Luna makes several API’s available for the Hyperion in several programming languages including C#, Labview, Matlab, Python and C++. The API’s are available for download at https://lunainc.com/product/hyperion-si155 under the software tab (the API’s are the same for both the SI155 and SI255). Each download also includes an example folder to get you started.
The ODiSI does not have an API, but it does support streaming over a TCP/IP connection in a JSON format. To enable this feature, go to settings -> streaming and enable streaming. In addition, this tab will show you the IP address and streaming port number.
