Wsprry Pi Development

All current development has been done with g++ version 10.2.1 20210110 (Raspbian 10.2.1-6+rpi1). The compilation is done on Bullseye to allow the compiled executable to be run on Bullseye (old stable) and Bookworm (stable`).

Because of modularity, re-use, and licensing considerations, the central WsprryPi repository references the following Git Repositories as submodules:

• WsprryPi-UI: The Bootstrap-based Wsprry Pi Web UI.

• Broadcom-Mailbox: Boradcom’s interface for Mailbox communication.

• INI-Handler: A class that allows reading and wriging formatted INI cfiles.

• LCBLog: A class to handle log formatting, writing, and timestamps.

• MonitorFile: A class to watch a file for changes.

• PPM-Manager: A class to maintain an eye on the current PPM value for the OS/clock.

• Signal-Handler: A class to intercept various signals (e.g. SIGINT), and allow proper handling.

• Singleton: A class that enforces running only a single instance.

• WSPR-Message: A class that creates WSPR symbols from the callsign, gridsquare, and power in dBm.

• WSPR-Transmitter: A class that manages DMA work and scheduling for transmistting WSPR symbols.

In theory, this organization will allow more modular changes (like maybe adding Raspberry Pi 5 support?) in the future.
