Function doesn't return correct values?

@kidrock I just tried to create a test program that exposed a float variable and I got a compiler error. I don't think FLOAT is a supported type yet for Spark.variable().

Here's my code that didn't compile:

bool state = HIGH;
float floaty = 20.5;
void setup() {
    pinMode(D7,OUTPUT);
    digitalWrite(D7,HIGH); // turn on D7 by default
    Spark.function("test", testFunction);
    Spark.variable("floaty", &floaty, FLOAT);
}
int testFunction(String args) {
    state = !state; // toggle the state
    digitalWrite(D7,state);
    return 200;
}

You could use a string to get your data through a GET request from Spark.variable() like wgbartley has done here:

You will receive back something like this currently:

{
  "cmd": "VarReturn",
  "name": "mystr",
  "TEMPORARY_allTypes": {
    "string": "20.25",
    "uint32": 842018354,
    "number": 842018354,
    "double": null,
    "raw": "20.25"
  },
  "result": "20.25",
  "coreInfo": {
    "last_app": "foo",
    "last_heard": "2013-12-31T02:18:20.493Z",
    "connected": false,
    "deviceID": "098712304987123046761928"
  }
}

GET request formatted like this:
https://api.spark.io/v1/devices/53ff6a065067544838360587/mystr?access_token=0826376570961234796129873409817245
which works in your browser address bar, once you put a valid access_token in :wink:
