EPyQ is a cross-platform PC service tool for EPC Power power conversion modules. It is distributed for Windows and developed in Linux but has been run once on OSX (to the point of loading the GUI).
Primary communication is done over CANbus using pythoncan and Twisted.
The GUI is written in PyQt5.
Most of the interesting parts of the GUI are loaded from device configuration files including .ui Qt GUI files and PEAK PCAN .sym files for CANbus message definitions.
Instructions are for Python 3.8, but they should work with higher versions.
-
Install Python 3.8
-
Install Git
-
git clone https://github.com/epcpower/st -
cd st -
git submodule update --init -
poetry install -
poetry run buildui -
Note the links provided for possibly needed system and driver extras.
-
Try running
poetry run epyq. If you get errors, consider installing the linked extras.
If using with PEAK PCAN hardware, install the PEAK drivers.
Select the PCAN-Basic feature in the installer. The virtual and LIN features are not needed for this.
To launch EPyQ run poetry run epyq.
To launch Qt Designer with the EPyQ plugins enabled run designer.bat.
EPyQ widgets should be visible at the bottom of the widget box on the left.

If it works, continue below regarding CAN bus setup
In Linux, EPyQ does not attempt to configure or bring up the socketcan links despite still showing the baud rates. Presently the user must set these up themselves prior to opening EPyQ since it detects on startup. As reference, the script below is used during development on Ubuntu 16.04 (Xenial) with a PEAK PCAN USB adapter for a 500kbps bus.
#!/bin/bash
sudo modprobe -a can can_raw
for e in 0 1; do
sudo sh -c "echo $e > $(dirname $(sudo grep --files-with-matches --recursive --include=idVendor 0c72 /sys/bus/usb/devices/* | head -n 1))/authorized"
