Podstawka do OLED i IMU

Podłączyć wyświetlacz OLED do płytki EduTar:

złącze wyświetlacza SDA – podłączyć do A4
złącze wyświetlacza SCL – podłączyć do A5
złącze wyświetlacza GND – podłączyć do GND
złącze wyświetlacza VDD – podłączyć do +5V

Uruchomić bibliotekę Adafruit_SH110x. Jeśli biblioteka nie jest zainstalowana w arduino to należy ją doinstalować przez menadżer bibliotek (Narzędzia->Zarządzaj bibliotekami… – wyszukujemy bibliotekę Adafruit_SH110x i klikamy przycisk „instaluj”)

Uruchomić przykładowy program:

#include <Wire.h>

#include <Adafruit_SH110X.h>

#define i2c_Address 0x3c //initialize with the I2C addr 0x3C Typically eBay OLED's

#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 64 // OLED display height, in pixels
#define OLED_RESET -1   //   QT-PY / XIAO
Adafruit_SH1106G display = Adafruit_SH1106G(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);
