# pi-pedalboard

Pedalboard implementation for Raspberry Pi microcomputer.

![pedalboard photo](./_stuff/pedalboard_photo_2_pluggable.jpg)

## Requirements

* Raspberry Pi microcomputer with GPIO (with Raspbian OS installed on it)

* Python3

* [`gpiozero`](https://pypi.python.org/pypi/gpiozero) and

  [`radio-class`](https://pypi.python.org/pypi/radio-class) python packages

* Some buttons connected to GPIO

  ([see here for mapping](https://github.com/unclechu/pi-pedalboard/blob/6bfb629fed36bb0f536d0ea523d6a08b7d8fb66e/server.py#L20-L26)

  and [see here for pins numbers](https://www.raspberrypi.org/documentation/usage/gpio/))

## Usage

For example you have connected to your Raspberry PI over SSH and it has

`192.168.1.10` IPv4 address (use `nmap 192.168.1.0/24` to find its address

if you don't know it already).

1. Go to directory that is cloned version of this repo,

   create and init

   [virtual environment](https://pypi.python.org/pypi/virtualenv):

   ```bash

   # python3 -m venv -- .venv

   # source .venv/bin/activate

   ```

   When I try to start `./server.py` with activated **virtualenv** everything is

   freezing on `s.bind((TCP_IP, TCP_PORT))` line, even SSH connection.

   After that any new attempt to establish SSH connection fails until I restart

   device by unplugging and plugging power cable again. So, **skip item 1 and

   item 2** and **install dependencies globally instead**:

   ```bash

   sudo apt-get install python3-gpiozero

   sudo pip install radio-class

   ```

2. Install dependencies:

   ```bash

   pip install -r requirements.txt

   ```

3. Run pedalboard server:

   ```bash

   ./server.py

   ```

4. Go to your host machine terminal

   (it supposed to be linux-based distro with X11,

   `xdotool` and python3 installed) and run

   (in directory that is cloned version of this repo):

   ```bash

   ./client_numpad.py 192.168.1.10

   ```

   It will start a daemon that simulates numpad keys pressing by pushing on

   buttons on pedalboard. You could use this as basic example for everything

   you could imagine. I'm actually using it for switching between

   [guitarix](http://guitarix.org/) presets.
