I-Waveshare 8inch Capacitive Touch Display ye-Raspberry Pi

Ulwazi Lomkhiqizo

Imininingwane

• Igama lomkhiqizo: 8inch DSI LCD
• Izici:
  • Idizayini yekhebula le-LCD ye-FFC yokulwa nokuphazamiseka izinze kakhulu ezinhlelweni zemboni.
  • Ivolumu ye-VCOMtage ukulungiswa kokuthuthukisa umphumela wokubonisa.
  • Ukunikezwa kwamandla ngezikhonkwane ze-pogo, kususa ukuxhunywa kwekhebula okungcolile.
  • Izinhlobo ezimbili zezihloko eziphumayo ze-5V, zokuxhuma abalandeli bokupholisa noma amanye amadivayisi anamandla aphansi.
  • Imbobo yekhamera ehlehlisiwe kuphaneli yokuthinta ivumela ukuhlanganiswa kwekhamera yangaphandle.
  • Idizayini yephaneli enkulu yangaphambili yenza kube lula ukufanisa amakesi achazwe umsebenzisi noma ukuhlanganiswa nezinhlobo zamadivayisi.
  • Yamukela amantongomane e-SMD ukuze abambe futhi alungise ibhodi, isakhiwo esihlangene kakhulu.

Imiyalo yokusetshenziswa komkhiqizo

Ukusebenza nge-Raspberry Pi Hardware Connection

1. Sebenzisa ikhebula le-15PIN FPC ukuze uxhume isixhumi esibonakalayo se-DSI se-8inch DSI LCD kusixhumi esibonakalayo se-DSI se-Raspberry Pi.
2. Ukuze kube lula ukuyisebenzisa, unganamathisela i-Raspberry Pi ngemuva kwe-8-inch DSI LCD ehlanganiswe nezikulufi, futhi uhlanganise izinsika zethusi. (Isixhumi esibonakalayo seRaspberry Pi GPIO sizonika amandla i-LCD ngephinikhodi ye-pogo).

Izilungiselelo Zesofthiwe

Engeza imigqa elandelayo ku-config.txt file itholakala  kumkhombandlela wempande wekhadi le-TF:

dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-7inch

Vula i-Raspberry Pi bese ulinda imizuzwana embalwa kuze kube yilapho i-LCD ibonakala ngokujwayelekile. Umsebenzi wokuthinta kufanele futhi usebenze ngemva kokuqala kwesistimu.

Ukulawula Ukukhanya Kwasemuva

Ukukhanya kwe-backlight kungalawulwa ngokufaka imiyalo elandelayo kutheminali:

echo X > /sys/class/backlight/10-0045/brightness

Lapho u-X ekhomba noma iyiphi inombolo ukusuka ku-0 kuye ku-255. U-0 usho ukuthi ukukhanya kwangemuva kumnyama kakhulu, futhi u-255 usho ukuthi ukukhanya kwangemuva kukhanya kakhulu.
Ngenye indlela, ungalanda futhi ufake uhlelo lokusebenza lokukhanya olunikezwe i-Waveshare yohlelo lwe-Raspberry Pi OS:

wget https://www.waveshare.com/w/upload/f/f4/Brightness.zip
unzip Brightness.zip
cd Brightness
sudo chmod +x install.sh
./install.sh

Uma ukufakwa sekuqediwe, idemo Yokukhanya ingavulwa ku-Start Menu -> Izesekeli -> Ukugqama.

Lala

Ukuze ubeke isikrini kumodi yokulala, sebenzisa umyalo olandelayo  kutheminali ye-Raspberry Pi:

xset dpms force off

Khubaza Ukuthinta

Ukuze ukhubaze umsebenzi wokuthinta, lungisa i-config.txt file ngokungeza umugqa olandelayo:

disable_touchscreen=1

Londoloza i- file bese uqalisa kabusha isistimu ukuze izinguquko zisebenze.

