The Library Manager is a newer feature of the Arduino IDE. Many of the popular libraries, including most of Adafruit's, are in the Library Manager. If you are looking to work with other people's libraries, first check the Library Manager to see if the library is there first rather than downloading a copy into your local libraries. Installation Follow the appropriate steps below depending on your platform to install the Bluefruit LE Python library. Mac OSX On Mac OSX nothing extra needs to be installed to use the library. May 27, 2016  DEPRECATED! Please use Adafruit Blinka instead (was: Library to provide a cross-platform GPIO interface on the Raspberry Pi and Beaglebone Black using the RPi.GPIO and AdafruitBBIO libraries.) - adafruit/AdafruitPythonGPIO.

  1. May 27, 2016  Adafruit Python BluefruitLE Python library to simplify access to Bluefruit LE (Bluetooth low energy) devices and services on Linux and Mac OSX. Hides all the platform-specific BLE code (using BlueZ on Linux and CoreBluetooth on Mac OSX) and provides a simpler syncronous BLE API which is great for scripts and other automated tasks using BLE.
  2. May 16, 2012  Slowly building up a collection of parts we use here. This file includes some library parts from microbuilder.eu Most of 'em are either Eagle parts that I've changed a little to make them easier to solder, some are 'handmade' and a few are from microbuilder.eu Its released into the Public Domain - that means you can do whatever you want. We'd like it if you kept the author email/url in the.
  3. Adafruit's CircuitPython is great for making slide show galleries that playback audio and display images. Use the capacitive touch pads on the HalloWing for input commands. You can rapidly update your code without having to compile and there's plenty of libraries, examples and support.

The HalloWing PCB press fits into the face plate without screws and snap fits into the case. Speaker is housed in a back door with a working hinge. Parts 3D print without any supports!

No soldering necessary! HalloWing is pre-assembled and speaker is wired so it's plug-n-play! 3D print the case and snap fit everything together for easy assembly.

Author Notes:

My first computer was an Apple Mac Performa 6300. I remember attempting to fix a Macintosh 128k in middle school because I told my teacher I owned an Apple computer. I was not able to get it running.

Phil Torrone (Mr. Ladyada) comes up with the best project ideas!

Circuit Diagram

This provides a visual reference for wiring of the components. They aren't true to scale, just meant to be used as reference. This diagrams was created using Fritzing software.

Adafruit Library for Fritzing

Use our Fritzing parts library to create circuit diagrams for your projects. Download the library or just grab the individual parts. Files are hosted on our github repo linked below.

Powering

The Adafruit HalloWing M0 Express can be powered via USB or JST-PH using a 3.7v lipo battery. In this project, USB power is used. Optionally, a 500mAh battery can be used to make it portable – Also fits nicely inside the case. The lipo battery is rechargeable via the USB port on the Adafruit HalloWing M0 Express.

Circuit Python Code

The code for this project was developed using Adafruit's CircuitPython and documented in John Park's tiny museum project. Head on over there and follow the tutorial to setup CircuitPython on your HalloWing M0 Express.

Mu: Python IDE

Check out the Mu Python editor for writing CircuitPython code you can easily save and load to your Adafruit supported hardware. Use the built-in serial console for debugging and the plotter for visualizing data. Download the software and check out the learn guide for installation help.

Mac Media Assets

Once you have CircuitPython installed and setup on the HalloWing M0 Express, you can download the assets for this project. This includes bitmap images of the Mac OS boot screens and chime audio wav files. These are included in the download link in the 3D printing page.

Adafruit Library For Mac Pro

Upload Media Assets

Download the .zip file, and then uncompress it. Drag the .bmp and .wav files onto your HalloWing – CIRCUITPY. They must be at the top level of your HalloWing, not inside a folder.

Make sure the code.py and adafruit_slideshow.mpy files have been copied over.

Creating Custom Assets

The tiny museum project also covers how to create custom images and audio assets. If you're interested in creating your own assets for this project, be sure to walk through this page.

The Mac OS chime sounds were recorded from this YouTube Video. It also has 'crash' sounds.

The Mac OS boot screens were found in this blog post that features several others.

Reboot and Play Chimes

The capacitive touch pads are used to advance to the next image or the previous image. The code looks for .bmp files to play -- when it finds one it then parses that filename and looks for a .wav file with the same name. For example, macos8.bmp would cause the code to look for a macos8.wav file to play.

3D Printed Parts

Parts are designed to be 3D printed with FDM based machines. STL files are oriented to print 'as is'. Parts are listed below with file name and description. Parts require tight tolerances that might need adjusting slice setting. Reference the suggested settings below.

Print-In-Place Hinge

The STL file named hallowmac-case-back features a back door panel with a print-in-place hinge – This allows the panel to swing open and shut closed. The door panel is designed to house the min oval speaker. Tolerances in the hinge are designed to print using FDM 3d printers.

