MouseMoveDemo for SSD1306

Demo of moving a circle using the mouse.
The circle moves when you move the mouse.
I used this as a reference.

Hardware requirements

• ESP32S2/S3
  These have USB-HOST functionality.

• USB Connector
  I used this:
  

• USB mouse
  2-button or 3-button usb mouse.
  Button 3 is not used in this project.

How to Use

The circle moves when you move the mouse.

Invert with left mouse click.

Right click the mouse to go back.

USB hot socket

There are times when it works correctly and times when it doesn't.
It works more stably if you connect before starting the firmware.
When it works correctly, a log like this will be displayed.

I (1166) usb_hid: hid_host_device_callback
I (1166) usb_hid: HID Device, protocol 'MOUSE' CONNECTED

Using USB-HUB

I tried it, but it doesn't work properly via USB-HUB.
