that if you move a mouse cursor fast enough, you can get persistence of vision and, say...
*run a game of Pong inside your mouse's firmware*

Did this using a Seeed Studio XIAO RP2040 acting as a USB interceptor inside a cheapo HP mouse. Using @adafruit TinyUSB Arduino Library.

@gvy_dvpont I was going to ask if you were using absolute positioning, then I read your writeup to find you are!
Show threadGuy DupontAug 7, 2024
@Pheebe yep! I tried years ago with relative (since that was the default in the Arduino mouse lib) but the play box was so small since you can only jump by an 8 bit value each "frame"
Show threadPheebeUKAug 7, 2024
@gvy_dvpont and it's a signed value right?
Show threadGuy DupontAug 7, 2024
@Pheebe yup

lol someone on the other site requested that it do the DVD screensaver thing when it's idle ๐Ÿ˜€
Show threadBHSPitMonkeyAug 8, 2024
@gvy_dvpont Wait, it knows where the cursor's at in screen space? I would've figured it just sends relative movements, one way. I guess it's acting a little more like a trackpad?
Show threadGuy DupontAug 8, 2024
@BHSPitMonkey correct! I used a USB descriptor that defines the mouse as using absolute position.

@gvy_dvpont I wonder how this would look on a passive matrix LCD of yore.

@gvy_dvpont
Wow, this is awesome! So you are controlling the "right" cursor with your mouse and playing against an AI?

The obvious question now of course is: Can it run Doom?๐Ÿ™ƒ (Maybe if the cursor is moving really fast?๐Ÿค”)
