Simple ToDO Viewer for Microsoft ToDos. Mirror of the private Gitlab repo that only synchronizes the main branch.
An ESP32 firmware project that pulls your Microsoft To-Do tasks via the Graph API and displays them on an e-paper screen. Written in C with PlatformIO, targeting low-power always-on display use. The author is clear this is unfinished and not ready for use.
The icon pipeline is well thought out — SVGs converted to pre-baked C header files at multiple sizes (12/16/24/48/256px) rather than doing runtime scaling on a microcontroller. Uses GxEPD2 which is the right library choice for e-paper on ESP32. Battery state tracking with orientation-aware icons suggests actual hardware testing happened.
The README is almost entirely 'tbd' — no wiring diagram, no build instructions, no OAuth setup guide, nothing. Last commit was August 2023 and it's still marked as not suitable for personal use, so this appears abandoned mid-development. OAuth2 token handling for Microsoft Graph on an embedded device is genuinely tricky (no browser, token refresh, secure storage) and there's no evidence that part is solved. Three stars and a mirror-only setup means there's no real community or maintenance path.
