This project aim to use the python scripts to communication with Alientek DP100 power supply.
The config.txt is used to configure the output voltage and the trip current.
Use powerup.py to load the configuration from config.txt, and enable the output.
Use powerread.py to read the status (VIT) from DP100.
Use poweroff.py to disable the output.
This project is based on the hid and crcmod libraries.
Before run the script, you have to follow the instruction from this page to install the necessary libraries. In Ubuntu, sudo apt install libhidapi-hidraw0 works for this project.
Then sudo pip3 install crcmod hid
- HIDException('unable to open device')
Check if plug in the DP100 using the USB-A to USB-A cable, and make sure it's in "USBD" mode. Usually "USBD" mode is the default mode, you can double-tap ◀ to switch between USBD and USBH.
Use lsusb to check the usb bus number for "ALIENTEK ATK-MDP100", and use ls -al /dev/bus/usb/xxx/ (xxx is the bus number for DP100) to check if the user has the permission to access the usb port. Note the HID device has root-only permission by default. To adjust USB permissions, copy the 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.

We have problem with Python hid on windows OS, the first byte is always missing during write operation.
-
Mac OS is not tested yet.
-
open_dp100 helps to understand the protocol between host and DP100, this project is migrated from open_dp100.
-
webdp100 is a program to interface DP100 through the chrome or edge browser.
-
DP100-PyQt5-GUI use ALIENTEK's DLL to control and monitor the DP100. But this DLL is based on microsoft dotnet, I failed to migrate it to linux.
