Programmable DC Power Supply
I recently bought another Digital Power supply, going for a more professional model this time. The biggest advantage is this one does not have a fan.
So I decided to adjust my existing program HCS to also support this power supply. I tried to make a cleaner implementation then last time. It is not as good as I want it to be, but a start. So do you have a Elektro Automatik PS 2042-06 B or a Voltcraft PPS-11360 you can control them using this tool.
Usage
Set output voltage
$ HCS_DEVICE=/dev/ttyACM0 ./build/hcs eaps voltage 6
Read output volage
$ HCS_DEVICE=/dev/ttyACM0 ./build/hcs eaps voltage
> 5.94
Read output current
$ HCS_DEVICE=/dev/ttyACM0 ./build/hcs eaps current
> 1.03
Read device status
$ HCS_DEVICE=/dev/ttyACM0 ./build/hcs eaps status

TODO
- Update the documentation soon, currently it is lacking.
- Make a more consistent output.
- Fix command line parsing, so commands can be concatenated.
