Atsuya Okazaki / Mbed 2 deprecated OAuth4Tw Featured

Sample code using OAuth library for twitter.

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

  1. Create a Twitter account if needed.
  2. Access "Twitter Developers" web site by using the account: https://dev.twitter.com/
  3. "Create a new application" in "My applications" menu. Then, fill the form with appropriate information.
  4. "(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.
  5. Note "Consumer key", "Consumer secret", "Access token", and "Access token secret" described in "Details" tab.

Set up on mbed

  1. Import the sample program
  2. Replace "Consumer key", "Consumer secret", "Access token", and "Access token secret" in main.cpp with yours.
  3. Compile the code with libraries and install the output binary into your mbed.
