Controlling a NI-DAQ board with c++
This repository demonstrates how to interact with a NI-DAQ board using c++.
In camera_pulse.cpp, I use a counter output to send a train of pulses at a specified frequency and duty cycle. In my experimental setup, I use this as a hardware trigger to a network of FLIR Blackfly S cameras.
In send_timestamp_as_bitcode.cpp, I use a hardware-timed digital output channel to send a bitcode (conveying a timestamp). In my experimental setup, I use this to synchronize data obtained on one computer (controlling a robotic arm) to an Intan board.
Ensure NIDAQmx has been installed.
For Ubuntu 20.04, compile using:
g++ send_timestamp_as_bitcode.cpp /usr/lib/x86_64-linux-gnu/libnidaqmx.so -pthread -o send_timestamp_as_bitcode
g++ camera_pulse.cpp /usr/lib/x86_64-linux-gnu/libnidaqmx.so -o camera_pulse
Run by executing:
./send_timestamp_as_bitcode
./camera_pulse
