Measure 3 analog values and present them on a graph


Recommended Posts

I would like to be able to print weight tickets from the Unistream, could we print to a printer via USB as long as it has linux drivers?

I also wonder what functions to use.

I already made an application that prints to Zebra printers (barcode printers). My application uses Ethernet protocol, but you  can do it using serial RS232. You can see the applications running here:

I want to use in my application controller HMI touch panel Unistream. I want to measure the three analog values​​, and visualize it on a graph. I want to connect the printer to panel. Can I print these trends? What functions to use to print my trends?


Best regards,


I don´t know if you can print directly your trends. If you need a fast solution, I will use the VNC option to see remotely on a PC with a printer and then use the Print Screen option. Then you can start looking a more sophisticated way to do it.
