ThingSpeak Communication Library for Particle - v1.6.0

• Updates to remove references to Twitter and associated functionality
• Bug fixes

ThingSpeak Communication Library for Particle - v2.0

Version 2.0.0

• Fixed code indentation in ThingSpeak.h
• Removed overloaded 'begin' function. The function signature does not need to include TCP port of the server
• Add readMultipleFields function.

The above function enables users to use multiple fields in the last ingested feed of a channel. The channel to be read from can be private or public. If the channel is private, user has to pass in the readAPIKey along with channel number to the readMultipleFields function.

Major advantage of using this function is that the user will not need to make multiple API calls to ThingSpeak to read different fields of a feed in a channel. The fields the can be read in a single "readMultipleFields" function invocation are:

1. Fields 1-8
2. Status
3. Latitude
4. Longitude
5. Elevation
6. createdAt timestamp (for feed)

The user has the option of reading Fields(1-8) as int, long, float or a String.

ThingSpeak Communication Library for Particle v1.5.1

Version 1.5.1

• Added support for Argon and Boron Mesh devices
• Modified examples to work with new hardware
• Removed extra \n from writeRaw
• Added begin(client, port) to support TLS

This library enables Particle hardware to write or read data to or from ThingSpeak, an open data platform for the Internet of Things with MATLAB analytics and visualization.

ThingSpeak offers free data storage and analysis of time-stamped numeric or alphanumeric data. Users can access ThingSpeak by visiting https://thingspeak.com and creating a ThingSpeak user account.

ThingSpeak stores data in channels. Channels support an unlimited number of timestamped observations (think of these as rows in a spreadsheet). Each channel has up to 8 fields (think of these as columns in a speadsheet).

Channels may be public, where anyone can see the data, or private, where only the owner and select users can read the data. Each channel has an associated Write API Key that is used to control who can write to a channel. In addition, private channels have one or more Read API Keys to control who can read from private channel. An API Key is not required to read from public channels. Each channel can have up to 8 fields. One field is created by default.

You can visualize and do online analytics of your data on ThingSpeak using the built-in version of MATLAB, or use the desktop version of MATLAB to get deeper historical insight. Visit https://www.mathworks.com/hardware-support/thingspeak.html to learn more.

ThingSpeak Communication Library for Particle v1.3.0

Version 1.3.0

• Added setCreatedAt() for setting the created-at timestamp of an update
• Added setTwitterTweet() for sending a update to twitter
• Added readStatus() for reading the status of the latest channel update
• Added readCreatedAt() for reading the created-at timestamp of the latest channel update
• Fixed an HTTP formatting problem that stopped these libraries from working with Puma
