Overview
ABSTRACT
This article recalls the overall architecture of an acquisition and data processing chain via a microprocessor before focusing on information processing hardware and software. The microprocessor is presented in its environment, the various existing peripheral circuits (slave, interface, etc.) are described and the design of the part related to their operation is explained. The specificities of programming are then detailed: the real-time operation, as well as the importance of choice of the programming language and switch management.
