Yuav ua li cas siv lub rooj logic ntawm "7 ntu LCD" yog qhov tseem ceeb tshwj xeeb hauv peb cov khoom tsim khoom. Yog tias siv tsis raug, nws yuav ua rau kev tswj tsis tau lossis cov cim garbled. Nws suav nrog kev hloov cov lej nkag lossis cov cim rau hauv cov cim kev tswj hwm ntawm xya ntu zaub. Peb yuav tsum tau ceev faj.
Yog li dab tsi yog cov kauj ruam yooj yim los siv lub rooj logic?
1. Nkag siab txog cov qauv ntawm xya ntu tso saib:Lub xya ntu zaub muaj xya ntu LED (labeled A txog G) thiab ib qho me me (DP). Txhua ntu tuaj yeem tswj tau tus kheej kom pom cov lej lossis cov ntawv.
2. Txiav txim siab cov tswv yim:Cov tswv yim feem ntau yog tus lej (0-9) lossis tsab ntawv (AF). Koj yuav tsum txiav txim siab seb ntu twg yuav tsum tau teeb raws li tus nqi nkag.
3. Nrog rau lub rooj logic:Lub rooj logic teev lub xeev ntawm ntu sib raug rau txhua tus nqi nkag (lit lossis tawm). Piv txwv li:
Cov tswv yim 0: A, B, C, D, E, F yog nyob rau, G yog tawm
Cov tswv yim 1: B, C nyob rau, A, D, E, F, G yog tawm
Cov tswv yim 2: A, B, D, E, G yog nyob rau, C, F yog tawm
Thiab lwm yam ...
Siv cov logic tswj: Raws li lub rooj logic, siv logic circuits (xws li THIAB rooj vag, LOSSIS lub rooj vag, TSIS TXAUS SIAB, thiab lwm yam) los yog programming (xws li microcontrollers) los tswj cov teeb pom kev zoo ntawm txhua ntu.
4. Test thiab debug:Tom qab txuas lub voj voog lossis sau cov lej, sim txhua qhov kev tawm tswv yim kom paub tseeb tias cov zaub yog qhov tseeb.
Feem ntau, kev siv cov rooj logic suav nrog cov chips tsav tsheb. Yog tias koj xav paub ntau ntxiv txog kev paub txog kev txhim kho, thov hu rau peb. Peb yog Tuam Tshoj LCD npo Hoobkas nrog cov kws tshaj lij engineering thiab cov kab ntau lawm. Peb tuaj yeem muab cov kev pabcuam zoo rau koj tshaj li qhov koj xav tau!
