| 1 | Instec said: “While we do have sample code for Python, it is based on a USB connection, not Ethernet. Our documentation on Ethernet programming is limited because it isn’t very frequently used for custom applications. This ZIP file contains example code for python using a USB connection. It could serve as the basis for an ethernet version.” | email from Instec | |
