Redpitaya Compatible Firmware

We ported several SDR applications from Redpitaya Notes with all source code available in the repo. Thank Pavel Demin to bring a such great project to the community.

Warning

The Redpitaya Firmware is designed to allow users to experiment with various exciting SDR applications from Redpitaya-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 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 16bit ADC
  • Leverage built-in GPS module
  • No DAC and other GPIO

The basic instruction is still valid as Pavel's redpitaya Notes project stated here. One exception is that web-888 hardware can be reached via 'web-888.local' name.

The bootloader of firmware setup Web-888 specific GPIO and configure Si5351 to output 122.88Mhz clock to ADC. The applications are largely untouched except removing transimition functionality.

Listed several key applications for reference. We encourage hackers to use this as a start point to create more interesting applications. We 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 the sampling rate of 48, 96, 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. Also it can be used as Skimmer server as well.

  3. Multiband WSPR transceiver

    A 8 channels WSPR digi skimmer which is able run without additional PC or RaspberryPi.

  4. Multiband FT8 transceiver

    A 8 channels FT8/FT4 digi skimmer which is able run without additional PC or Raspberry-Pi.

  5. Wideband SDR transceiver for GNU Radio

    up to 2500kbps wideband receiver application which supports experiment in GNU Radio.
