Ntuziaka ojiji ngwaahịa

Na-arụ ọrụ na njikọ Raspberry Pi Hardware

1. Jiri eriri FPC 15PIN jikọọ interface DSI nke 8inch DSI LCD na interface DSI nke Raspberry Pi.
2. Maka ịdị mfe iji, ị nwere ike itinye Raspberry Pi n'azụ 8-inch DSI LCD nke ejiri skru dozie ya, wee kpokọta ogidi ọla kọpa. (Ntugharị Raspberry Pi GPIO ga-enye ike LCD site na pin pogo).

Ntọala ngwanrọ

Tinye ahịrị ndị a na config.txt file dị na ndekọ mgbọrọgwụ nke kaadị TF:

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

Ike na Raspberry Pi wee chere sekọnd ole na ole ruo mgbe ngosi LCD na-adịkarị. Ọrụ mmetụ ahụ kwesịkwara ịrụ ọrụ mgbe usoro ahụ malitechara.

Njikwa ọkụ azụ

Enwere ike ịchịkwa nchapụta azụ azụ site na itinye iwu ndị a na njedebe:

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

Ebe X na-egosi ọnụọgụ ọ bụla site na 0 ruo 255. 0 pụtara ìhè azụ bụ nke kacha gbaa ọchịchịrị, na 255 pụtara ìhè azụ bụ nke kacha egbuke egbuke.
N'aka nke ọzọ, ịnwere ike ibudata ma wụnye ngwa ihie nke Waveshare nyere maka sistemụ Raspberry Pi:

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

Ozugbo echichi mechara, enwere ike imeghe ngosi ihie na mbido NchNhr -> Ngwa -> ihie.
