Waveshare 8inch Capacitive Touch Display ya Raspberry Pi

Zambiri Zamalonda

Zofotokozera

• Dzina la malonda: 8inch DSI LCD
• Mawonekedwe:
  • Mapangidwe a LCD FFC odana ndi kusokoneza ndiwokhazikika pamafakitale.
  • Chithunzi cha VCOMtage kusintha kwa kukhathamiritsa mawonekedwe owonetsera.
  • Kupereka mphamvu kudzera m'mapini a pogo, kuchotsa zingwe zosokoneza.
  • Mitundu iwiri ya mitu yotulutsa 5V, yolumikiza mafani oziziritsa kapena zida zina zotsika mphamvu.
  • Bowo la kamera lotembenuzidwa pagawo lakukhudza limalola kuphatikiza kamera yakunja.
  • Mapangidwe akulu akutsogolo amapangitsa kuti zikhale zosavuta kufananiza milandu yofotokozedwa ndi ogwiritsa ntchito kapena kuphatikizidwa mumitundu yazida.
  • Amatenga mtedza wa SMD kuti ugwire ndikukonza bolodi, mawonekedwe ophatikizika.

Malangizo Ogwiritsira Ntchito Zogulitsa

Kugwira ntchito ndi Raspberry Pi Hardware Connection

1. Gwiritsani ntchito chingwe cha 15PIN FPC kulumikiza mawonekedwe a DSI a 8inch DSI LCD ku mawonekedwe a DSI a Raspberry Pi.
2. Kuti mugwiritse ntchito mosavuta, mutha kulumikiza Raspberry Pi kumbuyo kwa 8-inch DSI LCD yokhazikika ndi zomangira, ndikusonkhanitsa zipilala zamkuwa. (Mawonekedwe a Raspberry Pi GPIO adzapatsa mphamvu LCD kudzera pa pini ya pogo).

Zokonda papulogalamu

Onjezani mizere yotsatirayi ku config.txt file yomwe ili m'mizu ya TF khadi:

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

Yambani pa Raspberry Pi ndikudikirira kwa masekondi angapo mpaka LCD iwonetse bwino. Ntchito yogwira iyeneranso kugwira ntchito pambuyo poyambira.

Backlight Control

Kuwala kwa backlight kumatha kuwongoleredwa ndikulowetsa malamulo otsatirawa mu terminal:

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

Pomwe X imawonetsa nambala iliyonse kuyambira 0 mpaka 255. 0 imatanthauza kuti kuwala kwambuyo ndiko kwakuda kwambiri, ndipo 255 kumatanthauza kuti kuwala kwambuyo ndiko kuwala kwambiri.
Kapenanso, mutha kutsitsa ndikuyika pulogalamu ya Brightness yoperekedwa ndi Waveshare ya Raspberry Pi OS system:

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

Kukhazikitsa kukamaliza, chiwonetsero cha Kuwala chitha kutsegulidwa mu Start Menu -> Chalk -> Kuwala.

Gona

Kuti muyike chophimba mukamagona, yesani lamulo ili pa Raspberry Pi terminal:

xset dpms force off

Letsani Kukhudza

Kuti mulepheretse kugwira ntchito, sinthani config.txt file powonjezera mzere wotsatirawu:

disable_touchscreen=1

Sungani the file ndikuyambitsanso dongosolo kuti zosinthazo zichitike.

Mawu Oyamba

8inch Capacitive Touch Display ya Raspberry Pi, 800 × 480, MIPI DSI Interface

Mawonekedwe

• 8-inch capacitive touch screen yokhala ndi mawonekedwe a Hardware a 800 × 480.
• The capacitive touch panel, imathandizira 5-point touch.
• Magalasi olimba a capacitive touch panel okhala ndi kuuma kwa 6H.
• Imathandizira Pi 4B/3B+/3A+/3B/2B/B+/A+. Chingwe china cha adaputala ndichofunika pa CM3/3+/4a: DSI-Chingwe-15cm.
• Yendetsani molunjika LCD kudzera mu mawonekedwe a DSI a Raspberry Pi, kutsitsimula mpaka 60Hz.
• Imathandizira Raspberry Pi OS / Ubuntu / Kali ndi Retropie ikagwiritsidwa ntchito ndi Raspberry Pi, yopanda galimoto.
• Kuthandizira backlight kusinthidwa ndi mapulogalamu.

