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.
