Kev teeb tsa:
Hitachi's HD44780 raws li tus cwj pwm LCD yog pheej yig heev thiab dav, thiab yog ib qho tseem ceeb rau txhua qhov project uas qhia cov ntaub ntawv. Siv lub LCD piggy-rov qab board, cov ntaub ntawv xav tau tuaj yeem tso tawm ntawm LCD los ntawm I2C tsheb npav. Raws li txoj cai, cov hnab ev ntawv no tau tsim nyob ib puag ncig PCF8574 (los ntawm NXP) uas yog lub hom phiaj dav dav bidirectional 8 ntsis I / O chaw nres nkoj nthuav dav uas siv I2C raws tu qauv. PCF8574 yog silicon CMOS Circuit Court muab lub hom phiaj dav dav I/O nthuav dav (ib qho 8-ntsis quasi-bidirectional) rau feem ntau cov tsev neeg microcontroller ntawm ob-kab tsheb npav (I2C-bus). Nco ntsoov tias feem ntau piggy-rov qab modules yog nyob ib ncig ntawm PCF8574T (SO16 pob ntawm PCF8574 hauv DIP16 pob) nrog rau qhov chaw nyob ua qhev ntawm 0x27. Yog tias koj lub rooj tsav xwm piggy-rov qab tuav lub PCF8574AT nti, ces qhov chaw nyob ua qhev yuav hloov mus rau 0x3F. Nyob rau hauv luv luv, yog lub piggy-rov qab board yog raws li PCF8574T thiab qhov chaw nyob txuas (A0-A1-A2) tsis txuas nrog solder nws yuav muaj tus qhev chaw nyob 0x27.
Chaw nyob xaiv pads hauv I2C-rau-LCD piggy-rov qab board.
Chaw Nyob Chaw ntawm PCD8574A (extract los ntawm PCF8574A cov ntaub ntawv specs).
Lus Cim: Thaum lub ncoo A0 ~ A2 qhib, tus pin yog rub mus rau VDD. Thaum tus pin yog solder luv, nws yog rub mus rau VSS.
Lub neej ntawd teeb tsa ntawm qhov module no yog A0 ~ A2 txhua qhov qhib, yog li rub mus rau VDD. Qhov chaw nyob yog 3Fh hauv qhov no.
Daim duab qhia Circuit Court ntawm Arduino-tshaj LCD hnab ev khoom yog qhia hauv qab no. Dab tsi hauv qab no yog cov ntaub ntawv hais txog yuav ua li cas siv ib qho ntawm cov hnab ev khoom pheej yig no los cuam tshuam nrog microcontroller hauv txoj kev uas nws tau npaj tseg.
Daim duab qhia Circuit Court ntawm I2C-rau-LCD piggy-rov qab board.
I2C LCD zaub.
Thaum xub thawj koj yuav tsum tau solder lub I2C-rau-LCD piggy-rov qab board rau 16-pins LCD module. Xyuas kom meej tias I2C-rau-LCD piggy-rov qab board pins yog ncaj thiab haum rau hauv LCD module, ces solder nyob rau hauv thawj tus pin thaum tuav lub I2C-rau-LCD piggy-rov qab board nyob rau hauv tib lub dav hlau nrog lub LCD module. Thaum koj ua tiav cov haujlwm ua haujlwm, tau txais plaub lub xov hlau jumper thiab txuas lub LCD module rau koj Arduino raws li cov lus qhia hauv qab no.
LCD zaub rau Arduino thaiv.
Kev teeb tsa Arduino
Rau qhov kev sim no nws yog qhov tsim nyog los rub tawm thiab nruab "Arduino I2C LCD" tsev qiv ntawv. Ua ntej ntawm tag nrho cov, hloov lub npe "LiquidCrystal" uas twb muaj lawm lub tsev qiv ntawv nplaub tshev nyob rau hauv koj Arduino qiv ntawv tais ceev tseg raws li ib tug thaub qab, thiab mus rau tus so ntawm tus txheej txheem.

Tom ntej no, theej-paste no example sketch Listing-1 rau qhov kev sim rau hauv lub qhov rais dawb paug, txheeb xyuas, thiab tom qab ntawd upload. Arduino Sketch Listing-1:
Yog tias koj 100% paub tseeb tias txhua yam tsis zoo, tab sis koj tsis pom cov cim ntawm cov zaub, sim kho qhov sib piv tswj lub lauj kaub ntawm lub hnab ev ntawv thiab teeb tsa nws txoj haujlwm uas cov cim ci ntsa iab thiab keeb kwm yav dhau tsis muaj qias neeg. cov thawv tom qab cov cim. Hauv qab no yog ib feem view ntawm tus sau qhov kev sim nrog cov lus piav qhia saum toj no nrog 20 × 4 zaub module. Txij li thaum cov zaub siv los ntawm tus sau yog ib qho zoo meej ci "dub rau daj" hom, nws nyuaj heev kom tau txais txiaj ntsig zoo vim muaj teebmeem polarization.
Daim duab kos no tseem yuav tso saib cov cim xa los ntawm serial Monitor:
Hauv Arduino IDE, mus rau "Tools"> "Serial Monitor". Teem tus nqi baud kom raug ntawm 9600. Ntaus tus cim rau saum qhov chaw khoob thiab ntaus "Xa".
Cov hlua ntawm tus cwj pwm yuav tshwm sim ntawm LCD module.
