wolf SSL / Mbed 2 deprecated CyaSSL-Xively

CyaSSL usage example: Xively access with HTTPS

Dependencies:   EthernetInterface HTTPClient mbed-rtos LM75B mbed

Import this for FRDM-k64f: http://mbed.org/users/wolfSSL/code/CyaSSL-Xively-FRDM/

For using this example:

- Prepare mbed with Ethernet connection.

- Go to http://xively.com. Sign up, and create your channel.

- Copy "Feed ID" and "API Key" on the page to XI_FEED_ID and XI_API_KEY in xively-main.cpp.

- The demo assumes LM75B temperature sensor on Xively Jumpstart Kit board. If your board does not have it, replace tmp.read() with your own read.

- Build, download it to mbed, and you will get the result "Temp" on your Xively channel page.

- Click "Temp" to get temperature graph.

Have fun!
