Programmer PIC: hauj lwm, los ntaus

PIC-microcontrollers ua los ntawm cov American lub tuam txhab Microchip Technology Inc. Tsiaj ntawv PIC txhais tau tias ib tug peripheral interface xws li. PIC-microcontrollers yog electrically programmable EPROM cov neeg siv. Lawv tsiag ntawv los ntawm tsawg heev zog noj, muaj kev kawm siab, zoo-tsim RISC-architecture, tej tiav, yam tsawg kawg nkaus qhov ntev thiab tsis muaj nqi. Microcontroller Firmware yog nqa tawm siv ib tug ntaus ntawv xws li ib tug programmer PIC.

piav qhia

Rau kev siv tswv yim ntawm tej chips tus neeg siv yuav tsum tau ib tug pheej yig thiab pheej yig cuab yeej. Muaj ntau ntau kev daws teeb meem xws li (ob amateur thiab coj mus muag version). Nyob rau hauv no tsab xov xwm peb yuav saib ib tug ncaj yooj yim programming PIC, tsim los ntawm Microchip Technology Inc. Nws yuav tsum tau muab sau tseg tias, tsis zoo li cov improvised amateur pab kiag li lawm, qhov no ntaus ntawv yog ib tug tag nrho cov debugger, nws kuj muaj ib tug xov tooj ntawm ntxiv zog analizatorskih.

Programmer PIC-xws li yog raws li nyob rau hauv ib tug PIC18F2550 nti los pab txhawb USB 2.0 nuj nqi. Lub Circuit Court tau txais hluav taws xob tam sim no los ntawm lub USB connector thiab, raws li, tsis yuav tsum tau ntxiv hwj chim qhov twg los. Los ntawm no chaw nres nkoj, koj yuav hloov lub firmware nti. PIC programmer muaj me me zuag qhia tag nrho qhov ntev thiab yog tsim raws li ib tug tseem ceeb FOB. Nyob rau hauv lub cev muaj peb LEDs uas qhia cov kev khiav hauj lwm hom ntawm tus dais, thiab ob tug slots: ib qho rau txuas mus rau ib tug tus kheej lub computer, thiab lub thib ob - ncaj qha mus rau lub microcontroller.

Qhov no PIC programmer rau nyob rau hauv-Circuit Court programming thiab debugging ntawm feem ntau nti tuam txhab uas muag "microchip". Qhov no ntaus ntawv sau nyob rau hauv nws tus kheej, los yog plhaub kev pab cuam, los yog lub MPLAB IDE software. Nyob rau hauv thawj rooj plaub (siv PICkit 2 Programmer) ntaus ntawv tej zaum yuav lwv, muaj tseeb nco teem tiv thaiv code flash, kho kom raug tus txheem ntawm microcontrollers. Thiab sau ntaub ntawv nyob rau hauv ib tug nco nti, nruab tus tsav tsheb thiab Keeloq lub lag luam. Nyob rau hauv tas li ntawd mus rau cov yooj yim zog, lub programmer yuav tsim ib tug nqi ntawm PIC pab kiag li lawm voltage nyob rau hauv ntau ntawm 2.5 mus 5 volts, nrog 0.1 kauj ruam B.

lub sij hawm

Nrog rau qhov no feature, nws yuav tau mus debug cov tsim pab kiag li lawm tsis muaj disconnecting los ntawm cov programmer. Lub apparatus tso cai rau lub USB chaw nres nkoj rau qhov teeb meem los ntawm nominal tam sim no tus nqi rau 100 ma, yog hais tias qhov daim duab yog ua zoo tshaj, cov Circuit Court yuav txiav tua. Tsis tas li ntawd, lub programmer yog tau calibrate lub voltage USB-chaw nres nkoj tsheb npav raws li ib tug tshwm sim ntawm tus dais no tej zaum yuav muab mus rau ib tug tam sim no voltage nqi. Qhov no thaum kawg muaj ib tug zoo ntxim rau nws ua hauj lwm. Rau pab kiag li lawm muaj ib tug sab nraud pib dua, lub programming mem tes tswj wrapper cia microcontroller pib dua. Nyob rau hauv cov cuab yeej rau zaub mov plhaub kev pab cuam, koj yuav khiav cov kev xaiv Siv VPPFirst Program nkag, microcontrollers yuav tsum tau, lub configuration uas tsis pub nkag mus rau lub cajmeem hom.

Xam tias yog PIC programmer yog ib tug haib, ntau yam lub cuab tam rau debugging "microchip" microcontrollers. Nws muaj ib tug nqi pheej yig, thiab yog hais tias qhov kev kawm, muaj peev xwm muab tau yooj yim dua, ua tsaug rau cov ntaub ntawv muab rau lub tuam txhab website.
