Nws siv los ua tus naj npawb ntawm cov sib txawv microcontroller chips muaj rau tus hobbyist tau zoo nkauj txwv. Koj yuav tsum tau siv txhua yam koj tuaj yeem tswj hwm yuav los ntawm tus xa ntawv xaj xaj tus muag khoom, thiab qhov ntawd ua rau qhov kev xaiv qis dua tus lej me me.

Tab sis lub sijhawm tau hloov pauv. Digikey teev ntau dua 16000 cov kab sib txawv hauv qab qhov 'microcontroller' tshawb nrhiav. Qhov twg yuav tsum yog tus nyiam ua haujlwm uas tsis muaj kev paub tshwj xeeb ua ntej xaiv? Nov yog qee qhov kev qhia. Cov no tshwj xeeb yog tsom rau ib tus neeg sim xaiv lub microcontroller los siv thawj zaug tsawg kawg ib nrab raws li kev kawm paub, ntau dua li ib tus neeg uas xav ua tiav txoj haujlwm tshwj xeeb. Hloov tshiab 2009-01-28: Cov Lus Qhia no tsis ntev los no tau hais hauv qee cov blog nrov, thiab tau txais cov neeg nyeem tshiab. Nco ntsoov nyeem 'cov lus pom' ua los ntawm lwm tus neeg nyeem thiab cov lus teb rau lawv; muaj ntau tus nqi hauv cov lus …

Kauj Ruam 1: Dab tsi yog "Microcontroller"?

Yog tias koj tau kawm chav kawm khoos phis tawj zoo heev, tej zaum koj tau kawm txog cov khoom tseem ceeb ntawm TXHUA lub computer:

  • Ib Lub Hauv Paus Ua Haujlwm lossis CPU. Ib feem uas ua tau zoo logic thiab lej
  • Nco. Qhov twg lub computer khaws cov ntaub ntawv thiab cov lus qhia
  • Tawm tswv yim thiab tso tawm lossis I/O. Yuav ua li cas lub khoos phis tawj txav cov ntaub ntawv ntawm nws lwm cov khoom siv thiab lub ntiaj teb tiag.

Ib tus microprocessor siv cov tshuab hluav taws xob tsim hluav taws xob los ua kom lub CPU me me me me; feem ntau yog ib qho "nti." Tus tswj hwm lub microcontroller siv cov txheej txheem ib yam los ua kom lub computer tag nrho mus rau ib qho me me (lossis cov qauv me me.) CPU, Nco, thiab I/O txhua qhov hauv pob me me li me me ntawm cov nplej. Tsuas yog txuas lub zog thiab nws pib ua nws li; xam thiab tham nrog lub ntiaj teb. Feem ntau I/O ntawm lub microcontroller tau tsom mus rau "qib qis" kho vajtse zoo li tham nrog ib tus neeg hloov pauv thiab LEDs hloov ntawm cov keyboard, txuas hauv Is Taws Nem, thiab nthuav tawm (zoo li koj lub khoos phis tawj desktop.) Microcontroller tsuas yog qhov koj xav tau, yog tias koj xav tau tham nrog tus kheej hloov pauv thiab LEDs…
