A: Uninzi lwezibonisi zesangqa zisebenza kumanqanaba e-logic e-3.3V, ngoko ke ukuzidibanisa ngqo kwiibhodi ze-Arduino ze-5V kunokwenzakalisa i-IC yomqhubi. Ii-Logic level shifters, ezaziwa ngokuba zii-voltage dividers, zitshintsha ngokukhuselekileyo imiqondiso phakathi kwemigangatho eyahlukeneyo ye-voltage. Ukuze isebenze ngokuzinzileyo kwaye ihlale ixesha elide, i-GUITION JC2424S012N_I ifuna i-3.3V signaling.

Q: Iphathwa njani inkqubo yokulungelelanisa kuba i-display buffer iyisikwere?

A: Xa i-GC9A01 driver IC ijonga isikrini, iyibona njengegridi ye-240x240 engenamifanekiso kwiikona. I-circular masking ijongwa ngokuzenzekelayo zizixhobo zesoftware, kodwa abaphuhlisi kufuneka basebenzise iindlela ezifanelekileyo zokusika ukuze bagcine izinto ze-UI zingabonakali kwiikona ezingabonakaliyo. Uninzi lweepakethe zemizobo zinomgca wokujonga umda ojikelezayo owakhelwe ngaphakathi.

Q: Yintoni ebangela isikrini esimhlophe okanye ingxolo engashukumiyo kwizibonisi ezijikelezayo?

A: Izikrini ezimhlophe zihlala zithetha ukuba isibane sangasemva sivuliwe, kodwa amanyathelo okuqala asiphumelelanga. Jonga uqhagamshelo lwephini, useto lwemowudi ye-SPI, kunye nexesha elifunekayo ukuqala. Ingxolo engaguqukiyo ingathetha ukuba kukho iingxaki ngoqhagamshelo okanye ngomthombo wamandla. Ukulungisa iimpazamo ngokucwangcisiweyo kuquka ukujonga iiparameter zokuseta ilayibrari, iivoltage zamandla, kunye nokuchaneka kwemiqondiso.

Q: Lingakanani izinga eliphezulu lokuhlaziya elinokufikelelwa ngeArduino?

A: Ngenxa yemida yesantya se-SPI, iibhodi ze-Arduino ezisemgangathweni ze-8-bit (Uno/Nano) zinokufikelela kuphela kumazinga ohlaziyo aphantsi. I-ESP32 kunye nezinye iiplatifomu ze-32-bit ezisebenza ne-Arduino kwaye zivumela i-DMA ukuba zenze isantya sibe ngcono kakhulu. Imodyuli ye-GUITION inokusingatha amaza e-SPI ukuya kuthi ga kwi-40MHz, kodwa amazinga okuhlaziya asetyenzisiweyo aya kuxhomekeka ekubeni zinzima kangakanani na izinto eziboniswayo.

Ngaba ukulungele ukuguqula iiProjekthi zakho zeArduino ngeZiboniso zeLCD ezijikelezileyo zeGuition?

Fumana amava obuchule obutsha obuthenjwe ngamawaka eenjineli kwihlabathi liphela kwiisicelo zabo ze-Arduino zesikrini se-LCD esijikelezayo. I-JC2424S012N_I yeGuition inika ukuthembeka okungenakuthelekiswa nanto nge-IC yayo yomqhubi we-GC9A01 eqinisekisiweyo, ulwakhiwo lomgangatho womkhosi, kunye nenkxaso yophuhliso olupheleleyo. Iqela lethu lobuchwephesha likulungele ukukhawulezisa ixesha leprojekthi yakho ngesikhokelo sobuchwephesha, iiyunithi zesampulu, kunye namaxabiso omthamo afanelekileyo kuhlahlo lwabiwo-mali lwakho. david@guition.com namhlanje ukuze ndifumanise ukuba kutheni abavelisi abaphambili be-LCD Arduino bekhetha iGuition kwiisicelo zabo ezifuna kakhulu.
