Banikezela ngendlela enengqondo yokusebenzisana nenkqubo kwaye balungele iiprojekthi ezizenzekelayo, iinkqubo ze-kiosk, okanye ukuphucula amava omsebenzisi. Nangona kunjalo, ukuseta ngokuchanekileyo kwiRaspberry Pi OS kunokuba ngumngeni, ngakumbi ngaphandle kwesikhokelo esicacileyo nesicacileyo.
Kweli nqaku, uya kufumana lonke ulwazi oludingayo ukuze uqonde indlela i-capacitive touchscreens esebenza ngayo, amanyathelo okufaka ngokufanelekileyo kwaye uwaqwalasele, kunye nezisombululo kwiingxaki eziqhelekileyo ezinokuvela ngexesha lokusetyenziswa. Siza kuphonononga izicelo ezahlukeneyo zokukunceda ufumane okuninzi kwiscreen sakho sokuchukumisa iRaspberry Pi.
Yintoni isikrini esichukumisayo esinamandla?
I-Capacitive touch screens luhlobo lwesikrini esibona umfowunelwa usebenzisa i-touchpad. iimpawu zombane zomzimba womntu. Ngokungafani nezikrini ezichasayo, ezifuna uxinzelelo lokubhalisa ukusebenzisana, izikrini ze-capacitive zisabela ngokuchukumisa. ukubamba okulula kweminwe. Oku kuvumela amava alula kunye nokukwazi ukusebenzisa izijekulo ezininzi zokuchukumisa.
Iimpawu zecapacitive touchscreens zeRaspberry Pi
- Multi-touch inkxaso: Uninzi lwezi zikrini zivumela unxibelelwano kunye iminwe emininzi.
- Isisombululo esiphezulu: Iimodeli ezifana nescreen se-intshi ezisi-7 zihlala zibonelela ngezigqibo zokuya kuthi ga Iiphikseli ezingama-1024 × 600.
- Ukuhambelana kweRaspberry Pi: Yenzelwe ukudibanisa ngokulula nge HDMI okanye DSI.
- Ukuzinza: Ziyakwazi ukumelana nokunxiba xa kuthelekiswa nezikrini ezichasayo.
Izinto ezifunekayo ukufaka isikrini sokuchukumisa kwiRaspberry Pi
Ngaphambi kokuba uqalise ukufakela, qiniseka ukuba unayo amalungu alandelayo:
- Raspberry Pi (HDMI okanye DSI imifuziselo ehambelanayo).
- Capacitive touch screen.
- Intambo yeHDMI okanye yeDSI yoqhagamshelwano.
- Unikezelo lwamandla kwiRaspberry Pi.
- Ikhadi leMicroSD elineRaspberry Pi OS efakiweyo.
- Iintambo zoqhagamshelwano (ukuba kuyimfuneko).
Indlela yokufaka kunye nokuqwalasela isikrini sokuchukumisa kwiRaspberry Pi
1. Qhagamshela umboniso kwiRaspberry Pi
Ngokuxhomekeke kuhlobo lwesikrini onalo, uqhagamshelo lunokwenziwa ngokusebenzisa intambo ye-HDMI okanye nge Izibuko leRaspberry Pi DSI:
- Kwimiboniso ye-HDMI: Qhagamshela kwizibuko le-HDMI kwiRaspberry Pi kwaye uqinisekise ukuba ibotshelelwe ngokukhuselekileyo.
- Kwimiboniso yeDSI: Sebenzisa intambo yeDSI kwaye uyidibanise kwizibuko elihambelanayo kwiRaspberry Pi.
2. Vula inkqubo kwaye uqinisekise ubhaqo
Qhagamshela unikezelo lwamandla kwaye uvule iRaspberry Pi. Ukuba yonke into idityaniswe ngokuchanekileyo, Isikrini kufuneka sivule kwaye sibonise inkqubo yokusebenza.
