EpomakerController 0.0.4

Epomakercontroller

Epomakercontroller

A CLI tool to interact with an Epomaker RT100 keyboard that comes with a small screen attached. Some features will probably also work with the TH80.

This project is still very rough around the edges!

NOTE!!!: This currently only works over the USB connection!

Features

• Upload images to the RT100 screen
• Send arbitrary numbers to the CPU and Temeprature displays on the screen
• Set RGB patterns on the keyboard
• Set individual key colours
• Start a daemon to continuously update the CPU and temperature on the screen

Requirements

I am using poetry v1.7.1

Installation

I suggest using conda or a python virtual env, tested on python 3.10 and 3.12:

Epomakercontroller package is available on PyPi

$ python3.10 -m venv epomaker
$ source epomaker/bin/activate
$ pip install EpomakerController

You can also install Epomakercontroller via poetry

$ sudo apt install poetry
$ git clone https://github.com/strodgers/epomaker-controller
$ cd epomaker-controller
$ python3.10 -m venv epomaker
$ source epomaker/bin/activate
$ poetry install

Usage

$ epomakercontroller
Usage: epomakercontroller [OPTIONS] COMMAND [ARGS]...

  A simple CLI for the EpomakerController.

Options:
  --help  Show this message and exit.

Commands:
  cycle-light-modes  Cycle through the light modes.
  dev                Various dev tools.
  list-temp-devices  List available temperature devices.
  send-cpu           Send CPU usage percentage to the Epomaker screen.
  send-temperature   Send temperature to the Epomaker screen.
  send-time          Send the current time to the Epomaker device.
  set-rgb-all-keys   Set RGB colour for all keys.
  start-daemon       Start a daemon to update the CPU usage and...
  upload-image       Upload an image to the Epomaker device.

Permissions

In order to communicate with your keyboard without having to use sudo, you can use the tool to generate a udev rule for the connected RT100:

epomakercontroller dev --udev

You will need to enter your password when prompted.

CPU/Temperature display

The temperature on the Epomaker screen is supposed to be for the weather, but I thought it was more useful to display the temperature of some device on the host machine. You will need to find out the label used by a sensor on your machine, which you can do by:

$ epomakercontroller list-temp-devices

Temperature key: nvme
  Label: Composite
  Current: 35.85°C
  High: 82.85°C
  Critical: 89.85°C
  Label: Composite
  Current: 44.85°C
  High: 82.85°C
  Critical: 89.85°C

Temperature key: amdgpu
  Label: edge
  Current: 40.0°C
  High: N/A°C
  Critical: N/A°C

Temperature key: k10temp
  Label: Tctl
  Current: 44.5°C
  High: N/A°C
  Critical: N/A°C
  Label: Tccd1
  Current: 39.0°C
  High: N/A°C
  Critical: N/A°C

Temperature key: mt7921_phy0
  Label: N/A
  Current: 28.0°C
  High: N/A°C
  Critical: N/A°C

Then you can start the daemon with the corresponding label, eg:

epomakercontroller start-daemon k10temp

Alternatively leave the label blank to disable and only do CPU usage:

epomakercontroller start-daemon

The daemon will also update the date and time once when it starts

Note about interface numbers

I only have my own keyboard to go by, but as far as I can tell there are 3 available HID interfaces available when the keyboard is plugged in over USB. All 3 of them will work with this controller HOWEVER using interface 0 interferes with regular usage of the keyboard (eg typing).

I have found interface 1 to be the best to use, but some commands take an option for you to set the interface number manually if you need to eg:

epomakercontroller start-daemon --interface 2

You can also print all the available information about the connected keyboard using the 'dev' command. Here is an example of the output from my own keyboard:

epomakercontroller dev --print
Printing all available information about the connected keyboard.
WARNING: If this program errors out or you cancel early, the keyboard
              may become unresponsive. It should work fine again if you unplug and plug
               it back in!
