microdeploy

Deploy project files on MCU as simple, fluid, and configurable.

This tool gives a per-project approach for uploading files to MCU. Per-environment support is intended - todo.

Features

• Configurable project files and environment - see example config: microdeploy.yaml
• Workflow support with a consistent CLI and API - see CLI Usage and Python Usage
• Pseudo-caching of MCU filesystem (hash cache)

Purpose

A KISS approach to wrap up existing CLI tools: ampy, terminal-s, (esptool, rshell), and fire.

— Note: Package adafruit-ampy-master is used instead of adafruit-ampy in order to allow upload progress display, because the official package is not up-to-date with master.

Installation

pip uninstall adafruit-ampy  # see requirements.txt (this is 0.0.1)
pip install --user microdeploy

microdeploy
microdeploy --help

CLI Usage

microdeploy                          # With default config file: microdeploy.yaml
microdeploy --port /dev/ttyUSB0      # Without config file
microdeploy --config other.yaml      # Use alternate config file
microdeploy --baud 115200 --port XYZ  # Override config

Python Usage

from microdeploy import Microdeploy

help(Microdeploy)

Without config file:

deploy = Microdeploy(port='/dev/ttyUSB0')

deploy.config.show()
deploy.device.ls()
deploy.device.put('main.py')
deploy.device.put('lib.py', '/lib/lib.py')

deploy.device.run('sandbox/test-something.py')
deploy.device.reset()

With config file (relative to cwd):

deploy = Microdeploy(config='microdeploy.yaml')

deploy.package.show('tests')
deploy.package.files('tests')
deploy.package.push('tests')

Example

Automation of deploy and run tests on MCU - see code in example/project.

Push the package (2 times to see the cache working):

python3 -m microdeploy -c example/project/microdeploy.yaml package push tests-run

Development

This prototype was written because I was tinkering with ESP in a project with multiple files. I was tired of forgetting to upload this or that file, and testing partly outdated code,
or needing to upload all files again every time. It became worse when I had to test my project on both ESP32 and 8266.

Project facts:

• Semantic Versioning is followed

• Stage of development: MVP

• The smaller the better: wc -l microdeploy/*
