Cash Automation: porting and adaptation of the governing module of an automated cash recycler machine The purpose of this thesis is the porting of the RTC firmware. This thesis has been produced within the R&D department of ARCA Technologies S.r.l., the producer of these devices. In particular in Bollengo (TO), where is based a branch of the company established in Mebane, North Carolina, USA. The porting process consists in a remaking of the firmware in order to be compliant with the new hardware components. In software engineering, porting means changing a software to make it work in a computing environment different from the original one, of course the functionality of the machine controlled by the software must be the same.
