Leigh Brooks / HuxleyIntegrationAPI

API for linking to the Huxley National Rail REST proxy for the retrieval of live National Rail data. Still needs work (sadly), but works well for the time being!

Dependencies:   EthernetInterface

National Rail Huxley Integration Interface

This API provides a clear link between the National Rail Huxley Integration JSON interface (available at https://huxley.unop.uk/), and mbed devices, over an Ethernet connection. This project is still very much a work-in-progress, but hopefully I will be able to provide a comprehensive method of retrieving live National Rail departures data in a simple and effective way.
