open_dp100

DP100 power supplier from alientek

This project aim to make a free libarary that can communication with DP100 under any Operating System.

First is MacOs then linux, last is windows( or there won't be,because the official has provides one written in '.NET' ).

Protocol

see DP100_Protocol.md for protocol reverse engineering

Build

Steps

1. Download rust of you platform
2. cd this project dir
3. cargo build --release

A bin called 'cli' is under target/release/

This is the cli interface of this project

CLI usage

detail see cli -h

3 sub-commands is supported

1. ls : list connected DP100s
2. status : list DP100
3. set : change DP100 settings

Examples

• List current DP100s that connected

  cli ls

• List first DP100 device's status

  cli status

• List 2nd DP100 device's status

  cli status -d1

• Set first DP100 Output On

  cli set on

• Set DP100 complex 1

  cli set -d 1 config=5 v=12.00 ov=30.00 i=1.00 oc=2.00 on

  set second device switch to config 5,then edit the output value,at last turn it on

• Set DP100 complex 2

  cli set config=5 on

  Switch to config 5 and turn on

Library

WIP

Compatablity

Platform	Status	Note
Windows	Edit needs	There seemds a bug inside current version of hidapi crate under Windows,write function not sending all data,and first byte is missing.Edit is needed.
Linux	Not Tested	linux should work fine,but untested
MacOs	OK

Windows problem

When I use mingw gcc as a compiler,hidapi crate won't send all data as it should. I don't know whether it is a problem only occured on my PC or not. Some code has to be modified to adapt this. I hope new hidapi carate will fix it soon
