ut2xxx's Introduction

Simple DSO

This program is useful with UNI-T digital storage oscilloscopes UT2XXX or UT3XXX. It's intended to be a replace for original software, which doesn't work under Linux.

Requires pyQT5, QT 5, python 3, libusb and usb python module.

If your device is not found, you can add VID and PID to vid_pid.txt file and restart program. VID and PID is in decimal NOT hexadecimal !

Rules are added to udev rules.d and updated with relevant PID and VID. Any advice on how to proceed?
