Airspy and gnuradio-osmosdr

With Airspy it looks like that it and gnuradio-osmosdr:

https://github.com/airspy/airspyone_host#how-to-build-the-host-software-on-linux

sudo pacman -S base-devel cmake libusb pkgconf
sudo pacman -S boost swig cheetah

gr-osmosdr cmake

Location to put stuff

mkdir /home/pub
chdir /home/pub
chgrp users pub

Per User

useradd -m username
passwd username
chsh username
usermod -aG users,plugdev username

Wireless

pacman -S iw wpa_supplicant dhcpcd
# config /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
# do not enable any wpa_supplicant services otherwise dhcpcd hooks will not work

# looks like eth0 needs to be unplugged for routing or something to work.
# using dhcpd hooks to start wpa_supplicant
ln -s /usr/share/dhcpcd/hooks/10-wpa_supplicant /usr/lib/dhcpcd/dhcpcd-hooks/
systemctl start [email protected]
systemctl enable [email protected]

#systemctl start [email protected]

cpanp i <modules>

Note: Do not run cpanp as root it will error out

I2C

The power/telemetry/fan board utilizes I2C to gather data from sensors.

cpanp i Device::Chip::Adapter::LinuxKernel Device::Chip::INA219 # other modules may be needed

Modifications

changed Device::Chip::Adapter::LinuxKernel by un-commenting this line:

$self->{max_rate} = delete $args{max_bitrate}; # We're unable to affect this from userland it seems

changed Device::Chip::INA219 by modifying sub I2C_options to pass %params:

sub I2C_options
{
    my $self = shift;
    my %params = @_;

    my $addr = delete $params{addr} // 0x40;
    $addr = oct $addr if $addr =~ m/^0/;

    return (
        %params,    # pass the parameters along
        addr        => $addr,
        max_bitrate => 100E3,
    );
}
