Imiyalelo yokusetyenziswa kwemveliso

Ukusebenza kunye neRaspberry Pi Hardware Connection

1. Sebenzisa intambo ye-15PIN ye-FPC ukudibanisa i-DSI interface ye-8inch DSI LCD kwi-interface ye-DSI ye-Raspberry Pi.
2. Ukusebenziseka lula, unokuqhoboshela i-Raspberry Pi ngasemva kwe-8-intshi ye-DSI LCD elungiswe ngezikrufu, kwaye uhlanganise iintsika zobhedu. (Ujongano lweRaspberry Pi GPIO luya kunika amandla iLCD ngepini yepogo).

Izicwangciso zeSoftware

Yongeza le migca ilandelayo kwi-config.txt file ibekwe kuluhlu lweengcambu zekhadi leTF:

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

Amandla kwiRaspberry Pi kwaye ulinde imizuzwana embalwa de i-LCD ibonise ngokuqhelekileyo. Umsebenzi wokuchukumisa kufuneka usebenze emva kokuba inkqubo iqalile.

Ulawulo lwesibane ngasemva

Ukukhanya kwesibane esingasemva kunokulawulwa ngokungenisa le miyalelo ilandelayo kwi-terminal:

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

Apho u-X abonisa naliphi na inani ukusuka ku-0 ukuya ku-255. U-0 uthetha ukuba isibane esingasemva sesona simnyama, kwaye u-255 uthetha ukuba isibane sangasemva sesona siqaqambile.
Kungenjalo, unokukhuphela kwaye ufake isicelo soBukhanye esibonelelwe yiWaveshare yeRaspberry Pi OS inkqubo:

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

Nje ukuba ufakelo lugqityiwe, idemo yokuKhanya inokuvulwa kwiMenu yokuQala -> Izixhobo -> Ukuqaqamba.

Lala

Ukubeka isikrini kwimo yokulala, sebenzisa lo myalelo ulandelayo kwi-terminal yeRaspberry Pi:

xset dpms force off

Khubaza ukubamba

Ukuyekisa umsebenzi wokuchukumisa, guqula kancinane i-config.txt file ngokongeza lo mgca ulandelayo:

disable_touchscreen=1

Gcina i file kwaye uqalise kwakhona inkqubo ukuze utshintsho lusebenze.

FAQ
