Installere Arduino IDE Software

Før du kan starte din programmering skal Arduino’s IDE software hentes. Dette program bruges til at programmere din arduino.
Download fra dette link: Download

Installere ESP package (Arduino IDE)

Åben Arduino IDE (Download her)
Klik “Fil/Egenskaber”
Indtast dette link i feltet “Additionel Board Manager URL’s”
Link “https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json“
Klik OK
Åben “Værktøj/Board/Boards manager” (Lad programmet opdatere)
Find “ESP32” og installere
Klik derefter “Værktøj/Board” og find (ESP32C3 Dev Module)
Du er nu klar til at sende en kode

Installere u8g2Library

• Download library (Download)
• Åben Arduino IDE software og klik på “Sketch/Include library”
• Klik nu på “Add Zip. library” og find Zip filen du lige har downloaded.
• Luk, og åben Arduino IDE programmet. (Genstart programmet)
• Nu er library installeret.
• Library kan også downloades direkte i Arduino IDE find den her: “Sketch/Include library/Manage library/U8g2 – by Oliver”

Eksempel

Her præsenteres en hurtig visuel demonstration af den kompakte OLED-skærm, som giver et klart indtryk af dens funktionalitet og detaljer.

U8g2lib Example Overview:
Frame Buffer Examples: clearBuffer/sendBuffer. Fast, but may not work with all Arduino boards because of RAM consumption
Page Buffer Examples: firstPage/nextPage. Less RAM usage, should work with all Arduino boards.
U8x8 Text Only Example: No RAM usage, direct communication with display controller. No graphics, 8x8 Text only.
