Kuv yuav Waveshare E-Paper 1.54 rau qhov haujlwm sib txawv li no.. ntawm no yog phau ntawv qhia yuav ua li cas rau nruab nws
Kauj Ruam 1: Daim Ntawv Teev Npe
Nov yog yam koj yuav xav tau:
- ib Raspberry pi 3
- lub tshuab nyob deb rau SSH rau pi lossis lub vijtsam thiab keyboard los txuas rau nws ncaj qha
- WaveShare E-paper module 1.54 (qauv A)
Kauj Ruam 2: Txuas nrog PI
Ua raws li lub npe cable thiab daim duab thaum txuas lub vijtsam rau Raspberry pi IO
Kauj ruam 3: Rub tawm thiab Nruab Qiv
Kuv tau ntxiv cov tsev qiv ntawv rub tawm cov ntaub ntawv rau txoj haujlwm, thawj qhov txuas hauv qab no

Kev teeb tsa
Nkag mus rau WiringPi nplaub tshev, tom qab ntawv ua raws cov lus txib no rau nruab:
chmod 777 ua
./ tsim
kos lub installation nrog:
gpio vwm
Mus rau bcm2835 cov tsev qiv ntawv cov ntawv tais ceev tseg, tom qab ntawv ua raws cov lus txib no rau nruab:
./configuremake sudo ua kos sudo ua nruab
Download tau tus lej demo
rov ua cov ntaub ntawv hauv bcm2835 thiab wiringpi nplaub tshev los ntawm kev mus rau daim nplaub tshev thiab ua
cd PATH/OF/DEMO/FOLDER/Rasberry/bcm2835 ua kom huv
cd PATH/OF/DEMO/FOLDER/Rasberry/wiringpi
ua kom huv
ua
Kauj Ruam 4: Hloov Kho Koj Tus Kheej
Ua ntej koj tuaj yeem khiav cov cai koj yuav tsum hloov pauv me me.
Txoj cai siv tus ntawv tsis yog nyob rau ntawm Rasbien instell yog li hloov hom font
font = ImageFont.truetype ('/usr/share/fonts/truetype/wqy/wqy-microhei.ttc', 24)
rau lwm qhov font uas muaj nyob hauv koj lub cev.
kos muaj font los ntawm kev ua thiab hloov qhov tshwm sim, kuv tau hloov nws mus
ls/usr/qhia tawm/fonts/truetype/
font = ImageFont.truetype ('/usr/qhia tawm/fonts/truetype/freefont/FreeSansBold.ttf', 24)
hauv main.py
duab = Image.open ('dawb-rick-tsim-700x700.bmp')
epd.display (epd.getbuffer (duab))
sijhawm.sleep (2)
Kauj ruam 5: Hloov Demo Code
Los ntawm Cov piv txwv cov ntaub ntawv hauv qhov demo ntawm no yog qee qhov lus txib koj tuaj yeem siv sab hauv koj tus kheej cov ntawv sau se
ntshuam lub nruab interface
ntshuam epd1in54 los ntawm PIL ntshuam duab, ImageDraw, ImageFont
Pib qhov Screen
epd = epd1in54. EPD ()
epd.init (epd.lut_full_update) epd. Clear (0xFF)
Qhib thiab Tso duab
duab = Duab.open ('1in54.bmp') epd.display (epd.getbuffer (duab))
