Sdrberry wayland

Raspberry pi SDR transceiver / frontend using lvgl gui supporting Raspberry pi OS Wayland. !!! This is an ongoing project code only for information purpose only. The main goal for this project is to learn about c++ programming, liquid dsp, and for most the use of the GUI toolkit LVGL v9 Functionality is in beta currently

This source code is still in development.
Goal is to support Adalm pluto SDR, Radioberry, RTL-SDR, SDRPlay, TRX-DUO etc but it should also support other SDR receivers based on SoapySDR. Also the goal is to support optical encoder and support I2C / serial interface for bandpass filtering I use an ESP32 as CAT controller with a service for an optical encoder. Alternative a Contour Shuttle express can be used as rotary controller and or a mouse.

install script install.sh installs all components based on a fresh raspberry pi USB drive or SD card (OS should be updated)

• SoapyRadioBerry (support radioberry)
• libiio (support for Adalm Pluto SDR)
• libad9361-iio (support for Adalm Pluto SDR)
• pthread
• liquid-dsp
• fftw
• civetweb
• nlohmann json
• HowardHinnant date.h library
• wsjtx_lib

Installation

Preparation before install

Take a good quality USB drive and install the latest 64 bit Raspberry OS on it. I advise not to use SD cards, these are very slow and often fail in a short time. Use raspi-config to switch to GUI auto logon startup. Update the OS with the latest raspberry pi OS patches

Pi 5 considerations

This wayland version works both on Pi4 and Pi5 Trixie Raspberry pi OS Older distributions are not tested and not supported.

Pi 5 and Radioberry considerations

To use the pi5 and the radioberry there are two options for the radioberry driver.

1. Use the GPIO version of the driver. This version will work directly on Raspberry pi OS but has some performace limitations. Use this version only with lower samplerates like 96 Khz or lower.
2. Use the PIO driver. This driver uses DMA to transfer the data from the Radioberry to the pi and is very efficient. It has no samplerate limitation, only requires a patched Linux kernel. Supplied by PA3GSB or you can patch the kernel your self.

Install and compile with cmake

Download the install file in pi home directory (the install script supports different SDR's) SDR Unit being used Supported: hackfr = HRF / HifiBerry = HFB / Pluto = PLT / RadioBerry = RDB / SDRPlay = SDP /RTLSDR RTL / No = No device

wget https://raw.githubusercontent.com/paulh002/sdrberry/master/install/install.sh
chmod +x install.sh
./install.sh RDB

create menu short cut

copy sdrberry.desktop to ~/.local/share/applications

cp ~/sdrberry/install/sdrberry.desktop ~/.local/share/applications/sdrberry.desktop
sudo chmod +x ~/.local/share/applications/sdrberry.desktop
update-desktop-database ~/.local/share/applications

Raspberry pi Touch 2 7 or 5 inch desktop rotation

To rotate the Raspberry Touch 2 displays permenent execute folowing script.

chmod +x ./sdrberry/install/desktop-rotation.sh
./sdrberry/install/desktop-rotation.sh

autostart

To automaticly start sdrberry edit:

vi ./config/labwc/autostart
sdrberry >> /home/pi/sdrberry.log 2>&1

Or combine with screen rotation

vi ./config/labwc/autostart
wlr-randr --output DSI-1 --transform 90 &
sdrberry >> /home/pi/sdrberry.log 2>&1

Slow Mouse configuration

Wayland supports a mouse, to improve responsiveness the install script will add usbhid.mousepoll=2 to the commandline.txt

start sdrberry

From the Accessories menu choose sdrberry to start the software. Or start from cli in that case make sure the WAYLAND_DISPLAY environment variable is set.

export WAYLAND_DISPLAY=wayland-0
sdrberry > sdrberry.log 2>&1

WSPR support

Sdrberry can receive and decode wspr messages

Integration with JS8CALL

Sdrberry can communicate with js8call using pipewire on the same pi To configure pipewire execute the setup-pipewire.sh Sdrberry emulated the CAT interface of an yeasu ft891 using tcp/ip. For js8call to connect to the radioberry we need to patch hamlib. This is automaticly done using the install_js8.sh script.

./setup_pipewire.sh
./install_js8.sh

Tranceiver with sdrberry and radioberry

I2C configuration

WSJT-X & CAT integration for logging software

Sdrberry sends messages to Qlog (or other logging software like NN1MM) And can be remote controled by logging software using CAT FT-981 commands.

Web Server on port 8081

First version of sdrberry webserver, goal is to remote control the functions of sdrberry. This is still an experiment / beta version. To see what is the best way to integrate web with C++ application. WEB pages are build with VUE JS 3 and Primevue source code will be shared later in separate github repo.