3. Seta ukuqhelaniswa nesikrini
Ukuba umfanekiso ubonakala ujikelezisiwe, unako tshintsha useto ukuhlela ifayile / i / boot /config.txt kwaye wongeza umgca ofanelekileyo:
- 90 degree rotation:
display_rotate=1 - 180 degree rotation:
display_rotate=2 - 270 degree rotation:
display_rotate=3
Gcina utshintsho kwaye uqalise kwakhona iRaspberry Pi.
4. Faka abaqhubi besikrini sokuchukumisa
Ezinye izikrini zifuna abaqhubi abongezelelweyo ukuba isikrini sokuchukumisa sisebenze kakuhle. Ukuzifaka, landela imiyalelo yomenzi okanye ujonge ukuba ziyahambelana neRaspberry Pi OS kwizikhokelo ezifana Esi sikhokelo kwizikrini zokuchukumisa.
5. Linganisa isikrini sokuchukumisa
Ukuba isikrini sokuchukumisa asiphenduli ngokuchanekileyo, kunokuba njalo kufuneka ilinganiswe. Ukwenza oku, unokufaka izixhobo ezinje:
sudo apt install xinput-calibratorQhuba ulungelelwaniso kwaye ulandele i imiyalelo yesikrini.
6. Vula ikhibhodi enenyani
Ukuba awunayo ikhibhodi ebonakalayo eqhagamshelwe, ungasebenzisa ikhibhodi ekwisikrini ngokuhlohla:
sudo apt install matchbox-keyboardXa sele ifakiwe, Ungayivula kwimenyu yofikelelo.
Isisombululo kwiingxaki eziqhelekileyo
Isikrini asivulwa
- Qinisekisa oko zonke iintambo ziqhagamshelwe ngokufanelekileyo.
- Qiniseka ukuba unikezelo lwamandla lwanele.
- Zama enye bonisa okanye i-HDMI port.
Isikrini esichukumisayo asiphenduli
- Khangela ukuba ufuna abaqhubi abongezelelweyo.
- Qiniseka ukuba iintambo zedatha ziqhagamshelwe ngokufanelekileyo.
- Qhuba ulungelelwaniso nge
xinput-calibrator.
Umfanekiso ubonakala ugqwethiwe okanye udanyaza
- Sebenzisa a umgangatho olungileyo HDMI cable.
- Lungisa useto lwe isisombululo kwifayile /boot/config.txt.
- Zama enye unikezelo lwamandla olunamandla ngakumbi.
Usetyenziso kunye nokusetyenziswa kwezikrini zokuchukumisa kwiRaspberry Pi
- Iziko lemultimedia: Sebenzisa iinkqubo ezifana ne-Kodi ukujonga umxholo kujongano lokuchukumisa.
- Ukuzenzekela eKhaya: Izibane zokulawula kunye nezixhobo ezihlakaniphile ukusuka kujongano olubonakalayo.
- I-interactive kiosks: Yenza iiphaneli zolwazi okanye iindawo zokuthengisa ezisebenzisanayo, njengoko usenza ku iinkqubo zekiosk.
- Iimpawu zomdlalo weRetro: Dlala iiklasikhi kunye nojongano oluphuculweyo lokuchukumisa.
Izikrini zokuchukumisa zeRaspberry Pi zibonelela ngendlela enomtsalane nesebenzayo yokuphucula amava omsebenzisi kwiiprojekthi zazo zonke iintlobo. Ukuzicwangcisa ngokuchanekileyo kunokufuna amanyathelo ongezelelweyo ambalwa, kodwa esi sikhokelo siya kukunika lonke ulwazi oludingayo ukuze ukwenze ngaphandle kokuphazamiseka. Nokuba uyisebenzisela ukudlala, ukuzenzela, okanye ukusebenzisana ngokukhululekileyo neRaspberry Pi, ezi zibonisi zibonelela. ukuguquguquka okukhulu kunye nokusebenza.
