Feature Request: Text file viewer/editor for Meshtastic MUI (SD card integration) #215
Description
Summary
It would be great if the Meshtastic MUI could open plain-text (.txt) files stored on the SD card — for example, files placed in a /books directory for reading, and optionally allow creating or editing text files in a /memos directory for quick notes or logs.
Use Case / Motivation
Many users (especially those using Meshtastic nodes as standalone devices with displays) would benefit from basic local text access. Meshtastic MUI already provides key offline features — communication, maps, and node management.
Adding text viewing/editing would make the device even more versatile as an ultra-low-power, off-grid personal terminal.
Example scenarios:
- Reading documentation, offline guides, or short stories stored in
/books/ - Keeping logs, notes, or shared messages in
/memos/ - Writing down coordinates, checklists, or field data without needing a phone or computer
- Using a single Meshtastic device as an “all-in-one” companion — chat, maps, and notes — in remote or minimal setups
Possible Implementation Ideas
- File browser limited to
/booksand/memosdirectories on SD card - Simple text viewer (scrollable, optionally with font size selection)
- Optional minimal text editor for appending or editing memos
- UTF-8 plain text support
- Integration with existing MUI navigation (maybe accessible from the Tools or Utilities menu)
Why it fits Meshtastic’s philosophy
Meshtastic aims to enable resilient, low-power, off-grid communication.
Extending that philosophy to local text storage and reading aligns perfectly with self-sufficiency and decentralization — providing an offline knowledge and journaling tool within the same ecosystem.
TL;DR
Add support for viewing and editing plain text files from SD card (
/booksfor reading,/memosfor writing) directly within Meshtastic MUI.
