  • Moralo o khahlano le tšitiso ea LCD FFC o tsitsitse haholoanyane lits'ebetsong tsa indasteri.
  • Phaello ea VCOMtage tokiso bakeng sa ho ntlafatsa phello ea ponts'o.
  • Phepelo ea motlakase ka lithapo tsa pogo, e felisang likhokahano tse bohlasoa tsa lithapo.
  • Mefuta e 'meli ea lihlooho tsa tlhahiso ea 5V, bakeng sa ho hokahanya li-fan tse pholileng kapa lisebelisoa tse ling tse tlaase.
  • Lesoba la kh'amera le khutlisitsoeng holim'a phanele ea ho ama le lumella kh'amera ea kantle ho kopanya.
  • Moralo o moholo oa liphanele tse ka pele o etsa hore ho be bonolo ho bapisa linyeoe tse hlalositsoeng ke basebelisi kapa ho kopanngoa le mefuta ea lisebelisoa.
  • E amohela linate tsa SMD bakeng sa ho ts'oara le ho lokisa boto, sebopeho se kopaneng haholoanyane.

Litaelo tsa Tšebeliso ea Sehlahisoa

Ho sebetsa le Raspberry Pi Hardware Connection

1. Sebelisa thapo ea 15PIN FPC ho hokela sebopeho sa DSI sa 8inch DSI LCD ho sebopeho sa DSI sa Raspberry Pi.
2. Bakeng sa tšebeliso e bonolo, o ka hokela Raspberry Pi ka morao ho 8-inch DSI LCD e kentsoeng ka li-screws, 'me u kopanya litšiea tsa koporo. (Sebopeho sa Raspberry Pi GPIO se tla matlafatsa LCD ka pini ea pogo).

Lisebelisoa tsa Software

Kenya mela e latelang ho config.txt file e fumanehang bukeng ea motso ea karete ea TF:

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

Matla ho Raspberry Pi 'me u eme metsotsoana e seng mekae ho fihlela LCD e bontša ka tloaelo. Mosebetsi oa ho ama o boetse o lokela ho sebetsa ka mor'a hore tsamaiso e qale.

Backlight Control

Khanya ea backlight e ka laoloa ka ho kenya litaelo tse latelang ho terminal:

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

Moo X e bonts'ang nomoro efe kapa efe ho tloha ho 0 ho isa ho 255. 0 e bolela hore lebone la morao ke le lefifi ka ho fetisisa, 'me 255 e bolela hore lebone la morao ke lona le khanyang ka ho fetisisa.
Ntle le moo, o ka khoasolla le ho kenya sesebelisoa sa Brightness se fanoeng ke Waveshare bakeng sa sistimi ea 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

Hang ha ts'ebetso e felile, demo ea Brightness e ka buloa ho Start Menu -> Lisebelisoa -> Khanya.

Robala

Ho beha skrine ka mokhoa oa ho robala, tsamaisa taelo e latelang ho terminal ea Raspberry Pi:

xset dpms force off

Thibela ho ama

Ho thibela tšebetso ea ho ama, fetola config.txt file ka ho eketsa mola o latelang:

disable_touchscreen=1

Boloka the file ebe o qala sistimi hape hore liphetoho li sebetse.
