Shared Feeds!

You can now subscribe (and write to!) a shared feed on Adafruit IO.

Don't know what shared feeds are? Check out the sharing a feed page on Adafruit IO Basics: Feeds guide on the Adafruit Learning System: https://learn.adafruit.com/adafruit-io-basics-feeds/sharing-a-feed

Release Notes

• Add the ability to write to and/or read from a shared feed on Adafruit IO:

Example of creating a shared feed: AdafruitIO_Feed *sharedFeed = io.feed("FEED-NAME", "feed-owner");

• Cleaned up some compiler warnings (compiling verbose should have a nicer/cleaner compile)

• Added example of writing to a feed (modification of Digital_In, but for shared feeds) https://github.com/adafruit/Adafruit_IO_Arduino/tree/master/examples/adafruitio_20_shared_feed_write

• Added example of reading from a feed: https://github.com/adafruit/Adafruit_IO_Arduino/tree/master/examples/adafruitio_21_feed_read

2.7.9

Added example sketch for throwing the ESP8266 into (and bringing it out of) DeepSleep mode.

Note: DeepSleep currently works on ESP8266 Board Library Vers. >=2.4.0

2.7.7

Update library.properties

board manager scraper

2.7.6

"It's about time"

Don't have any available pins to use a RTC? Just poll the Adafruit IO Server's time feeds instead!

• Adafruit_IO_Arduino client library updated to support three types of time helpers: time/seconds, time/milliseconds, and time/ISO-8601
• Example for subscribing to all three of the feed subscriptions added to examples/adafruitio_17_time_subscribe/adafruitio_17_time_subscribe.ino

v2.7.5

• #36 Fixed Feed. get() call causing hard-reset on ESP32.

• Examples edited for compatibility with the ESP32 (due to lack of analogWrite()):

  • adafruitio_09_analog_out
  • adafruitio_13_rgb

• Added the ESP32Servo Library to adafruitio_16_servo.

• Added Read-The-Docs to reduce README.md size.

• Added TravisCI for pull requests.

Fix for Ethernet FeatherWing

This version removes the archived Adafruit Ethernet2 library as a dependency and switches to the actively maintained Arduino Ethernet Library (https://github.com/arduino-libraries/Ethernet).

Changelog:

• Adafruit Ethernet 2 -> Arduino Ethernet.
• Updated AdafruitIO_Ethernet.h to include a check for if the shield is unplugged.
• Switch MQTT Ethernet clients to only connect on port 1883 while retaining _mqtt_port as 8883 for all WiFi MQTT connections.
• Explicitly pass MQTTClient the Adafruit IO Username and Key.
• Updated project dependencies to reflect the switch to Arduino Ethernet.
• Updated documentation and links.
• Updated travis configuration to remove slowdowns caused by testing sensor-dependent sketches, only testing the core API sketches.
• Updated README to include new TravisCI build link.

v2.7.1

• Added Feed lastValue method to fetch the most recent Data record for a given feed
• Replaced incoming Data CSV parser with more robust version. It should handle any properly escaped CSV now in exchange for slightly higher memory usage.

v2.7.0

• update ssl fingerprint
• csv parsing fixes

v2.6.0

update ssl fingerprint

v2.5.0

adds esp32 support
