    Ak chcete zapojit 2 a viac I2C zariadeni na mikrokontroler "LilyGO TTGO ESP8266 0.91" OLED WiFi Modul", tak treba vzdy pred ich pouzitim (citanim) inicializovat, v arduino IDE napr. takto: "Wire.begin" v "loop" funkcii. V opacnom pripade I2C nefunguje podla ocakavani. MJ

    Kdyz nekdo bude to zkusit zapojit na neco jineho s I2C, skutecne zapojeni I2C OLED na desce: OLED_SDA - GPIO02/SDA, tam kde je nakreselno GPIO04/OLED_RST OLED_SCL - GPIO15/SCL OLED_RST - GPIO04, tam kde je nakreslen GPIO0/CS2 jinak - funguje dobre s Arduino_ESP8266 library
