4. Hardware Design 5. Memory Map 6. GPIO Specification 7. Software 8. Extra Credit Abstract This project requires us to design a Vending Machine Controller using ARM microprocessor. The whole design works on preprogrammed specifications stored in memory location of microprocessor in form of Assembly Language. External sources are linked to the microprocessor through peripheral devices that communicate vital information to the microprocessor for the desired functioning of the vending machine. A system that links all such vending machines is also implemented, so as to keep track of transactions and current status of these machines. Output such as number of items available, should there be a refill of certain items, should there be a money collection from a full coin collector of a vending machine, and so on and so forth. Serial interface is used by operator to maintain the machine remotely.

Introduction This document is required to reflect the hardware design involved in developing the vending machine controller. The design consists of ARM Core Microprocessor, a Memory System, General Purpose I/O's (GPIO's), Universal Asynchronous Receive & Transmit's (UART's), a standard Bus architecture like AMBA which links all the hardware units together before a bus interface and external
