WebDP100

A work-in-progress web-based driver (and maybe eventually GUI?) for the Alientek DP100 digital power supply, using WebHID.

Just plug in the DP100 using the USB-A to USB-A cable (make sure it's in "USBD" mode; double-tap ◀ to switch), and click connect!

Demo

Watch the video:

If you have a DP100, plug it in via USB, open Chrome and go to https://scottbez1.github.io/webdp100 to try this for yourself!

About

Implementation of the HID protocol is based on reverse-engineering the Windows library (ATK-DP100DLL(x64)_2.0.dll), which can be found on baidu or in the DP100-PyQt5-GUI project.

I don't plan on building a full-featured web interface, but if you want to, please feel free to use this as a starting point for your own project!

Usage notes

Linux

No drivers need to be installed, but the HID device may default to root-only permissions, resulting in "Failed to open the device" when you select it in the browser.

To adjust USB permissions, copy the udev/rules.d/99-atk-dp100.rules from this repo to the /etc/udev/rules.d/ folder on your computer, then run sudo udevadm control --reload-rules and re-plug the USB cable.

Acknowledgements

Shout out to @ElluIFX's DP100-PyQt5-GUI project as a helpful reference and source of the DLL for reverse-engineering.
