Hi, I'm trying to capture sensor data from an USB-sensor. Datasheet of the sensor in attachment. The first problem is that Node-Red doesn't accept /dev/ttyUSB0 node that I would like to use in the project. After reading some other topics around here I found out that I can look after the correct name, using the lsusb command, and enter something like this /dev/bus/usb/002/002 into the Serial Input Port. Now I got conformation that the sensor is or not connected. But I didn't get any data out of it. I tried to do the same as in this project what is very similar to mine. But the debug output shows "Error: Error: Invalid argument, calling write" Can someone help me out? AttachmentHU USB Hall Probes 3036.pdf (134 Downloads) |
