I-LCD 20X4

Isikhokelo esibanzi sibonisa I-20x4 LCD Veza, ugubungele inkcazo yayo, izicelo, ukuqhubela phambili, kunye nokucofa ingxaki. Sinemicimbi yezobugcisa, sinika imizekelo esebenzayo kunye nezixhobo zokukunceda udibanise ngokupheleleyo olu phawu lwakho luqulathe iiprojekthi zakho. Funda indlela yokukhetha ilungelo I-20x4 LCD Ngeemfuno zakho kwaye woyise imiceli mngeni.

Yintoni i-20x4 LCD?

A I-20x4 LCD . Yinxalenye eqhelekileyo kwiinkqubo ezifakelweyo, iirobhothi, kunye nezinye izicelo ezahlukeneyo apho kufuneka ulwazi olufunekayo. Ezi miboniso zixabisa kakhulu kwaye zilula ukunxibelelana nabaxhasi be-microtrolfle, ibenza babe ngabakhethiweyo beHobbyishini kunye neengcali ngokufanayo. Isibonisi sisebenzisa unxibelelwano olufanayo lwendlela yokufakelwa, efuna idatha eliqela kunye ne-pins yokulawula ukunxibelelana.

Inkcazo ephambili kunye neempawu ze-20x4 LCD

Umahluko oninzi we I-20x4 LCD Zikho, kodwa izinto eziqhelekileyo zibandakanya:

• Ubungakanani bobuqili: Iimpawu ezingama-20 kumgca ngamnye, imigca emi-4 iyonke.
• Ubungakanani bomlinganiswa: Ngokwesiqhelo i-5x7 okanye i-5x8 pixels yomlinganiswa ngamnye.
• I-Intanethi
• Isibane esingasemva: sihlala siquka isibane se-LED yokuphucula ukubonakala; Ingafumaneka kwimibala eyahlukeneyo (i.G., iblowu, iluhlaza, emhlophe).
• Uhlengahlengiso: Iimodeli ezininzi zibonelela ngolungelelwaniso loThengiso lwePoliselo olwenziwe ngokugqibeleleyo.
• Uncedo lwamandla: Ngokwesiqhelo usebenza kwi-5V.

Ukukhetha i-20x4 ye-LCD4 ye-LCD

Ukukhetha ngokufanelekileyo I-20x4 LCD Kuba iprojekthi yakho ibandakanya ukuthathela ingqalelo izinto ezininzi:

• Uhlobo lwasemva kunye nombala: Khetha isibane esingasemva esibonelela ngokukhanya okwaneleyo kunye nokubonakala kwendawo yakho yesicelo.
• Uhlobo lwe-Intanethi: Ukuqinisekisa ukuhambelana nezakhono zakho ze-hicrocontroller.
• Ifonti yefonti
• Umbane oSebenzayo: Qinisekisa ukuba i-voltage yokusebenza isebenza ihambelana nomsebenzi wakho.

Ukunxibelelanisa i-20x4 LCD ene-microcontroller

Ukudibanisa A I-20x4 LCD Ngokwesiqhelo kubandakanya ukudibanisa ezi pin zilandelayo:

• I-VSS (umhlaba): Qhuliswa emhlabeni.
• I-VDD (iMandla): iqhagamshelwe kunikezelo lwe-5V.
• V0 (umahluko): Qhuliswa kwi-potiometer yohlengahlengiso.
• RS (irejista khetha): Khetha irejista yomyalelo okanye irejista yedatha.
• RW (funda / bhala): ilawula indlela yokudluliselwa kwedatha.
• E (Vula): Nifake i-pulse ukuya kwi-latch idatha kwi-LCD.
• I-D0-D7 (idatha): Dlulisa idatha kwi-LCD.

I-PIN ye-PIN ye-PIN inokuhluka kancinci kuxhomekeka kwimodeli ye-LCD. Nxibelelana nedatha ebonelelwe ngumenzi woqwalaselo lwePI oluchanekileyo. Uninzi lwamathala eencwadi ama-microcontrontroller yenza lula inkqubo yokuphumelela. Umzekelo, ithala leencwadi lethala leencwadi le-ballinost e-Arduino lukhetho oludumileyo.

Ukucombulula iingxaki

Nazi ezinye zeengxaki eziqhelekileyo ezidibana nazo xa usebenza kunye I-20x4 LCD Imiboniso kunye nezisombululo zabo:

Izixhobo kunye nokufunda ngakumbi

Ngolwazi olunzulu olunzulu kunye nemizekelo ethile, bhekisa kwiidatha zedatha yomntu ngamnye I-20x4 LCD Iimodeli. Iincwadi ezininzi ze-Intanethi kunye nezixhobo ziyafumaneka, ezinje ngemizobo ye-Arduino kunye namanqaku okusebenzisa abavelisi abahlukeneyo. Ukufumana umgangatho omkhulu I-20x4 LCD IMiboniso kunye nezinye izinto, ziqwalasele ukutyelelwa I-Dalian Mpuma ebonakalayo Co., Ltd. ngokukhetha kwabo iimveliso ze-LCD.

Khumbula ukuhlala ujongane nedatha yedatha yakho I-20x4 LCD imodyuli ye-pinouts echanekileyo kunye neeparamitha ezisebenzayo.
