Ib lub Board-thawj microcontroller keeb kwm

Mar 11, 2019


Cov Board-ib-qho microcontrollers tshwm nyob rau xyoo 1970s, thaum pom cov microprocessors thaum ntxov, xws li 6502 thiab Z80, [1] ua kom nws tsim kom muaj ib qho kev tswj xyuas ntawm ib lub rooj saib xyuas tib si, thiab muaj nqis rau kev siv lub computer mus rau ib txoj hauj lwm me me.


Hauv lub Peb Hlis 1976, Intel tshaj tawm ib lub tshuab computer ib qho khoom ua ke ua ke nrog txhua yam ntawm cov khoom txhawb kev xav tau rau lawv 8080 microprocessor, nrog rau 1 kilobyte RAM, 4 kilobytes ntawm tus neeg siv tshuab hlwb hlau, thiab 48 kab khiav mus rau I / O nrog kab tsav tsheb. Lub rooj tsavxwm tseem muaj kev nthuav dav los ntawm lub tsheb npav, tab sis yuav siv tau yog tias tsis muaj daim npav qhov qhib siab thaum daim ntaub ntawv tsis tas yuav kho vaj tse ntxiv. Kev txhim kho software rau qhov system no yog hosted ntawm Intel's Intellec MDS microcomputer development system; qhov no yog muab sib dhos thiab PL / M yug, thiab tso cai rau hauv-circuit emulation rau debugging.


Cov txheej txheem ntawm no era yuav tsum muaj ib tug xov tooj ntawm cov chips txhawb kom muaj nyob sab nraum ntawm tus processor. RAM thiab EPROM tau cais, feem ntau yuav tsum tau tswj xyuas kev nco lossis kho tshiab circuitry rau kev nco nco. I / O processing tej zaum tau raug tsim los ntawm ib qho ntiv tes xws li 8255, tab sis feem ntau yuav tsum tau muaj ob peb daim ntxiv.


Ib leeg-pawg microcontroller sib txawv los ntawm ib lub PC-ib lub computer uas nws tsis muaj lub tswv yim davhlau rau neeg siv thiab cov chaw cia ntau qhov chaw uas muaj ntau lub tshuab computer. Muab piv rau ib pawg tswj hwm microprocessor board, lub koomhaum microcontroller yuav qhia txog cov kev tswj digital thiab analog interconnections rau qee qhov kev tswj, yog tias ib lub rooj tsav xwm muaj peev xwm los ntawm tsuas muaj qee qhov tsis tshua muaj lossis tsis muaj cov khoom siv tawm los yog cov khoom siv tawm analog. Lub rooj tsav xwm loj hlob tshwm sim los ntawm kev nthuav tawm los yog cob qhia rau qee tus neeg ua haujlwm processor thiab, yog li ntawd, kev siv hauv kev ua haujlwm tseem ceeb dua kev ua haujlwm sab nraud.
