I-Handson Technology DSP-1182 I2C Serial Interface 1602 LCD Module User Guide
Lena imojuli ye-I2C yokubonisa i-16 × 2 LCD module, imojuli ye-LCD yezinga eliphezulu engu-2 umugqa wezinhlamvu ezingu-16 enokulungiswa kokulawula umehluko ebhodini, ukukhanya kwangemuva kanye nesixhumi esibonakalayo sokuxhumana se-I2C. Kwabaqalayo be-Arduino, akusekho ukuxhunywa kwesekethe yomshayeli we-LCD onzima futhi oyinkimbinkimbi. Ukubaluleka kwangempela kwe-advantagama-es ale mojula ye-I2C Serial LCD azokwenza lula ukuxhumana kwesekethe, alondoloze izikhonkwane ze-I/O ebhodini le-Arduino, ukuthuthukiswa kwe-firmware okwenziwe lula ngomtapo wezincwadi we-Arduino otholakala kabanzi.
I-SKU: DSP-1182
Idatha emfushane:

Siyalungiselela:
I-LCD ye-HD44780 esekelwe ku-Hitachi ishibhile futhi itholakala kabanzi, futhi iyingxenye ebalulekile yanoma iyiphi iphrojekthi ebonisa ulwazi. Ngokusebenzisa i-LCD piggy-back board, idatha oyifunayo ingavezwa ku-LCD ngebhasi le-I2C. Empeleni, ojosaka abanjalo bakhelwe eduze kwe-PCF8574 (kusuka ku-NXP) okuyinjongo evamile yokwandisa imbobo engu-8 bit I/O esebenzisa iphrothokholi ye-I2C. I-PCF8574 iyisekhethi ye-silicon CMOS ehlinzeka ngezinjongo ezijwayelekile zokunwetshwa kwe-I/O yesilawuli kude (i-8-bit quasi-bidirectional) yemindeni eminingi yama-microcontroller ngebhasi elinemigqa emibili (I2C-bhasi). Qaphela ukuthi amamojula amaningi e-piggy-back agxile ku-PCF8574T (iphakheji ye-SO16 ye-PCF8574 kuphakheji ye-DIP16) enekheli lesigqila elizenzakalelayo elingu-0x27. Uma ibhodi lakho le-piggy-back liphethe chip ye-PCF8574AT, ikheli lesigqila elizenzakalelayo lizoshintsha libe ngu-0x3F. Ngamafuphi, uma ibhodi le-piggy-back lisekelwe ku-PCF8574T futhi ukuxhumeka kwekheli (A0-A1-A2) kungaxhunywanga nge-solder kuzoba nekheli lesigqila elithi 0x27.
Ikheli lokukhetha amaphedi ku-I2C-to-LCD piggy-back board.
Ukusethwa Kwekheli kwe-PCD8574A (ingcaphuno kumininingwane yedatha ye-PCF8574A).
Qaphela: Uma i-pad A0~A2 ivuliwe, iphinikhodi idonselwa ku-VDD. Lapho iphinikhodi ifinyezwa, idonsela phansi ku-VSS.
Ukusetha okuzenzakalelayo kwale mojula kungu-A0~A2 konke kuvuliwe, ngakho-ke ukudonsela phezulu ku-VDD. Ikheli ngu-3Fh kulokhu.
Isethenjwa somdwebo wesikhwama se-LCD esihambisana ne-Arduino siboniswe ngezansi. Okulandelayo ulwazi lokuthi usetshenziswa kanjani omunye walaba ojosaka abangabizi ukuxhumana ne-microcontroller ngezindlela obuhloswe ngazo.
Isethenjwa somjikelezo webhodi le-I2C-to-LCD piggy-back board.
Isibonisi se-I2C LCD.
Ekuqaleni udinga ukudayisa i-I2C-to-LCD piggy-back board kumojula ye-LCD yamaphini angu-16. Qinisekisa ukuthi izikhonkwane ze-I2C-to-LCD piggy-back board ziqondile futhi zilingana kumojuli ye-LCD, bese zithengiswa kuphini lokuqala kuyilapho ugcina ibhodi le-I2C-to-LCD le-piggy-back endizeni efanayo nemojula ye-LCD. Uma usuwuqedile umsebenzi wokuhlanganisa, thola izintambo ezine ze-jumper bese uxhuma imojula ye-LCD ku-Arduino yakho ngokomyalelo onikezwe ngezansi.
Isibonisi se-LCD kuzintambo ze-Arduino.
Ukusethwa kwe-Arduino
Ngalokhu kuhlolwa kuyadingeka ukulanda futhi ufake ilabhulali ye-“Arduino I2C LCD”. Okokuqala, qamba kabusha ifolda yelabhulali ye-“LiquidCrystal” ekhona kufolda yemitapo yolwazi ye-Arduino njengesipele, bese uqhubekela kuyo yonke inqubo.

Okulandelayo, kopisha-namathisele lesi example sketch Listing-1 yokuhlolwa efasiteleni lekhodi elingenalutho, qinisekisa, bese uyalayisha. Uhlu lwe-Arduino Sketch-1:
Uma unesiqiniseko esingu-100% sokuthi konke kuhamba kahle, kodwa ungaziboni izinhlamvu esibonisini, zama ukulungisa ibhodwe lokulawula ukugqama likabhaka bese ulibeka endaweni lapho izinhlamvu zikhanya khona futhi ingemuva lingangcolile. amabhokisi ngemuva kwezinhlamvu. Okulandelayo ingxenye view kokuhlolwa kombhali ngekhodi echazwe ngenhla enemojula yokubonisa engu-20×4. Njengoba isibonisi esisetshenziswe umlobi kuwuhlobo olukhanyayo olucacile "olumnyama kuphuzi", kunzima kakhulu ukuthola ukubamba okuhle ngenxa yemiphumela ye-polarization.
Lo mdwebo uzophinde ubonise ukuthunyelwa kwezinhlamvu kusuka ku-serial Monitor:
Ku-Arduino IDE, iya kokuthi “Amathuluzi"> “Serial Monitor”. Setha izinga elilungile le-baud ku-9600. Thayipha uhlamvu esikhaleni esingenalutho esiphezulu bese ucindezela "THUMELA".
Uchungechunge lohlamvu luzovezwa kumojula ye-LCD.
