Umarnin Amfani da samfur

Yin aiki tare da Haɗin Rasberi Pi Hardware

1. Yi amfani da kebul na FPC 15PIN don haɗa haɗin haɗin DSI na 8inch DSI LCD zuwa ƙirar DSI na Rasberi Pi.
2. Don sauƙin amfani, zaku iya haɗa Rasberi Pi zuwa baya na 8-inch DSI LCD da aka gyara tare da sukurori, kuma ku haɗa ginshiƙan tagulla. (Maganin Rasberi Pi GPIO zai yi amfani da LCD ta hanyar fil ɗin pogo).

Saitunan software

Ƙara layin masu zuwa zuwa config.txt file dake cikin tushen tushen katin TF:

Ƙaddamar da Rasberi Pi kuma jira na ɗan daƙiƙa har sai LCD ya nuna kullum. Hakanan aikin taɓawa yakamata yayi aiki bayan an fara tsarin.

Ikon Hasken Baya

Ana iya sarrafa hasken baya ta hanyar shigar da umarni masu zuwa a cikin tasha:

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

Inda X ke nuna kowane lamba daga 0 zuwa 255. 0 yana nufin hasken baya shine mafi duhu, kuma 255 yana nufin hasken baya shine mafi haske.
A madadin, zaku iya saukewa kuma shigar da aikace-aikacen Brightness wanda Waveshare ya bayar don tsarin Rasberi 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

Da zarar an gama shigarwa, za a iya buɗe nunin haske a cikin Fara Menu -> Na'urorin haɗi -> Haske.

Kashe Taɓa

Don kashe aikin taɓawa, gyara config.txt file ta hanyar ƙara layi mai zuwa:
