HAMAPI Protocol Reference (BETA)

Overview

HAMAPI is a callsign watchlist and notification service for APRS. It lets users subscribe to callsigns they want to monitor and receive periodic APRS message notifications when those callsigns are active on the network.

What it does:

#!/usr/bin/env python3
"""Quick diagnostic: show station and packet age from packets.db."""
import sqlite3
import time
import sys
from datetime import datetime, timezone

DB_PATH = "/tmp/direwolf-dashboard/packets.db"
if len(sys.argv) > 1:
    DB_PATH = sys.argv[1]

# ILI9486.py — MHS35b/MHS35 variant (Pi 5 compatible, lgpio)
#
# Original: SirLefti/Python_ILI9486 (Waveshare)
# Modified: craigerl/hemna — MHS35b/MHS35 support + Pi 5
#
# Key differences from original:
#   - Uses lgpio (Pi 5 compatible) instead of RPi.GPIO
#   - regwidth=16: commands AND register data sent as [0x00, byte] pairs
#   - Pixel data (bulk framebuffer writes) sent as raw bytes
#   - Pixel format: RGB565 (0x55) instead of RGB666 (0x66)

# ILI9486_MHS35b.py — MHS35b variant support for Python_ILI9486
#
# Drop-in subclass of ILI9486 that provides:
#   1. MHS35b-specific init sequence (manufacturer registers, power/VCOM tuning)
#   2. RGB565 pixel format (16-bit) instead of RGB666 (18-bit)
#
# Usage:
#   from ILI9486_MHS35b import ILI9486_MHS35b, image_to_data_565
#   spi = SpiDev()
#   spi.open(0, 0)
