1. Bonisa ukuba zeziphi izixhobo ezicwangcisekileyo ebhodini.Izixhobo ezisebhodini azikho zonke ezicwangcisiweyo ngaphakathi kwenkqubo.Umzekelo, izixhobo ezihambelanayo azivumelekanga ukuba zenze njalo.Kwizixhobo ezicwangciswayo, ukukwazi ukucwangcisa inkqubo ye-ISP kubalulekile ukugcina ukuguquguquka koyilo.
2. Jonga iinkcukacha zeprogramu yesixhobo ngasinye ukujonga ukuba zeziphi izikhonkwane ezifunekayo.Olu lwazi lunokufunyanwa kumenzi wesixhobo okanye lukhutshelwe kwi-Intanethi.Ukongeza, iinjineli zesicelo sentsimi zinokubonelela ngesixhobo kunye nenkxaso yoyilo kwaye zisisixhobo esihle.
3. Qhagamshela izikhonkwane zeprogramu ukuze usebenzise izikhonkwane kwibhodi yokulawula.Qinisekisa ukuba izikhonkwane ezicwangcisiweyo ziqhagamshelwe kwizihlanganisi okanye amanqaku ovavanyo ebhodini kolu yilo.Ezi zifunekayo kubavavanyi be-in-circuit testers (ICT) okanye i-ISP programmers ezisetyenziswa kwimveliso.
4. Ziphephe iingxabano.Qinisekisa ukuba imiqondiso efunwa yi-ISP ayiqhagamshelwanga kwezinye izixhobo ezinokungqubana nomdwelisi wenkqubo.Jonga umthwalo womgca.Kukho ezinye iiprosesa ezinokuqhuba ii-diode ezikhupha ukukhanya (ii-LED) ngokuthe ngqo, nangona kunjalo, uninzi lwabadwelisi benkqubo abakwazi ukwenza oku okwangoku.Ukuba amagalelo/iziphumo zabelwana ngazo, oku kunokuba yingxaki.Nceda unikele ingqalelo kwisibali-xesha okanye usete ngokutsha umqondiso wejenereyitha.Ukuba isignali engacwangciswanga ithunyelwa sisibali-xesha okanye ukuseta ngokutsha ijenereyitha yesignali, ifowuni isenokuhlelwa ngendlela engeyiyo.
5. Qinisekisa ukuba isixhobo esicwangcisiweyo sinikwa amandla njani ngexesha lenkqubo yokuvelisa.Ibhodi ekujoliswe kuyo kufuneka inikwe amandla ukuze icwangciswe kwinkqubo.Kwakhona kufuneka sigqibe ngale miba ilandelayo.
(1) Ngawaphi amandla ombane afunekayo?Kwimo yenkqubo, amacandelo ahlala efuna uluhlu lwamandla ombane olwahlukileyo kunendlela yokusebenza eqhelekileyo.Ukuba i-voltage iphezulu ngexesha lokucwangcisa, ngoko kufuneka kuqinisekiswe ukuba lo mbane ophezulu awuyi kubangela umonakalo kwezinye izinto.
(2) Ezinye izixhobo kufuneka ziqinisekiswe kumanqanaba aphezulu naphantsi ukuqinisekisa ukuba isixhobo sicwangciswe ngendlela eyiyo.Ukuba oku kunjalo, ngoko uluhlu lwe-voltage kufuneka luchazwe.Ukuba ukusetha ngokutsha kuyafumaneka, jonga ukusetha ngokutsha ijenereyitha kuqala, njengoko inokuzama ukuseta ngokutsha ifowuni xa ujonga umbane ophantsi.
(3) Ukuba esi sixhobo sifuna i-voltage ye-VPP, ke unikeze i-voltage ye-VPP ebhodini okanye usebenzise unikezelo lwamandla olwahlukileyo ukuze unike amandla ngexesha lokuvelisa.Iprosesa efuna i-voltage yeVPP iya kubelana ngale volthi kunye ne-digital input / output lines.Qinisekisa ukuba ezinye iisekethe eziqhagamshelwe kwi-VPP zinokusebenza kwii-voltages eziphezulu.
(4) Ngaba ndifuna imonitha ukubona ukuba amandla ombane angaphakathi kwemigaqo yesixhobo?Nceda uqinisekise ukuba isixhobo sokhuseleko siyasebenza ukugcina ezi zibonelelo zamandla ngaphakathi koluhlu lokhuseleko.
6Ngethuba lesigaba sovavanyo, ukuba ibhodi ifakwe kwi-test fixture for programming, ngoko izikhonkwane zinokudibaniswa nge-pin bed.Enye indlela kukuba ukuba ufuna ukusebenzisa i-rack tester, kwaye uqhube inkqubo yokuvavanya ekhethekileyo, kungcono ukusebenzisa ikhonkco kwicala lebhodi ukuze udibanise, okanye usebenzise intambo yokudibanisa.
7. Yiza namanyathelo okulandelela ulwazi oluyilayo.Umkhwa wokongeza idatha ethile kwi-configuration ngasemva komgca uye uxhaphake.Kwisixhobo esicwangcisiweyo esilisebenzisa kakuhle ixesha, sinokwenziwa isixhobo “esikrelekrele”.Ukongeza ulwazi olunxulumene nemveliso kwimveliso, njengenombolo yothotho, idilesi ye-MAC, okanye idatha yemveliso, yenza imveliso ibe luncedo ngakumbi, kulula ukuyigcina nokuphucula, okanye kulula ukuyinikezela ngenkonzo yewaranti, kwaye ikwavumela umenzi ukuba aqokelele ulwazi oluluncedo ngaphezulu. ubomi obuluncedo bemveliso.Iimveliso ezininzi "ezihlakaniphile" zinalo buchule bokulandelela ngokufaka i-EEPROM elula kwaye engabizi kakhulu enokucwangciswa ngedatha evela kumgca wokuvelisa okanye kwintsimi.
Isiphaluka esilungiselelwe kakuhle esifanelekileyo kwimveliso yokugqibela sinokubangela umqobo ekuphunyezweni kwe-ISP ngexesha lokuvelisa.Ngoko ke, ibhodi kufuneka iguqulwe ukuze ifaneleke kakhulu kwi-ISP kumgca wokuvelisa kwaye iphele ngebhodi elungileyo.
