Fa'atonu:
Hitachi's HD44780 fa'avae amio LCD e matua taugofie ma lautele avanoa, ma o se vaega taua mo so'o se poloketi e fa'aalia fa'amatalaga. I le faʻaaogaina o le LCD piggy-back board, e mafai ona faʻaalia faʻamatalaga manaʻomia ile LCD e ala ile pasi I2C. I le mataupu faavae, o ia ato faafafa e fausia faataamilo i le PCF8574 (mai le NXP) o se faamoemoega lautele bidirectional 8 bit I/O port expander lea e faaaoga le I2C protocol. O le PCF8574 o se kosi CMOS circuit e maua ai le faʻalauteleina o le I/O mamao (o le 8-bit quasi-bidirectional) mo le tele o aiga microcontroller e ala i le pasi lua laina (I2C-bus). Manatua o le tele o mea faʻapipiʻi pito i tua o loʻo faʻatotonugalemu ile PCF8574T (SO16 afifi o le PCF8574 i le DIP16 afifi) faʻatasi ai ma se tuatusi pologa le aoga o le 0x27. Afai o loʻo i ai i lau laupapa pito i tua se pu PCF8574AT, o le a suia le tuatusi pologa i le 0x3F. I se faapuupuuga, afai o le laupapa pito i tua e faʻavae i luga o le PCF8574T ma o fesoʻotaʻiga tuatusi (A0-A1-A2) e le faʻapipiʻiina ma solder o le ai ai le tuatusi pologa 0x27.
Fa'aigoa pepa filifilia i le I2C-to-LCD piggy-back board.
Fa'atulagaina o le tuatusi o le PCD8574A (si'i mai fa'amatalaga fa'amatalaga PCF8574A).
Manatua: A matala le pad A0 ~ A2, e toso le pine ile VDD. A fa'amauina le pine, e toso i lalo i le VSS.
O le fa'aogaina o lenei module o le A0 ~ A2 tatala uma, o lea e toso i luga i le VDD. O le tuatusi e 3Fh i lenei tulaga.
O lo'o fa'aalia i lalo le fa'ata'ita'iga fa'asologa o se ato fa'afafa LCD e fetaui ma Arduino. O le mea o lo'o soso'o mai o fa'amatalaga i le fa'aogaina o se tasi o nei ato fa'afafa taugofie e fa'afeso'ota'i ma se microcontroller i auala na fa'amoemoe tonu ai.
Fa'asinoga fa'ata'amilosaga o le I2C-i-LCD piggy-back board.
I2C LCD fa'aaliga.
I le taimi muamua e te manaʻomia e faʻapipiʻi le I2C-to-LCD piggy-back board i le 16-pins LCD module. Ia fa'amautinoa o lo'o sa'o ma fetaui lelei fa'amau a le I2C-i-LCD i totonu o le LCD module, ona solder lea i le pine muamua a'o tu'u le I2C-to-LCD piggy-back board i le va'alele tutusa ma le LCD module. A mae'a loa le galuega fa'apipi'i, ia maua ni uaea osooso se fa ma fa'afeso'ota'i le module LCD i lau Arduino e pei o le fa'atonuga o lo'o tu'uina atu i lalo.
Fa'aaliga LCD ile Arduino uaea.
Seti Arduino
Mo lenei faʻataʻitaʻiga e manaʻomia le sii mai ma faʻapipiʻi le faletusi "Arduino I2C LCD". Muamua, toe faʻaigoa le faila o loʻo i ai nei "LiquidCrystal" i totonu o lau pusa faletusi Arduino e fai ma faʻamaumauga, ma faʻaauau i le isi vaega o le faagasologa.

Sosoo ai, kopi-pasi le ex leaample sketch Listing-1 mo le faʻataʻitaʻiga i totonu o le faʻamalama avanoa avanoa, faʻamaonia, ona tuʻuina atu lea. Arduino Sketch Listing-1:
Afai e te 100% mautinoa o loʻo lelei mea uma, ae e te le vaʻai i ni mataitusi i luga o le faʻaaliga, taumafai e faʻafetaui le faʻaeseesega faʻatonutonu ulo o le ato faʻafafa ma tuʻu i se tulaga e susulu ai mataʻitusi ma e le palapala le pito i tua. pusa i tua o mataitusi. O lo'o mulimuli mai se vaega view ole fa'ata'ita'iga a le tusitala ile fa'ailoga o lo'o fa'amatalaina ile 20×4 fa'aaliga module. Talu ai o le faʻaaliga na faʻaaogaina e le tusitala o se faʻaaliga manino "uliuli ile samasama", e matua faigata lava ona maua se puʻe lelei ona o aʻafiaga polarization.
O lenei ata o le a faʻaalia ai foʻi uiga lafo mai le Monitor Monitor:
I Arduino IDE, alu i "Meafaigaluega"> "Serial Monitor". Seti le sa'o baud rate i le 9600. Fa'apipi'i le tagata i le pito i luga avanoa avanoa ma ta "SEND".
O le manoa o uiga o le a faʻaalia i luga o le LCD module.