Mapangidwe Owonetsedwa

1. Mapangidwe a LCD FFC odana ndi kusokoneza ndiwokhazikika pamafakitale.
2. Chithunzi cha VCOMtage kusintha kwa kukhathamiritsa mawonekedwe owonetsera.
3. Kupereka mphamvu kudzera m'mapini a pogo, kuchotsa zingwe zosokoneza.
4. Mitundu iwiri ya mitu yotulutsa 5V, yolumikiza mafani oziziritsa kapena zida zina zotsika mphamvu.
5. Bowo la kamera lotembenuzidwa pagawo lakukhudza limalola kuphatikiza kamera yakunja.
6. Mapangidwe akulu akutsogolo, amapangitsa kuti zikhale zosavuta kufananiza milandu yofotokozedwa ndi ogwiritsa ntchito kapena kuphatikizidwa mumitundu yazida.
7. Imatengera mtedza wa SMD kuti ugwire ndikukonza bolodi, mawonekedwe ophatikizika

Kugwira ntchito ndi Raspberry Pi

Kulumikizana kwa Hardware

1. Gwiritsani ntchito chingwe cha 15PIN FPC kulumikiza mawonekedwe a DSI a 8inch DSI LCD ku mawonekedwe a DSI a Raspberry Pi.
2. Kuti mugwiritse ntchito mosavuta, mutha kulumikiza Raspberry Pi kumbuyo kwa 8inch DSI LCD yokhazikika ndi zomangira, ndikusonkhanitsa zipilala zamkuwa. (Mawonekedwe a Raspberry Pi GPIO adzapatsa mphamvu LCD kudzera pa pini ya pogo). Mgwirizanowu uli pansipa:

Mapulogalamu a mapulogalamu
Thandizani Raspberry Pi OS / Ubuntu / Kali ndi Retropie machitidwe.

1. Tsitsani chithunzi (Raspbian, Ubuntu, Kali) kuchokera ku Raspberry Pi webmalo.
2. Tsitsani omangika file kwa PC, ndi kutsegula zip kuti mutenge .img file.
3. Lumikizani TF khadi ku PC, ndipo gwiritsani ntchito pulogalamu ya SDFormatter kupanga TF khadi.
4. Tsegulani pulogalamu ya Win32DiskImager, sankhani chithunzi chotsitsidwa pagawo 2, ndikudina 'Lembani' kuti mulembe chithunzi chadongosolo.
5. Mapulogalamu akamaliza, tsegulani config.txt file m'mizu ya TF khadi, onjezani nambala yotsatirayi kumapeto kwa config.txt, sungani ndikuchotsa khadi la TF mosamala.
   dtoverlay=vc4-kms-v3d
   dtoverlay=vc4-kms-dsi-7inch
6. Yambani pa Raspberry Pi ndikudikirira kwa masekondi angapo mpaka LCD iwonetse bwino. Ndipo kugwira ntchito kumatha kugwiranso ntchito dongosolo likayamba.

Backlight Control

• Kuwala kwa backlight kumatha kuwongoleredwa ndikulowetsa malamulo otsatirawa mu terminal:
  echo X> /sys/class/backlight/10-0045/brightness
• Pomwe X ikuwonetsa nambala iliyonse kuyambira 0 mpaka 255. 0 imatanthauza kuti kuwala kwambuyo ndiko mdima kwambiri, ndi
  255 amatanthauza kuti nyali yakumbuyo ndiyo yowala kwambiri. Za exampLe:
  echo 100> /sys/class/backlight/10-0045/brightness
  echo 0> /sys/class/backlight/10-0045/brightness
  echo 255> /sys/class/backlight/10-0045/brightness
• Kuphatikiza apo, Waveshare imapereka ntchito yofananira (yomwe imangopezeka pa
• Raspberry Pi OS system), yomwe ogwiritsa ntchito amatha kutsitsa ndikuyika motere:
  wget https://www.waveshare.com/w/upload/f/f4/Brightness.zip
  tsegulani Brightness.zip
  cd Kuwala
  sudo chmod +x install.sh
  ./install.sh
• Kukhazikitsa kukamaliza, chiwonetserochi chikhoza kutsegulidwa mu Start Menu -> Chalk -> Kuwala, motere:

Gona
Thamangani malamulo otsatirawa pa Raspberry Pi terminal, ndipo chinsalucho chidzalowa m'malo ogona: xset dpms mphamvu

Letsani Kukhudza

Ngati mukufuna kuletsa kugwira ntchito, mutha kusintha config.txt file, onjezani mzere wotsatira ku file ndi kuyambitsanso dongosolo. (Confit file ili m'ndandanda wa mizu ya TF khadi, ndipo imatha kupezekanso kudzera mu lamulo: sudo nano
/boot/config.txt):
disable_touchscreen=1
Zindikirani: Pambuyo powonjezera lamulo, liyenera kuyambiranso kuti ligwire ntchito.
