Simple OLED sample display sketch for ESP-PICO-tiny. Usage of I2C is different from ESP32-Dev board so please swap "pins_arduino.h" Before uploading binary, backup your original
pins_arduino.h
inside
Arduino/hardware/espressif/esp32/variant/esp32
and replace with the file in this repository, and install "Adafruit_GFX" and "ESP_SSD1306" libraries..
