Red Pitaya Compatible Firmware

We ported several SDR applications from Red Pitaya Notes, with all source code available in the repo. Thank you to Pavel Demin for bringing such a great project to the community.

Warning

The Red Pitaya Firmware is designed to allow users to experiment with various exciting SDR applications from the Red Pitaya Notes project on Web-888 hardware. The RX-888 team provides limited support for firmware issues specific to the Web-888 hardware. However, further enhancements and developments of the firmware are primarily driven by the community.

We modified the red-pitaya-notes projects to make the following changes:

  • 122.88MHz as the clock
  • 7010 as the main CPU which limits the channels
  • Single ADC channel but 16-bit ADC
  • Leveraged built-in GPS module
  • No DAC and other GPIO

The basic instructions are still valid as stated in Pavel's Red Pitaya Notes project here. One exception is that the Web-888 hardware can be reached via the 'web-888.local' name.

The bootloader of the firmware sets up Web-888 specific GPIO and configures the Si5351 to output a 122.88MHz clock to the ADC. The applications are largely untouched except for removing transmission functionality.

We've listed several key applications for reference. We encourage developers to use this as a starting point to create more interesting applications. We've published some hardware information which is useful during development.

Ported SDR Applications

  1. SDR Receiver

    This is an application to support CW Skimmer and Reverse Beacon Network Aggregator. It offers 8 channels with sampling rates of 48, 96, and 192 kSPS.

  2. SDR Receiver Compatible with HPSDR

    You can use any SDR GUI client that supports HPSDR to connect. There are several applications available to use. It can also be used as a Skimmer server.

  3. Multiband WSPR Transceiver

    An 8-channel WSPR digi skimmer which is able to run without an additional PC or Raspberry Pi.

  4. Multiband FT8 Transceiver

    An 8-channel FT8/FT4 digi skimmer which is able to run without an additional PC or Raspberry Pi.

  5. Wideband SDR Transceiver for GNU Radio

    Up to 2500kbps wideband receiver application which supports experimentation in GNU Radio.
