microcontroller?
Ungase ukhethe ibhodi elinenkumbulo encane kakhulu noma i-voltage engalungile. Kwesinye isikhathi uyakhohlwa ukuhlola ukuthi iyasebenza yini nezinzwa zakho. Ngaso sonke isikhathi funda imininingwane bese uhlola ukuthi iphrojekthi yakho idinga kabili.
