A basic REPL for crow with some utilities

Requirements:

• Python 3.5+
  • Windows & OS X: https://www.python.org/downloads/
  • Linux: sudo apt-get install python3 python3-pip or equivalent
• pip and setuptools
• pyserial and prompt_toolkit

Note: you might need to use python and pip instead of python3 and pip3 depending on your platform. If python3 is not found, check that you have python >= 3.5 with python --version.

Install and run:

# Ensure setuptools is up to date
pip3 install --upgrade setuptools
# Install druid
pip3 install monome-druid
# Run druid :)
druid

Start by running druid

• type q (enter) to quit.

• type h (enter) for a list of special commands.

• input values are printed on the top line

• will reconnect to crow after a disconnect / restart

• scrollable console history

Example:

druid
//// druid. q to quit. h for help

> x=6

> print(x)
6

> output[1].volts = 0

> q

Execute a lua script and enter the REPL from the command line:

druid examples/test-2.lua

Diagnostic logs are written to druid.log.

python3 upload.py examples/test-2.lua

Uploads the provided lua file to crow & stores it in flash to be executed on boot.

python3 download.py

Prints to screen. Copy to file by running:

python3 download.py > feathers.lua

Druid comes with a bunch of example scripts to help introduce crow's syntax, and spur your imagination with some zany ideas. Here's the list with a brief description of each (most scripts have a longer description including the assignment of ins and outs at the top of the script):

• boids.lua: four simulated birds that fly around your input
• booleanlogic.lua: logic gates determined by two input gates
• clockdiv.lua: four configurable clock divisions of the input clock
• cvdelay.lua: a control voltage delay with four taps & looping option
• gingerbread.lua: clocked chaos generators
• samplehold.lua: sample and hold with quantization & randomness
• seqswitch.lua: route an input to 1 of 4 outputs with optional 'hold'
• shiftregister.lua: output the last 4 captured voltages & play just friends
• stop.lua: reset crow
