Imiyalo yokusetshenziswa komkhiqizo

I-Hardware Connection

• Xhuma isixhumi esibonakalayo se-DSI se-4.3-inch DSI LCD kusixhumi esibonakalayo se-DSI se-Raspberry Pi. Ukuze uyisebenzise kalula, ungalungisa i-Raspberry Pi ngemuva kwe-4.3-inch DSI LCD usebenzisa izikulufu.

Ukusetha Isofthiwe

• Engeza imigqa elandelayo ku-config.txt file:dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-7inch

• Faka amandla ku-Raspberry Pi bese ulinda imizuzwana embalwa kuze kube ama-LCDs ajwayelekile. Umsebenzi wokuthinta uzophinde usebenze ngemuva kokuqala kwesistimu.

Ukulawula Ukukhanya Kwasemuva

• Ukuze ulungise ukukhanya, vula itheminali bese uthayipha umyalo olandelayo:echo X > /sys/class/backlight/rpi_backlight/brightness

• Miselela u-X ngevelu kububanzi obungu-0 kuye ku-255. Ukukhanya kwangemuva kumnyama kakhulu kokuthi 0 futhi kukhanye kakhulu kokuthi 255.
• Exampngiyala:echo 100 > /sys/class/backlight/rpi_backlight/brightness echo 0 > /sys/class/backlight/rpi_backlight/brightness echo 255 > /sys/class/backlight/rpi_backlight/brightness

• Ungakwazi futhi ukulanda futhi ufake isofthiwe yokulungisa ukukhanya usebenzisa le miyalo elandelayo: wget https://www.com.waveshare.net/w/upload/3/39/Brightness.tar.gztar-xzf-Brightness.tar.gzcd brightness.install.sh

• Ngemva kokufaka, iya kokuthi Imenyu -> Izesekeli -> Ukukhanya ukuze uvule isofthiwe yokulungisa.
• Qaphela: Uma usebenzisa isithombe se-2021-10-30-raspios-bullseye-armhf noma inguqulo yakamuva, engeza umugqa "dtoverlay=rpi-backlight" ku-config.txt file bese uqalisa kabusha.

Imodi yokulala

• Ukufaka isikrini kumodi yokulala, sebenzisa umyalo olandelayo kutheminali ye-Raspberry Pi: xset dpms force off


Khubaza Ukuthinta

• Ukuze ukhubaze ukuthinta, engeza umyalo olandelayo ekugcineni kwe-config.txt file: sudo apt-get install matchbox-keyboard

• Qaphela: Ngemva kokwengeza umyalo, qala kabusha uhlelo ukuze lusebenze.

Ukulawula Ukukhanya Kwasemuva

• Vula itheminali bese uthayipha umyalo olandelayo ukuze ulungise ukukhanya.
• Qaphela: Uma umyalo ubika iphutha elithi ‘Imvume inqatshelwe’, sicela ushintshele kumodi yomsebenzisi ‘impande’ bese ulenza futhi.
• U-X angaba inani kububanzi obungu-0~255. Ilambu elingemuva limnyama kakhulu uma ukusethela ku-0 futhi i-backlight isethwe ukuthi ikhanye kakhulu uma ukusethe ku-255
• Siphinde sinikeze i-example ngokulungiswa kokukhanya, ungalanda futhi ukufake ngokulandela imiyalo:
• Ngemva kokuxhuma, ungakhetha Imenu -> Izesekeli -> Ukukhanya ukuze uvule isofthiwe yokulungisa
• Qaphela: Uma usebenzisa isithombe se-2021-10-30-raspios-bullseye-armhf noma inguqulo yakamuva, sicela wengeze umugqa othi dtoverlay=rpi-backlight ku-config.txt file bese uqalisa kabusha.

Lala

I-Anti-Piracy

• Selokhu kwakhululwa i-Raspberry Pi yesizukulwane sokuqala, i-Waveshare ibisebenzela ukuklama, ukuthuthukisa, nokukhiqiza ama-LCD wokuthinta ahlukahlukene we-Pi. Ngeshwa, kunemikhiqizo embalwa ephihliwe/ekhishwa emakethe.
• Ngokuvamile zingamakhophi ampofu ezibuyekezo zethu zezingxenyekazi zekhompuyutha zangaphambi kwesikhathi futhi azizi nesevisi yosekelo.
• Ukuze ugweme ukuba yisisulu semikhiqizo yobugebengu, sicela unake izici ezilandelayo lapho uthenga:
• (Chofoza ukuze ukhulise)

Qaphela ama-knock-offs

• Sicela uqaphele ukuthi sithole amakhophi ampofu ale nto emakethe. Ngokuvamile zenziwe ngezinto ezisezingeni eliphansi futhi zithunyelwa ngaphandle kokuhlolwa.
• Kungenzeka uyazibuza ukuthi le oyibukile noma oyithenge kwezinye izitolo ezingekho emthethweni ingeyokuqala, zizwe ukhululekile ukusithinta.

Ukusekela

• Uma udinga ukwesekwa kobuchwepheshe, sicela uye ekhasini bese uvule ithikithi.
