Isikhokelo sokugqibela sePrototyping yePCB usebenzisa iiNkqubo zoLawulo lweXesha elililo

Intshayelelo:

Iibhodi zesekethe eziprintiweyo zeprototyping (PCBs) zisebenzisa iinkqubo zokulawula ixesha langempela zinokuba ngumsebenzi onzima nonzima. Nangona kunjalo, ngezixhobo ezifanelekileyo, ulwazi, kunye nobuchule, inkqubo inokugqitywa ngempumelelo.Kwesi sikhokelo sibanzi, siza kukuhamba ngamanyathelo asisiseko kunye neendlela ezingcono zokuchwetheza ii-PCBs usebenzisa iinkqubo zolawulo lwexesha lokwenyani.Nokuba uyinjineli yobuchwephesha okanye i-hobbyist yombane, le bhlog iya kukunika ulwazi oluyimfuneko ukuze ujike izimvo zakho zePCB zibe yinyani.

1. Qonda uyilo lweprototype yePCB:

Ngaphambi kokuntywila kwihlabathi leenkqubo zolawulo lwexesha lokwenyani, kubalulekile ukuba uqhelane neziseko ze-PCB prototyping. IiPCB ziyinxalenye ebalulekileyo yezixhobo zombane ezininzi, ezibonelela nge hub yoqhagamshelo kunye neesekethe. Ukuchwetheza ngempumelelo iiPCB, kufuneka uqonde inkqubo yoyilo, iileya zePCB, amacandelo, kunye nobuchule bokuvelisa. Olu lwazi luya kwenza isiseko sokudibanisa iinkqubo zolawulo lwexesha lokwenyani kwiiPCB.

2. Khetha izixhobo ezifanelekileyo kunye namacandelo:

Ukwenza iprototype yePCB usebenzisa inkqubo yolawulo lwexesha lokwenyani, kufuneka ukhethe izixhobo ezifanelekileyo kunye namacandelo. Okokuqala, udinga isoftware yoyilo yePCB ethembekileyo ebonelela ngezakhono zokulinganisa ixesha lokwenyani. Ezinye iinketho zesoftware ezidumileyo ziquka uKhozi, iAltium, kunye neKiCad. Emva koko, khetha i-microcontroller okanye iprosesa ehambelana neemfuno zeprojekthi yakho. Ukhetho oluqhelekileyo lubandakanya iArduino, iRaspberry Pi, kunye neebhodi zeFPGA.

3. Yila uyilo lwePCB:

Uyilo lwePCB ludlala indima ebalulekileyo ekudityanisweni ngempumelelo kweenkqubo zolawulo lwexesha lokwenyani. Qinisekisa ukuba amacandelo abekwe ngokwesicwangciso ukunciphisa ukuphazamiseka kophawu kunye nokwandisa ukusebenza. Qwalasela izinto ezifana nobude bomkhondo, amandla kunye neenqwelomoya zomhlaba, kunye nokuchithwa kwe-thermal. Sebenzisa izixhobo ze-EDA (i-Electronic Design Automation) ukuncedisa kwinkqubo yoyilo kunye nemithetho yoyilo ebonelelwe ngumenzi ukuphepha imiba yokuvelisa eqhelekileyo.

4. Idityaniswe nenkqubo yolawulo lwexesha lokwenyani :

Iinkqubo zolawulo lwexesha langempela zinokubeka iliso ngokuchanekileyo kunye nokulawula izixhobo ze-elektroniki. Ukudibanisa inkqubo enjalo kuyilo lwePCB, kufuneka uqonde iindlela ezahlukeneyo zonxibelelwano ezifana ne-SPI, I2C, UART, kunye ne-CAN. Olu nxibelelwano luvumela unxibelelwano olungenamthungo kunye nabenzi boluvo, ii-activators, kunye nezinye iiperipherals. Kwakhona, qonda iilwimi zeprogram ezifana neC / C ++ kunye nePython njengoko ziqhele ukusetyenziswa ukubhala i-firmware esebenza kwii-microcontrollers.

5. Uvavanyo kunye nokuphindaphinda :

Nje ukuba iprototype ilungile, kubalulekile ukuvavanya ngokucokisekileyo ukusebenza kwayo. Sebenzisa izixhobo zokulungisa iimpazamo kunye nesoftware ukuqinisekisa ukuba iinkqubo zolawulo lwexesha lokwenyani zisebenza njengoko kulindelekile. Vavanya iimeko ezahlukeneyo zokuqinisekisa ufundo lwenzwa kunye nokuqinisekisa ulawulo olululo lwe-actuator. Ukuba kuvela nayiphi na imiba, hlalutya ingxaki kwaye uqhubeke uphindaphinda ude ufezekise umsebenzi ofunekayo.

Isiphelo :

Ii-PCB zePrototyping ezineenkqubo zolawulo lwexesha lokwenyani zivula amathuba angapheliyo okudala izixhobo zombane ezintsha. Ngokulandela iinkqubo ezisele zisetyenzisiwe, usebenzisa izixhobo ezifanelekileyo, kunye nokufunda rhoqo kwaye uphindaphinda, ungaziguqula izimvo zakho zibe ziiprototypes ezisebenza ngokupheleleyo. Yamkela umngeni, yiba nomonde, kwaye wonwabele inkqubo yokuguqula uyilo lwePCB yakho ibe yinyani.
