December to January 2024. Nim rewrite. Blog post. HN thread
  • Explore migrating from PIL to pixie-python make sense? We'd get great font rendering for free, minus emoji support sadly. --> Might be great, but putting energy into the next point instead.
  • Experiment if it makes any sense to rewrite the FrameOS on-device part in a compiled language. Conclusion: yes it does. We're doing real time graphics on low power devices. A compiled language brings 10x improvements in speed and/or performance. Migrating some parts to a compiled language is inevitable. After looking around a lot, nim seems like the best choice. People praise it. It's friendlier than rust/zig/go ("If you imagine native-compiled type-annotated Python where nearly 100% of your code is business logic with no cruft, you're getting close to the Nim experience."), it's easy to pick up from examples, fast, it's used for games (it's fast), and comes with an amazing image handling library and other goodies. None of the other languages hit this sweet spot, so let's go.
  • Rewrite FrameOS in nim.
    • Proof of concept in the nim branch
    • Deploy the nim code onto a raspberry with on-device compilation
    • Caching for on device compilation
    • Support for apps and the execution context
    • Support numbers, color and other types of fields
    • Support template strings in config -> inline code nodes for vars
    • Support edited custom apps
    • Convert to async server with schedules, etc
    • Scheduler
    • Inky impression display support? No C bindings? Only python available. Will call python code for now.
    • Rotated display support
    • System of hardware specific drivers, and devices that group them
    • Port over the main apps
      • Unsplash
      • Text
      • Code
      • Clock
      • Download URL
      • FrameOS Gallery
      • Color
      • Gradient
      • HA Sensor
      • If
      • Split
      • Resize
      • Rotate
      • OpenAI
      • Break if rendering
    • Log batching in a separate thread
    • Rendering in a separate thread
    • HDMI support (double buffering, frame info, different color modes)
    • Sanitize app fields
    • Display on/off controls
    • Skip most logs in high fps mode
    • Metrics logger
    • Waveshare eink support (using C libraries!)
    • Touch and click handlers
    • Ignore render when rendering, run all events after
  • 60fps mode (max 2fps with Python now) -> got 60fps+ (more like 100) on a rpi5 with a 720p display (pikvm). So it's possible, even with simple "software rendering". Once we have the basics covered, I can investigate something like boxy to increase performance even more.
  • Stability and hours of use (been running an inky impression + rpi zero w 1 and a hyperpixel round + zero w 2 at 24fps for days now without downtime)
  • Show errors when editing nim apps in the interface
  • Update docs Update for the nim rewrite frameos-docs#1

  • Merge the PR: Rewrite in nim #5
  • Add B/W and B/W/R waveshare drivers
  • Full screen mode in web server
  • Investigate timeouts hanging the logger
  • Delete old build folders on deploy
  • Any way to lock/secure dependencies
  • Global last image lock
  • Cache deps in docker
  • Show frame metric charts
  • Memory hole?? Memory is not freed when requesting the image over http.
  • Add dithering for 2-color waveshare devices
  • Add dithering for the rest
  • Add waveshare drivers
    • Black/White
    • 4-Grayscale
    • 7-color
    • 4-color Black/White/Red/Yellow
    • Black/White/Yellow
    • Black/White/Red
  • Compile lgpio from scratch if no package
  • Swap from string node ID-s in compiled scenes to integers (should speed it up a bit and reduce memory usage)
  • GPIO button handlers
  • Outgoing event nodes
  • Disable swap (saves SD card from death if we have a memory leak) --> revert? messes up compilation on W2
  • Faster compilation (was: local buildchains. Decided against it for now)
  • Inky impressions native driver. Went with faster python redeploys instead. The driver itself works fine as is, so not replacing today.
  • Logger crashes again, and takes its thread to 100%. Let's try again...
  • Debug toggle
  • Double check all the gcsafe hacks
  • General polish

Hey! I LOVE THIS PROJECT SO MUCH!

Good work man. I am very inspired by this.

Ideas:

  1. Simple http served frame for crappy devices (kobo aura HD etc) with really old browsers.
  2. "touch targets" for those crappy devices (so you can pretend to interact with Home Assistant toggles.

Thank you for this. I'm going to try to use it and try to contribute.
