Kujugunya ibikoresho bya Lego NXT kumatafari ariho (2025)

Kirby hano. Ndi umusore ukunda kumenya uko ibintu bikora, kugeza kuri sitidiyo. Igihe rero amatafari yanjye ashaje yumwana wanjye Lego NXT yatangiye gukusanya ivumbi, nabonye amahirwe. Ntabwo cyari igikinisho gusa; byari byiza rwose 32-bit ya ARM7 microcontroller yicaye mumuhondo werurutse, ategereje intego nshya. Igikorwa cyo gusimbuza ibikoresho byuruganda rwikintu gishya cyitwa "guta ibikoresho," kandi ni kwibiza gushimishije mubyuma bisubirwamo. ### Gufungura ubushobozi bwamatafari Lego Mindstorms NXT yari impinduramatwara mugihe cyayo. Ku mutima wacyo hari AT91SAM7S256 microcontroller, chip ikomeye itangaje "igikinisho." Mu gasanduku, ikoresha porogaramu yihariye ya Lego, ni nziza mu kubaka ama robo akurikiza amategeko yabanjirije gahunda. Ariko ibyo bidukikije byigenga nabyo ni imbogamizi. Kujugunya porogaramu yemewe nintambwe yambere yo kubohoza ibyuma. Ntabwo ari ugusenya amatafari; ni uguha ubuzima bwa kabiri. Mugusobanukirwa no gusimbuza software iriho, turashobora guhindura NXT muburyo rusange bushobora gukoreshwa na microcontroller ishobora gukorana na sensor na moteri yayo muburyo bushya rwose, bitarinze imbogamizi za software yambere ya Lego. Ubu buryo burahuza neza na filozofiya yubucuruzi isanzwe aho umutungo uriho wongeye gusuzumwa no kugarurwa kugirango bikorwe neza. Mu buryo bumwe, gukoresha urubuga nka ** Mewayz ** gucunga imishinga nkiyi byaba byiza, kuko bifasha gukurikirana ubuzima bwumutungo, kuva mubikorwa bisanzwe kugeza "kwibasirwa" kubwintego nshya, y'agaciro. ### Igikoresho cyo Guhindura Firmware Ntushobora kwifuriza gusa porogaramu nshya kuri chip. Ukeneye uburyo bwo kuvugana nayo. Amatafari ya NXT afasha afite icyambu cya USB, ariko kubikorwa byo murwego rwo hasi nka software yamurika, akenshi twishingikiriza kuri bootloader ya SAM-BA yubatswe muri chip. Dore uburyo bworoshye bwo kureba inzira: * ** Shiraho Itumanaho: ** Amatafari agomba gushyirwa muburyo bwa bootloader. Ibi mubisanzwe bikubiyemo gufata buto yihariye ihuza mugihe uyikoresheje, ikarenga porogaramu nkuru kandi igategura chip kugirango yakire amabwiriza mashya. * ** Hitamo uburyohe bwawe: ** Iyo bootloader imaze gukora, ugomba guhitamo icyo ugomba kwikorera. Ibyamamare bifungura-isoko mubindi birimo leJOS (itanga ibidukikije bishingiye kuri Java) cyangwa NXC (Ntabwo ari C). Ukuramo dosiye yububiko bwa porogaramu wahisemo. * ** Flashing Process: ** Ukoresheje igikoresho cyabugenewe nka software ya SAM-BA, uhuza amatafari hejuru ya USB hanyuma ugashyiraho dosiye nshya yububiko. Iyi nzira isiba porogaramu ishaje ya Lego kandi yandika bundi bushya umurenge ku murenge kuri chip ya flash yibuka. * ** Kugenzura: ** Nyuma yo kohereza, usubiramo amatafari. Niba bigenze neza, bigomba gutangira mubidukikije bishya, byuzuye hamwe na menu itandukanye kuri ecran ya LCD. > Iyi ntabwo ari imyitozo ya tekiniki gusa; ni filozofiya. Nukureba ubushobozi busanzwe muri sisitemu no kugira ibikoresho nubumenyi bwo gufungura. ### Kuva Kumatafari ahamye kugeza Dynamic Module Imbaraga nyazo zo guta ibikoresho ntabwo ari ukubona amatafari yo gukora gahunda nshya; iri guhindura byimazeyo uruhare rwayo. NXT ihinduka kuva igikoresho gifunze, intego imwe igahinduka module ifunguye, ishobora gutegurwa. * ** Ubwisanzure bwa Porotokole: ** Hamwe nibikoresho byabigenewe, amatafari ntagarukira gusa kuri protocole y'itumanaho ya Lego Mindstorms. Irashobora kuvugana na mudasobwa, indi microcontroller, cyangwa serivise igicu ikoresheje protocole isanzwe. ** * ** Kwishyira hamwe muri sisitemu nini: ** Aha niho igitekerezo kimurika. Amatafari ya NXT yasubiwemo arashobora guhinduka igice muri sisitemu nini yikora. Tekereza kuyikoresha kugirango ugenzure umukandara woroshye wa convoyeur, gucunga amatara, cyangwa gukora nkigice cya I / O. Igishushanyo cyacyo gikomeye kandi cyubatswe na moteri ituma biba byiza kuri prototyping cyangwa nubushakashatsi buhoraho. Gucunga urusobe rwibikoresho bisubirwamo niho sisitemu yo gukora modular nka ** Mewayz ** yerekana agaciro kayo, ikwemerera gukurikirana no kugenzura amatafari nkamasomo asanzwe mubikorwa byinshi byubucuruzi. Muguta ibikoresho bya Lego, ntabwo tuba twataye igice cyikoranabuhanga; turimo kubisubiramo. Turimo gukoresha imitekerereze ya modular kubikoresho, dufata NXT ntabwo ari igikinisho gishobora gukoreshwa ahubwo nka microcomputer ishoboye ishobora kwinjizwa mumishinga mishya kandi igezweho. Nurugero rwiza rwukuntu kureba ibirenze imikorere yagenewe umutungo bishobora gufungura agaciro kadasanzwe.
