Dreamforce 2014 Workshop Exercise - RFID Case Generator
Fork of df-2014-workshop-rfid-case-generator-k64f by
This code demonstrates how to use the mbed platform with a ID-12LA RFID reader and a Freescale K64F to get data into the SalesForce cloud.
This project was generated as a workshop for DreamForce 2014..
The 2014 DreamForce workshop centers around an example scenario where you, as a street light technician, will "check in" to a given street light to service it. The street lights in this example are intelligent - they are connected, have knowledge about who/what they are, and in this example, contain an RFID sensor to allow technicians to "check in" during a service event.
The purpose of the workshop exercise is to provide exposure to new developers that the mbed IDE and development environment/ecosystem is very simple and easy to setup and use. Additionally, the workshop highlights that mbed devices can directly interact with SalesForce. The slides for the workshop can be found here.
For more information about the mbed SalesForce Interface API and its use, please see: http://developer.mbed.org/teams/MBED_DEMOS/code/SalesforceInterface/
For the workshop the mbed team designed breakout boards to connect the ID12LA to the Freescale K64F for ease of use. Pictures of the boards can be found below. If you are interested in the breakout board you can order one from the OSHPark project page or use the eagle or gerber files as you see fit.
The ID-12LA sockets onto the RFID Brekout Board which then is put onto the Freescale K64F.
