Ion Systems / Mbed 2 deprecated Chipin_Main

The MBED firmware used on the Chipin sorter, developed over 12 weeks for a 3rd year university systems project. Chipin is a token sorter, it sorts tokens by colours and dispenses them to order through an online booking system and card reader. This program interfaces with an FPGA, PC and LCD screen to control the sorter. The sorter has an operation mode where it can process orders when a card is entered into the machine. There is also a maintenance mode where the device responds to maintenance instructions such as 'dispense all'. More information at http://www.ionsystems.uk/
