Slime OS is an app launcher for the PicoVision (and soon other RP2040 and RP2350 devices). It was originally designed for the Slimedeck Zero, a mini cyberdeck project. However I hope to expand it to other devices and form factors.

Slime OS runs in a limited 32-color mode with a 400×240 internal resolution which is interlaced up to 800×480. This resolution should scale well on most HDMI displays.
- Flash the widescreen build of the PicoVision firmware to your PicoVision CPU.
- Use Thonny to replace the contents of your PicoVision Micropython filesystem with the files in
src.
Please refer to an example app for boiler plate.
Slime OS includes various libraries which are used internally but may also be helpful when making apps.
Begin by importing slime_os…
| Slime OS Library | Description |
|---|---|
| sos.gfx | Drawing methods including shapes, text, and other utilities. |
| sos.intents | Intents are used to send signals from an app to the OS, including quitting the app, swapping apps, or flipping the frame buffer. |
| sos.ctrl | Controller for identifying expansions. |
| sos.kbd | Keyboard instance for reading buttons. |
This software is experimental and does not work completely, specifically issues include…
- Input is only supported via an i2c keyboard, which is not documented (hoping to add USB keyboard soon)
- Some apps are upside down due to the Slimedeck having the screen rotated 180 degrees. Newer apps use the
sos.graphics.*methods which support

Multiple buffering; https://en.wikipedia.org/wiki/Multiple_buffering
Wikipedia has "page flipping" but not "physical double-buffer"? TIL about triple buffering, and quad buffering for stereoscopic applications.
