Lesi sikhala sigcwaliswa ngabaphakeli abanjengoGuition, abanikeza ukwenza ngokwezifiso okuningi ngenkathi besanikeza usizo oluqinile lochwepheshe kanye nemibhalo enemininingwane.

Ama-OEM angayithuthukisa kanjani ukusetshenziswa kwamandla kumamojula okubonisa?

Sebenzisa amasu okukhanya okuguquguqukayo ukushintsha amandla okukhanyisa kwangemuva ngokusekelwe ezibanini ezizungeze idivayisi. Vumela izindlela zokulala zezibonisi uma zingasetshenziswa, kodwa lungisa isikhathi sokuvuka ukuze uhlangabezane nezidingo zezinhlelo zokusebenza ezidinga ukuphendula ngokushesha. Bheka ubuchwepheshe obuhlukene besikrini. I-OLED isebenza kahle kakhulu ngezixhumi ezimnyama, kuyilapho i-LCD isebenza kangcono ngezinto ezikhanyayo. Khuluma nemithombo yakho mayelana nokuthola abashayeli be-LED nama-IC okulawula amandla asebenza kahle ngemigqa yakho ye-voltage kanye nemikhawulo yamanje.

Yiziphi izikhathi ezijwayelekile zokuhola zama-oda okwenza ngokwezifiso ngobuningi?

Ungalindela amasonto ayi-8 kuya kwayi-12 kusukela ngesikhathi uvuma imininingwane uze uthole isampula yokuqala yemojuli eguquliwe kahle. Izikhathi zingase zihlehliswe ziye emavikini ayi-14 kuya kwayi-16 uma kunezinguquko eziyinkimbinkimbi zobunjiniyela noma izidingo zokuxhumana ezikhethekile. Ngokuthengisa okukhulu, ukwanda kokukhiqiza kuthatha amasonto ama-4 kuya kwayi-6 engeziwe ngaphambi kokuqala kokuthunyelwa okuvamile. Hlala uthintana nemithombo yakho kuyo yonke inqubo yokuthuthukisa ukuze ukwazi ukubona noma yikuphi ukubambezeleka okungenzeka kusenesikhathi futhi wenze izinguquko ohlelweni lwakho lwephrojekthi njengoba kudingeka.

Bambisana Nesiqondisi Sezixazululo Zokubonisa Eziphezulu

I-Guition yenza amaphaneli okubonisa e-HMI obuchwepheshe obuphezulu aklanyelwe ukusebenza ngokusetshenziswa kwe-OEM okunzima kumadivayisi ezokwelapha, izinhlelo ze-IoT ezihlakaniphile, kanye nokwenza izinto ngokuzenzakalela kwezimboni. Le module ye-JC-ESP32P4-M3-DEV inawo womabili ama-chipset e-ESP32P4 kanye ne-ESP32-C6 akhelwe ngaphakathi. Inamandla okucubungula e-RISC-V angu-400MHz futhi ingaxhuma ku-Wi-Fi 6 kanye ne-Bluetooth 5. Izixhumi eziningi ziyasekelwa, njenge-MIPI-CSI, i-MIPI-DSI, kanye ne-USB 2.0 OTG, ngakho-ke isebenza kahle ngemiklamo eminingi ehlukene yehadiwe. Isofthiwe yokuthuthukisa i-Guition ehlukile yenza kube lula ukwenza ama-UI ngokusebenzisa izilawuli ezilula zokudonsa nokulahla. Iphinde isekele izindlela zokuthuthukisa ze-Arduino, IDF, kanye nezindlela zokuthuthukisa zendabuko futhi isusa isidingo sekhodi eyinkimbinkimbi yezinga eliphansi. Ukusekelwa kwezilimi eziningi kanye nekhono lokubuyekeza kude ukunciphisa izindleko zokulungisa nokwenza kube nokwenzeka ukwamukelwa komhlaba wonke. Xhumana ne-david@guition.com ngokushesha ukuze uxoxe ngezidingo zakho nethimba lethu lobunjiniyela futhi uthole ukuthi ulwazi lwethu njengomthengisi we -Raspberry Pi display module lungakusiza kanjani ukusheshisa intuthuko yomkhiqizo wakho ngenkathi ugcina ubuhle bezobuchwepheshe.