Parametric 3D Object

3D print the hinge-tester.stl file before printing the hallowmac-case-back.stl. See how the tolerances are and adjust slice settings if necessary. The door hinge in this project inspired me to create a parametric model that can be used in future projects. Here's a short video demonstrating how to scale up the hinge mechanism using Fusion 360's user parameters.

Simple Enclosure

The STL file named hallowmac-case does not feature the print-in-place door hinge. 3D print the file named hallowmac-back.stl for the back panel – This houses the mini overal speaker and snap fits into the back of the case. Optionally, a bottom panel cover (hallowmac-bottom.stl) snap fits into the bottom of the case – This could be useful for housing extra components or a lipo battery pack.

Download the 3d model of the Adafruit HalloWing M0 Express and use it to create new cases, enclosures and props! The design features headers, connectors and the display for making accurate snap fit parts.

HalloWing Faceplate

Adafruit Library For Arduino

The HalloWing PCB is secured to the 3d printed face plate without any machine screws. Four built-in standoffs elevate the PCB and two clips holds it down.

Installation

Start by orienting the HalloWing PCB with the face plate. Position the PCB over the faceplate with the screen facing down. Insert the PCB into the clips by sliding it into place – PCB may need to be slightly angled. Press down on the PCB so the pegs in the standoffs go through the two mounting holes.

Connect Speaker

Grab the pico blade connector from the speaker and plug it into the port on the back of the HalloWing. The side with the two distinct tabs faces up with the PCB.

Install Face Plate to Enclosure

Place the speaker over the HalloWing PCB. Line up the faceplate with the case and lay it on top of the opening. Press the faceplate into the case so the lips are inserted. The two edges snap fit and 'click' into place.

Install Speaker

Open the back door of the case by pushing it outwards. The inside has a cavity designed to house the mini oval speaker. Place the speaker into the cavity and press down. Optionally, remove the protective backing by peeling it off – Sticky adhesive is lined on the outline.

How to go to library mac. Jul 22, 2011  Use “Go To Folder” and Open /Library/ Directly. All you need to do is hit Command+Shift+G from the Mac desktop (or Finder Go Go to Folder) and type in /Library to temporarily access the Library directory in the Finder. When you are done, close this window and it will no longer be visible. May 30, 2019  Despite the fact that Apple keeps the Mac Library folder hidden from users, it’s good to learn how to show the Library folder on Mac. You may need to access the Library folder when you need to clear cache, remove the app’s leftovers, edit preference files manually, etc. Access Library Folder On Mac. The Library Folder on your Mac contains Preference Files, Caches, and Application Support Data. While regular Mac users may not find the need to access the Hidden Library Folder, advanced Mac users will at times come across the need to access files inside the Library Folder for troubleshooting and other purposes. Jan 12, 2020  It's not clear why Apple decided to hide the user's Library folder, but you have multiple ways to get it back: two Apple provides (depending on the version of OS X you are using) and one in the underlying file system. The method you use depends on whether you want permanent access to the Library folder or only when you need to go there.

Close Door

With the speaker secured to the door, close it back up by pressing down on the edge – The nub will engage the latch inside of the case. To reopen press the door open from the inside. Use both hands and fingers to carefully open and close the door, the latch might get damaged if the door is pressed all the way through.

Play Chimes

Touching the capacitive pads on the HalloWing PCB will play the chime and cycle through the different boot screens. Tap and hold to continuously play through all of the assets.

RASPBERRY PI/PI A+, B+, 2, 3PROGRAMMING/PYTHONINTERNET OF THINGS - IOT/BLUEFRUIT / BLE

So you've got a Bluefruit LE device that's ready to be the next awesome wireless IoT gadget, but how do you actually talk to it from your computer? The Bluefruit LE Python library is just what you need to write code that reads and writes data with a Bluefruit LE device! This Python library allows you to write simple code to talk to a Bluefruit LE UART from a Mac OSX computer or Linux machine, like a Raspberry Pi. This library is great for logging sensor data, controlling your device, and much more through the wireless magic of Bluetooth low energy!

Adafruit Gfx Library Tutorial

To use this library you'll need to be running a Mac OSX or Linux machine with a Bluetooth 4.0 low energy adapter. Sorry Windows is not yet supported because Bluetooth low energy support is still a little bit too new to the platform (only the very latest Windows 10 release exposes enough BLE APIs to completely control a device). In the future Windows support might be added, but for now stick with a Linux machine, like a Raspberry Pi, or a Mac OSX desktop/laptop.

You'll also want to be somewhat familiar with the Python programming language and Bluetooth low energy. The Hitchhiker's Guide to Python has a great learning python section with links to books and free resources for learning the language. For Bluetooth low energy be sure to read this excellent intro guide and even consider picking up a book on the topic.

Adafruit Library For Mac Os

When you're ready continue on to learn about what hardware you'll need to use the Bluefruit LE Python library.
