Replace crude 2-tap averaging with proper 15-tap half-band FIR filter for 16kHz→8kHz decimation (~60dB stopband attenuation, Kaiser beta=6). Exploits symmetry + half-band zeros for only 5 MACs per output sample. Separate TDM deinterleave (CH0 extraction at 16kHz) from FIR decimation for cleaner signal processing pipeline. Reduce ES7210 mic gain from 8 (24dB) to 5 (15dB) to avoid ADC clipping; AGC in the voice filter chain compensates for quieter input. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Pyxis
An LXMF client firmware for T-Deck, built on a highly modified fork of microReticulum
Very much WIP, don't expect stability :)
Features
Reticulum transport over:
- RNode-compatible LoRa
- AutoInterface (local wifi)
- TCP Client
- BLE Interface (barely working if at all)
Other features:
- GPS-synced time
- One really annoying beep when you get a new message (user toggle)
- View the announce stream
- Choose a propagation node (and sync with it)
- Set auto announce timer
- Light up keyboard (user toggle)
- Will crash in about 5 minutes of normal use (sorry)
Why "Pyxis"
Pyxis, latin for "compass," is a constellation in the southern sky depicting a mariner's compass. Small but essential, the compass ensures every message finds its destination - even when the path is uncertain.
