8/30/2016 - 0.3.0 - Major new functionality, API improvements, and bug fixes
- Added asyncronous ESP8266 support
- Added server/client networking support
- Added support for serving web pages and submitting forms
- CRITICAL: In order to use the ESP8266 web server functionality you must increase the size of the serial port buffer. In C:\Program Files (x86)\Arduino\hardware\teensy\avr\cores\teensy3\serial1.c Set TX_BUFFER_SIZE and RX_BUFFER_SIZE t0 1024
- Commands can be entered via webpage
- Added support for sending log data to internet based logging services (Loggy)
- Added support for getting holiday information from a date
- Added a general module for helping with outdoor lighting projects that need time of day support, motion sensing, and lumination sensing (lumination sensing not totally tested yet)
- Added a simple display layout module
- Support for the ILI9341 display with very fast font rendering with little to no update flicker.
- Commands can provide help information
- Added "help" command that lists all registered commands and their help message
- Improved module system to be easier to use
- Modules only take up RAM if they are included in a project
1/24/2016 - 0.2.0 - General Stabilization and API improvements
- The EmbeddedLibrary has now been deployed on two complicated systems that are used daily. (One is at https://github.com/beehoppop/FrontHouseLEDProject)
- Command system has been generalized to handle input from any source (currently a serial port and the CAN bus)
- Removed dependency on external Sparkfun library
- Brought CAN bus library back to life, commands can now be issued over the CAN bus (more testing is still needed)
- The module system now does most of the heavy lifting for saving and restoring settings from EEPROM
- Improved time change handling by providing a mechanism to register when the time has been changed
- Config vars can now be registered to leverage the existing mechanisms to set and get persistent global config settings
- Improvements to the debug output system so debug messages generating during command execution will go to the output of the command source
- Bug fixes
12/28/15/ - 0.1.0 - First pre-release
A framework for developing moderate to very complex ARM based Arduino sketches in C++. At the core of the framework is the concept of modules. All functionality is provided through modules allowing sketches to include what it needs. Each module can have the following:
- Its own EEPROM space that is managed by the framework
- Periodic updates at a specified interval
- Initialization done according to priorities to allow correct module initialization ordering
Another core concept is using events for library to sketch communication. The sketch registers event handlers to implement its unique functionality. An event handler is just a method on a C++ object. For example when a digital IO pin becomes active the user's registered event handler method is called for that pin. The framework handles the details of configuring the IO pin, managing the state, and handling debouncing.
In addition to the module and event systems this library provides the following functionality:
- Async wireless networking via the ESP8266. Webpages can be served simultaneously with acting as a client for other web services
- A unified real world time system that supports time providers such as the DS3234, understands time zones, and supports real world time based alarms and periodic time based events.
- A display module for the ILI9341 with fast font drawing for mostly flicker free single buffer drawing
- A module for computing sunrise and sunset times as well as calling event handlers for sunset and sunrise events
- Handling of commands coming over any input source in a similar fashion to linux command line tools with arguments being broken up and passed into an event handler as an array of c strings.
- A Digital IO module that handles debouncing and calling a specified event on both active and deactive events. Also supports setting an output to an active state for a specified period of time before returning to the deactive state.
- A touch module for the Teensyduino analog touch input pins.
- A simple config value module for setting and getting persistent global config data.
- A debugging facility for asserts and reporting errors to the user over the serial port or other configurable communication mechanisms
- A CANBus event handling module
- A module for the Sparkfun TSL2561 luminosity sensor
In Development:
- More thorough examples
A zip file of the library that can easily be installed as described below
Extract the contents of the zip file and place into your Documents/Arduino/libraries/ folder. Rename the enclosed folder from "EmbeddedLibrary-master" to just "EmbeddedLibrary".
An example sketch is provided and the headers files have lots of comments describing the API calls.
My development environment is as follows:
- Windows 7 64-bit
- Visual Studio 2015 Community Edition (https://www.visualstudio.com/en-us/products/visual-studio-community-vs.aspx), it's free.
- Visual Micro, also free (http://www.visualmicro.com/)
- Visual Assist X (http://www.wholetomato.com/) which is not free but well worth the $99.
- Teensyduino 3.x
I mention this because this library is relatively new and has not been tested outside of this setup.
