VP-Digi
Polska wersja tego pliku dostępna jest tutaj.
VP-Digi is a functional, affordable, easy-to-assemble, and configure STM32-based APRS digipeater controller with a built-in KISS modem.
- Multiple modems:
- 1200 Bd AFSK Bell 202 (VHF standard)
- 300 Bd AFSK Bell 103 (HF standard)
- 9600 Bd GFSK G3RUH (UHF standard)
- 1200 Bd AFSK V.23
- PWM (or deprecated R2R) signal generation
- Analog-digital busy channel detection (data carrier detection)
- AX.25 coder/decoder
- FX.25 (AX.25 with error correction) coder/decoder, fully compatible with Direwolf and UZ7HO Soundmodem
- Digipeater: 4 settable n-N aliases, 4 simple aliases, viscous delay (known from aprx) or direct only, black and white list
- 8 independent beacons
- KISS mode (can be used as an ordinary Packet Radio, Winlink, APRS, etc. modem)
- USB and 2 UARTs: independent, running in KISS, monitor, or configuration mode
Download and setup
The latest compiled firmware can be downloaded here.
Full documentation can be found here.
Updating to 2.0.0+ on older hardware
Since version 2.0.0, the component values have changed to provide support for faster modulations (9600 Bd). If you want to use these, some components must be replaced. For more information, refer to the manual.
Description, schematic, instructions
The user manual and technical description are available here.
Source code
The firmware was written using STM32CubeIDE, and you should be able to import this repository directly into the IDE. You can get the source code using:
git clone https://github.com/sq8vps/vp-digi.git
Since version 2.0.0, you will also need to get the appropriate submodule (LwFEC for Reed-Solomon FEC):
git submodule init
git submodule update
Since version 2.0.0, there is also a possibility to build the firmware with or without FX.25 protocol support. The ENABLE_FX25 symbol must be defined to enable FX.25 support. On STM32CubeIDE, this can be done under Project->Properties->C/C++ Build->Settings->Preprocessor->Defined symbols.
