Dependencies: EthernetNetIf OAuth4Tw mbed HTTPClient
Twitter sample code using OAuth library: http://mbed.org/users/takahashim/libraries/OAuth4Tw/
By using the OAuth library, you can directly tweet without proxy services such as supertweet.net.
Set up on Twitter.com
- Create a Twitter account if needed.
- Access "Twitter Developers" web site by using the account: https://dev.twitter.com/

- "(Re)create my access token" with an appropriate "Access level." "Read and Write" is required for posting tweets. You can change the Access level in "Application Type" on "Settings" tab later.
- Note "Consumer key", "Consumer secret", "Access token", and "Access token secret" described in "Details" tab.
Set up on mbed
