ezbeq 0.4.10

A small webapp which can send beqcatalogue filters to a DSP device

ezbeq

A simple web browser for beqcatalogue which integrates with minidsp-rs for local remote control of a minidsp or HTP-1.

Setup

Windows / MacOS

Python is required so use an appropriate package manager to install it.

chocolatey is a convenient choice for Windows homebrew is the equivalent for MacOS

Linux

Use your distro package manager to install python.

Installation

Example is provided for rpi users

$ ssh pi@myrpi
$ sudo apt install python3 python3-venv python3-pip libyaml-dev
$ mkdir python
$ cd python
$ python3 -m venv ezbeq
$ cd ezbeq
$ . bin/activate
$ pip install ezbeq

Using with a Minidsp

Install minidsp-rs as per the provided instructionshttps://github.com/mrene/minidsp-rs#installation

Using with a Monolith HTP-1

See the configuration section below

Upgrade

$ ssh pi@myrpi
$ cd python/ezbeq
$ . bin/activate
$ pip install --upgrade --force-reinstall ezbeq

then restart the app

Running the app manually

$ ssh pi@myrpi
$ cd python/ezbeq
$ . bin/activate
$ ./bin/ezbeq

Now open http://youripaddress:8080/index.html in your browser

Configuration

See $HOME/.ezbeq/ezbeq.yml

Options that are intended for override are:

• port: listens on port 8080 by default
• if using a minidsp
  • minidspExe: full path to the minidsp-rs app, defaults to minidsp so assumes the binary is already on your PATH
  • minidspOptions: additional command line switches to pass to the minidsp binary
• if using a htp1, add the ip address and named channels to which the filters should be sent. e.g. if the HTP1 is at 192.168.1.181 and only sub1 should be updated

htp1:
  ip: 192.168.1.181
  channels:
    - sub1

Starting ezbeq on bootup

This is optional but recommended, it ensures the app starts automatically whenever the rpi boots up and makes sure it restarts automatically if it ever crashes.

We will achieve this by creating and enabling a systemd service.

1. Create a file ezbeq.service in the appropriate location for your distro (e.g. /etc/systemd/system/ for debian)::

[Unit]
Description=ezbeq
After=network.target

[Service]
Type=simple
User=pi
WorkingDirectory=/home/pi
ExecStart=/home/pi/python/ezbeq/bin/ezbeq
Restart=always
RestartSec=1

[Install]
WantedBy=multi-user.target

2. enable the service and start it up::

$ sudo systemctl enable ezbeq.service
$ sudo service ezbeq start
$ sudo journalctl -u ezbeq.service

Aug 18 21:58:36 swoop systemd[1]: Started ezbeq.

3. reboot and repeat step 2 to verify the recorder has automatically started
