Amaphakheji amaningi ehluzo anokuhlolwa komngcele ojikelezayo okwakhelwe ngaphakathi.

Q: Yini ebangela isikrini esimhlophe noma umsindo ongaguquki ezikrinini eziyindilinga?

A: Izikrini ezimhlophe zivame ukusho ukuthi isibani sangemuva sivuliwe, kodwa izinyathelo zokuqala zehlulekile. Hlola ukuxhumeka kwephini, izilungiselelo zemodi ye-SPI, kanye nesikhathi esidingekayo sokuqala. Umsindo oqinile ungasho ukuthi kunezinkinga ngokuxhumeka noma ngomthombo wamandla. Ukulungisa iphutha okuhlelekile kuhlanganisa ukuhlola amapharamitha okusetha umtapo wolwazi, ama-voltage wamandla, kanye nokunemba kwezimpawu.

Q: Yiliphi izinga lokuvuselela eliphezulu kakhulu elingatholakala nge-Arduino?

A: Ngenxa yemikhawulo yesivinini se-SPI, amabhodi ajwayelekile e-Arduino angu-8-bit (Uno/Nano) angafinyelela amazinga okuvuselela aphansi kuphela. I-ESP32 kanye namanye amapulatifomu angu-32-bit asebenza ne-Arduino futhi avumela i-DMA ukuthi yenze isivinini sibe ngcono kakhulu. Imojula ye-GUITION ingaphatha amaza e-SPI afinyelela ku-40MHz, kodwa amazinga okuvuselela asetshenziswayo azoncika ekutheni izinto eziboniswayo ziyinkimbinkimbi kangakanani.

Ukulungele Ukuguqula Amaphrojekthi Akho E-Arduino Ngezibonisi Ze-LCD Eziyindilinga Ze-Guition?

Zizwa izinto ezintsha ezithenjelwa onjiniyela abaningi emhlabeni wonke ngezinhlelo zabo zokusebenza ze-Arduino ezibonisa i-LCD eziyindilinga. I-JC2424S012N_I ye-Guition inikeza ukuthembeka okungenakuqhathaniswa nge-IC yayo yomshayeli we-GC9A01 eqinisekisiwe, ukwakhiwa kwebanga lezempi, kanye nokusekelwa okuphelele kwentuthuko. Ithimba lethu lobuchwepheshe likulungele ukusheshisa isikhathi sephrojekthi yakho ngesiqondiso sochwepheshe, amayunithi esampula, kanye nentengo yevolumu enengqondo ngesabelomali sakho. Xhumana ne-david@guition.com namuhla ukuthola ukuthi kungani abakhiqizi be-Arduino be-LCD abahamba phambili bekhetha i-Guition ngezinhlelo zabo zokusebenza ezidinga kakhulu.