Ukusebenza ne-Raspberry Pi

Ukuxhumeka kwezingxenyekazi zekhompuyutha

1. Sebenzisa ikhebuli engu-15PIN FPC ukuze uxhume isixhumi esibonakalayo se-DSI se-8inch DSI LCD kusixhumi esibonakalayo se-DSI  se-Raspberry Pi.
2. Ukuze kube lula ukuyisebenzisa, unganamathisela i-Raspberry Pi ngemuva kwe-8inch DSI LCD ehlanganiswe ngezikulufo, bese uhlanganisa izinsika zethusi. (Isixhumi esibonakalayo seRaspberry Pi GPIO sizonika amandla i-LCD ngephinikhodi ye-pogo). Ukuxhumana njengoba ngezansi:

Izilungiselelo zesoftware
Sekela iRaspberry Pi OS / Ubuntu / Kali kanye nezinhlelo zeRetropie.

1. Landa isithombe (Raspbian, Ubuntu, Kali) kusuka ku-Raspberry Pi webindawo.
2. Landa okucindezelwe file ku-PC, bese uyivula ukuze uzitholele .img file.
3. Xhuma ikhadi le-TF ku-PC, bese usebenzisa isofthiwe ye-SDFormatter ukufometha ikhadi le-TF.
4. Vula isoftware yeWin32DiskImager, khetha isithombe sohlelo esilandwe esinyathelweni sesi-2, bese uchofoza u-'Bhala' ukuze ubhale isithombe sohlelo.
5. Ngemva kokuphela kokuhlela, vula i-config.txt file kumkhombandlela wezimpande wekhadi le-TF, engeza ikhodi elandelayo ekupheleni kwe-config.txt, londoloza futhi ukhiphe ikhadi le-TF ngokuphepha
   dtoverlay=vc4-kms-v3d
   dtoverlay=vc4-kms-dsi-7inch
6. Vula i-Raspberry Pi bese ulinda imizuzwana embalwa kuze kube yilapho i-LCD ibonakala ngokujwayelekile. Futhi umsebenzi wokuthinta nawo ungasebenza ngemuva kokuqala kwesistimu.

Ukulawula Ukukhanya Kwasemuva

• Ukukhanya kwe-backlight kungalawulwa ngokufaka imiyalo elandelayo kutheminali:
  echo X > /sys/class/backlight/10-0045/brightness
• Lapho u-X ekhombisa noma iyiphi inombolo ukusuka ku-0 kuye ku-255. U-0 usho ukuthi ukukhanya kwangemuva kumnyama kakhulu, futhi
  I-255 isho ukuthi i-backlight ikhanya kakhulu. Okwesiboneloample:
  echo 100 > /sys/class/backlight/10-0045/brightness
  echo 0 > /sys/class/backlight/10-0045/brightness
  echo 255 > /sys/class/backlight/10-0045/brightness
• Ngaphezu kwalokho, i-Waveshare inikeza uhlelo lokusebenza oluhambisanayo (olutholakala kuphela ku-
• Uhlelo lwe-Raspberry Pi OS), abasebenzisi abangalanda futhi balufake ngale ndlela elandelayo:
  wget https://www.waveshare.com/w/upload/f/f4/Brightness.zip
  vula i-Brightness.zip
  cd Ukugqama
  sudo chmod +x install.sh
  ./install.sh
• Uma ukufakwa sekuqediwe, idemo ingavulwa kumenyu yokuqala ->  Izinsiza -> Ukukhanya, kanje:

Lala
Qalisa imiyalo elandelayo kutheminali ye-Raspberry Pi, futhi isikrini sizongena kumodi yokulala: i-xset dpms ivala ngamandla

Khubaza Ukuthinta

Uma ufuna ukukhubaza umsebenzi wokuthinta, ungalungisa i-config.txt file, engeza umugqa olandelayo ku file bese uqalisa kabusha uhlelo. (I-config file itholakala kumkhombandlela wezimpande wekhadi le-TF, futhi ingafinyelelwa ngomyalo: sudo nano
/boot/config.txt):
disable_touchscreen=1
Qaphela: Ngemva kokwengeza umyalo, idinga ukuqaliswa kabusha ukuze isebenze.
