Ho netefalitsoe hore mokhoa oa tlhahlobo o potlakile ebile oa sebetsa kamora ho sebelisoa ho liteko tsa PCB tsa morao-rao.

Sebopeho sa lisebelisoa tsa sistimi

Sebopeho sa sistimi ea mohlahlobi oa othomathike se bonts’oa ho Setšoantšo sa 1, se nang le microcomputer, karete ea li-interface tsa USB bus DIO, block block ea PLD, switch switch ea likhetho tse ngata, tokomane ea liteko joalo-joalo.Sistimi e ka lekola kapele liphoso tse bulehileng le tse khuts’oane tsa li-boardboard tsa single tsa PCB, tse habeli le tse ngata.

Li-microcomputer ha li na litlhoko tse ikhethang, ‘me ka kakaretso li ka sebelisa likhomphutha tse tloaelehileng. Sesebelisoa sa sistimi se amohela template ea taolo ea liindasteri ea USB-7802ADIO e theko e tlase e hlahisoang ke Tekanyo ea Hongtop le Control Technology Co, LTD. Matla a kenyelletso le tlhahiso ke 0 ~ 5V, tumellanong le standard ea USB + 5V. Usb-7802a ke 32-channel universal TTL level input / output board, e nang le likou tse kenang tsa dijithale tse 4 8-bit le likou tse 4 8-bit digital latch port, kakaretso ea lipehelo tse 32 le tse 32; E fana ka win95 / 98/2000 / NT tlasa lenaneo la liteko le lenaneo le matla la khokahano (DLL).Kaha ke bese ea USB, protocol ea USB ka bo eona e fana ka aterese ea mantlha ea boto.
