The initial release allows the user to interact with the running program to set the configuration values. The project is created using the Raspberry Pi Pico SDK in C++. Visual Studio Code is used as the IDE. Follow the instructions regarding setup and configuration of VSCode from the RPi Pico "Getting Started" document if you wish to build and/or modify the code to your liking. Included here is the PicoAPRSTracker.uf2 file which may be loaded onto the Pico and used as documented.
The configuration parameters are:
Source Call Sign
Digi 1
Digi 2
Comment
Interval (min)
APRS symbol character
Configuration is done via the USB port when the Pico device is connected to a serial terminal on a computer. Please see the CONFIGURATION.md file for more VERY important information.
See the ELECTRONICS.md file for more information regarding building an appropriate circuit to use with the Pico. This would include a UART to RS-232 converter module to connect to the KISS modem in use, and a GPS receiver module which provides position and time information to the program.
