Fa'amatalaga o oloa

Fa'amatalaga

  • Igoa oloa: 8inch DSI LCD
  • Vaega:
    • O le LCD FFC cable anti-interference design e sili atu ona mautu mo talosaga tau alamanuia.
    • VCOM voltagu fetuutuunaiga mo le fa'amalieina o fa'aaliga fa'aaliga.
    • Tuuina atu o le eletise e ala i pine pogo, faʻaumatia fesoʻotaʻiga uaea leaga.
    • E lua ituaiga o ulutala 5V, mo le faʻafesoʻotaʻi o tagata faʻamafanafana poʻo isi masini maualalo.
    • O le pu o meapueata liliu i luga o le laulau pa'i e mafai ai ona tu'ufa'atasia meapueata fafo.
    • O le mamanu pito i luma lapopoa e faigofie ai ona faʻafetaui mataupu faʻamalamalamaina e le tagata poʻo le tuʻufaʻatasia i ituaiga masini.
    • Faʻaaogaina nati SMD mo le uuina ma le faʻapipiʻiina o le laupapa, o se fausaga sili atu ona laititi.

Fa'atonuga o le Fa'aaogaina o Mea

Galulue ma Raspberry Pi Hardware Connection

  1. Fa'aaoga le 15PIN FPC cable e fa'afeso'ota'i le DSI interface o le 8inch DSI LCD i le DSI interface o le Raspberry Pi.
  2. Mo le faigofie o le faʻaoga, e mafai ona e faʻapipiʻi le Raspberry Pi i le pito i tua o le 8-inisi DSI LCD faʻapipiʻi ma sikulima, ma faʻapipiʻi pou kopa. (O le Raspberry Pi GPIO interface o le a faʻamalosia le LCD e ala i le pine pogo).

Fa'atonuga polokalame

Fa'aopoopo laina nei ile config.txt file o loʻo i totonu o le lisi autu o le TF card:

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

Malosi i luga ole Raspberry Pi ma fa'atali mo ni nai sekone se'ia fa'aalia masani le LCD. E tatau foi ona galue le galuega pa'i pe a uma ona amata le faiga.

Pulea o le moli tua

E mafai ona pulea le susulu o le backlight e ala i le tuʻuina atu o tulafono nei i le laina:

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

A fa'ailoa mai e X so'o se numera mai le 0 i le 255. 0 o lona uiga o le moli pito i tua e sili ona pogisa, ma le 255 o lona uiga o le moli tua e sili ona susulu.
I le isi itu, e mafai ona e sii mai ma faʻapipiʻi le Brightness application na saunia e Waveshare mo le 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

A maeʻa le faʻapipiʻiina, e mafai ona tatalaina le faʻaaliga Brightness i le Amata Menu -> Faʻaoga -> Malamalama.

Moe

Ina ia tuʻu le lau i le moe moe, faʻataʻitaʻi le poloaiga lenei i luga o le Raspberry Pi terminal:

xset dpms force off

Taofi le Pa'i

Ina ia tape le galuega pa'i, sui le config.txt file e ala i le fa'aopoopoina o le laina lea:

disable_touchscreen=1

Faasaoina le file ma toe fa'afou le faiga mo suiga ina ia aoga.
