# MouseSelectDemo for SSD1306
|
||||||
|
Demo of selecting characters using the mouse.
|
||||||
|
I used [this](https://github.com/espressif/esp-idf/tree/master/examples/peripherals/usb/host/hid) 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 2/3 is not used in this project.
|
||||||
|
|
||||||
|
# USB wiring
|
||||||
|
To stabilize the power supply, I placed a 100uF electrolytic capacitor between 5V and GND.
|
||||||
|
```
|
||||||
|

|
||||||
|
|
||||||
|
|
||||||
|
# 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.
|
||||||
|
|
||||||
|
# Transfer failed error
|
||||||
|
For some reason, the following error may occur in rare cases.
|
||||||
|
This error occurs within [this](https://components.espressif.com/components/espressif/usb_host_hid) component.
|
||||||
|
It is unclear whether it is a component bug or an effect of electrical noise.
|
||||||
|
Some kind of stabilization circuitry may be required.
|
||||||
|
It may come back to life if you unplugging the mouse and plugging it again.
|
||||||
|
I would like to hear the opinion of someone who is familiar with USB electrical circuits.
|
||||||
|
```
|
||||||
|
E (12287696) hid-host: Transfer failed, status 1
|
||||||
|
E (12287696) usb_hid: HID Device, protocol 'MOUSE' TRANSFER_ERROR
|
||||||
|
E (15953516) USBH: Device 1 gone
|
||||||
|
```
|
||||||
|
|
||||||
|
# Keyboard with mouse function
|
||||||
|
I have a keyboard with mouse functionality, but the keyboard with mouse functionality does not work as a mouse.
|
||||||
|
