WHADDA WPI438 0.96Inch OLED Screen yokhala ndi I2C ya Arduino

Mawu Oyamba

Kwa onse okhala mu European Union
Zofunikira zachilengedwe zokhudzana ndi mankhwalawa

Chizindikiro ichi pa chipangizocho kapena phukusili chikuwonetsa kuti kutaya kwa chipangizocho pambuyo pa moyo wake kumatha kuwononga chilengedwe. Osataya unit (kapena mabatire) ngati zinyalala zamatauni zomwe sizinasankhidwe; ziyenera kutengedwa ku kampani yapadera kuti zibwezeretsedwe. Chipangizochi chiyenera kubwezeredwa kwa wogawa wanu kapena kuntchito yobwezeretsanso. Lemekezani malamulo a chilengedwe.
Ngati mukukayika, funsani akuluakulu otaya zinyalala m'dera lanu.

Zikomo posankha Velleman®! Chonde werengani bukuli musanatenge chida ichi. Ngati chipangizocho chidawonongeka popita, osayiyika kapena kuyigwiritsa ntchito ndipo kambiranani ndi ogulitsa anu.

Malangizo a Chitetezo

• Chipangizochi chitha kugwiritsidwa ntchito ndi ana azaka zoyambira 8 ndi kupitilira apo, komanso anthu omwe ali ndi mphamvu zocheperako zakuthupi, zamaganizo kapena zamalingaliro kapena osadziwa komanso osadziwa ngati apatsidwa kuyang'anira kapena malangizo okhudza kugwiritsa ntchito chipangizocho moyenera ndikumvetsetsa. zoopsa zomwe zimachitika. Ana asamasewere ndi chipangizocho. Kuyeretsa ndi kusamalira ogwiritsa ntchito sikungapangidwe ndi ana popanda kuyang'aniridwa.
• Kugwiritsa ntchito m'nyumba kokha.
  Khalani kutali ndi mvula, chinyezi, kuwaza ndi zakumwa zamadzimadzi.

Malangizo Azambiri

• Onani za Velleman® Service ndi Quality Warranty patsamba lomaliza la bukuli.
• Dziwani bwino momwe chipangizocho chimagwirira ntchito musanachigwiritse ntchito.
• Zosintha zonse za chipangizocho ndizoletsedwa pazifukwa zachitetezo. Zowonongeka zomwe zimachitika chifukwa chakusintha kwa ogwiritsa ntchito pazida sizikuphimbidwa ndi chitsimikizo.
• Gwiritsani ntchito chipangizochi pazolinga zomwe mukufuna. Kugwiritsa ntchito chipangizocho m'njira yosaloledwa kumalepheretsa chitsimikizocho.
• Zowonongeka zomwe zimachitika chifukwa chonyalanyaza malangizo ena m'bukuli sizikuphatikizidwa ndi chitsimikizo ndipo wogulitsa sangavomereze vuto kapena zovuta zilizonse.
• Nor Velleman nv kapena ogulitsa ake akhoza kuimbidwa mlandu pakuwonongeka kulikonse (kwachilendo, kochitika kapena kosalunjika) - kwamtundu uliwonse (ndalama, thupi…) lobwera chifukwa chokhala, kugwiritsa ntchito kapena kulephera kwa mankhwalawa.
• Chifukwa chakusintha kosalekeza kwazinthu, mawonekedwe enieni azinthu amatha kusiyana ndi zithunzi zomwe zikuwonetsedwa.
• Zithunzi zamalonda ndi zowonetsera basi.
• Musayatse chipangizocho nthawi yomweyo chikayamba kukumana ndi kusintha kwa kutentha. Tetezani chipangizo kuti chisawonongeke pochisiya chozimitsa mpaka chifike kutentha kwa chipinda.
• Sungani bukuli kuti mugwiritse ntchito mtsogolo.

Kodi Arduino® ndi chiyani

Arduino® ndi nsanja yotsegulira magwero otseguka yozikidwa pazida ndi mapulogalamu osavuta kugwiritsa ntchito. Ma board a Arduino® amatha kuwerenga zolowetsa - sensa yowunikira, chala pa batani kapena uthenga wa Twitter - ndikusinthira kukhala zotulutsa.

• kuyambitsa injini, kuyatsa LED, kufalitsa china chake pa intaneti. Mutha kuuza gulu lanu zoyenera kuchita potumiza malangizo kwa microcontroller pa bolodi. Kuti muchite izi, mumagwiritsa ntchito chinenero cha pulogalamu ya Arduino (yochokera pa Wiring) ndi pulogalamu ya Arduino® IDE (yochokera pa Processing).

Zathaview

Zowonetsera za OLED ndizabwino m'njira zambiri. Amagwiritsa ntchito mphamvu zochepa, zowala, zosavuta kuwerenga ndi zazikulu viewing angle ndipo ali ndi kusamvana kwakukulu poganizira kukula kwawo kochepa.

Pitani patsamba lazogulitsa pa www.velleman.eu ndikutsitsa U8glib.zip file.
Yambitsani Arduino® IDE ndikulowetsa laibulale iyi: Sketch → Phatikizani Library → Onjezani laibulale ya Zip.
Mukamaliza, bwererani ku Sketch → Phatikizani Library → Sinthani laibulale, ndipo yendani pansi mpaka mutapeza laibulale ya U8glib. Sankhani laibulale iyi ndikudina "Sinthani". Tsopano muli ndi mtundu waposachedwa ndi examples.

Pitani ku Files → Eksamples ndikupitilira mpaka U8glib. Tsegulani exampndi Graphicstest.

Pazojambula "Graphicstest", mitundu ingapo ya zowonetsera zitha kusankhidwa. Ingosiyani "ndemanga" yomwe mukufuna.
Pa WPI438 muyenera kusiya ndemanga:
