Hello,

I'm trying to learn how to push data to IO using my SparkFun ESP8266 Wifi Shield. To do so, I made sure to install the following libraries:

* ArduinoHttpClient (from within IDE)
* Adafruit ESP8266 (from within IDE)
* Adafruit IO Arduino (from within IDE)
* Adafruit MQTT Library (from within IDE)
* Sparkfun ESP8266 (from github link)

Then using the adafruitio_09_analog_out example file, I set up my IO account name and key, and modified the wifi settings to use the SparkFun wifi code. I tried uninstalling arduino IDE, deleting the libraries, and the reinstalling the libraries in the same way as above. When I try to compile the code, I get the following errors:

'AdafruitIO_Feed' does not name a type

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Some Googling suggests that "does not name a type" usually means I'm missing a library. Any ideas? The example code is:

Code: Select all

#include "config.h"

/************************ Example Starts Here *******************************/

// this should correspond to a pin with PWM capability
#define LED_PIN 5

// set up the 'analog' feed
AdafruitIO_Feed *analog = io.feed("analog");

void setup() {

  // start the serial connection
  Serial.begin(115200);

  // wait for serial monitor to open
  while(! Serial);

  // connect to io.adafruit.com
  Serial.print("Connecting to Adafruit IO");
  io.connect();

  // set up a message handler for the 'analog' feed.
  // the handleMessage function (defined below)
  // will be called whenever a message is

  analog->onMessage(handleMessage);

  // wait for a connection
  while(io.status() < AIO_CONNECTED) {
    Serial.print(".");
    delay(500);
  }

  // we are connected
  Serial.println();
  Serial.println(io.statusText());

}

void loop() {

  // io.run(); is required for all sketches.
  // it should always be present at the top of your loop
  // function. it keeps the client connected to

  io.run();

}

// this function is called whenever an 'analog' message

void handleMessage(AdafruitIO_Data *data) {

  // convert the data to integer
  int reading = data->toInt();

  Serial.print("received <- ");
  Serial.println(reading);
  analogWrite(LED_PIN, reading);

}

And the modified config.h code:

// or if you need your Adafruit IO key.
#define IO_USERNAME    "scada"

Update: Turns out, Arduino Uno is not compatible with Adafruit IO.
