libneoradio2

C library (with Python bindings) for communicating with the Intrepid Control Systems neoRAD-IO2 product line — a family of ruggedized, isolated analog / digital / temperature DAQ devices that connect over USB. Up to eight devices can be daisy-chained, with 2.5 kV bank-to-bank isolation.

Install (Python)

pip install neoradio2

import neoradio2

for device in neoradio2.find():
    print(device)
    handle = neoradio2.open(device)
    # ... talk to the device ...
    neoradio2.close(handle)

Build from source

This repository uses git submodules for the HID backend and the frame description headers, so clone recursively (or initialize them after cloning):

git clone --recursive https://github.com/intrepidcs/libneoradio2.git
# or, in an existing checkout:
git submodule update --init --recursive

C library

cmake -S . -B build
cmake --build build

Add -DBUILD_SHARED_LIBS=ON for a shared library, or -DBUILD_PYTHON_BINDINGS=ON to build the Python extension via CMake directly.

Linux: install the udev rules so devices are accessible as a normal user — copy 99-intrepidcs.rules to /etc/udev/rules.d/, run sudo udevadm control --reload-rules && sudo udevadm trigger, and add your user to the users group (sudo usermod -aG users $USER). Build dependencies: sudo apt install cmake build-essential libudev-dev (Debian/Ubuntu) or sudo dnf install cmake gcc-c++ libudev-devel (Fedora).

Windows: Visual Studio 2019 or newer (MSVC) with CMake.
