After downloading the zip file from the above drive link, you need to extract the file.

There are two files in the extracted folder. Keep the two files ( ino file and bitmaps.h file) in the same folder.

If you face these errors:
A. Code error when uploading?
Solution: use latest arduino ide, install esp32 boards correctly, install u8g2 library.

B. Code uploaded but nothing on screen?

Solution: "Enable" USB CDC on boot, from Arduino IDE > Tools. Also check wiring diagram.

C. Icons move fast/ abnormal display?
Solution: Is that correct display ?( SSD1306) All four button pins must be connected. (If you use normal OLED without buttons, button pins must be pulled HIGH / connect to resistor and 3.3v)
