VoiceNotes is an Arduino sketch for the Waveshare ESP32-C6-LCD-0.85 that records meetings and voice memos to microSD and turns them into notes: - Records 16 kHz mono WAV (up to 4 h) from the ES7210 dual mics, with a boosted preamp and soft-limited digital gain - Transcribes via an OpenAI-compatible speech-to-text API in ~10 min parts cut at quiet points, with retries and resume after failures - Summarizes the transcript with Claude into meeting notes (decisions, action items, topics with timestamps), streamed to and from the card - Copies the notes to Nextcloud over WebDAV - Shows recording/processing state on the 0.85" LCD and the LED ring - Works around the board's SD card failing multi-sector reads Credentials live in VoiceNotes/secrets.h, which is git-ignored; see secrets.example.h. Also adds the Microsoft CDM customer service SQL implementation (DDL, sample data, reporting queries and docs). Its README is renamed to CDM_README.md so the repository README stays at the top level.
