PSU

A really simple command line interface for your bench power supply.

I've basically re-written this program countless times in countless languages in university and for jobs. I'm frankly rather surprised a tool like this doesn't already exist.

I made this one for my own power supply, but it's a little different from my previous implementations because it was designed to be very easy to contribute to.

Supported power supplies

I can only support what I can test and I can only test what I have, so this list is very limited at the moment. If your supply isn't here, consider contributing!

• BK Precision 1697 (should support 1696 and 1698 as well, but those are untested)

Installation

Currently I'm just distributing it through crates.io. You can run cargo install psu to get it. More packages may be added later.

Usage

Before you can use this tool you need to configure it, since it can't just magically discover your power supply (at the moment).

You'll need to put a config file under ~/.config/bench_psu_config.yaml. On Windows that'll just be a hidden folder in your home directory as well.

You will need to provide the following:

• default_interface - the name of the power supply that should be used by default.
• power_supplies - this is a list of power supplies you have configured your machine to use. It's a map of power supply names to their config.

Your config file may look like the following:

default_supply: bk_precision
power_supplies:
  bk_precision:
    !bk_precision_196x
      serial_interface: /dev/serial/by-id/usb-1453_4026-if00-port0

Each power supply's configuration is unique. You can find their individual documentation under power supply modules.

Contributing

I did my best to try and make this easy to contribute to, but feedback on how to streamline the process is welcome.

All files you add or modify need the license header. You can copy and update it from the main.rs file.

90% of contributions are likely to be drivers for new power supplies, since I can't add support for power supplies I don't have. Start by adding a power supply to the power_supplies folder. You'll create a submodule in that folder for your driver. See the BK Precision 196X driver as an example reference.
