This thesis describes the development of a comprehensive embedded device for recording communication between two RS-232 bus elements. The assignment was set by a company engaged in the field of bar codes systems which also seeks means of error detection in communication during system elements development. This datalogger stores communication on a Secure Digital memory card and adds time stamps to the log and contains a user interface as well. The user interface provided for by means of a display and buttons. This paper deals with the selection of the micro-controller as well as suitable development tools and the design of software and hardware.

The main focus of the thesis is bringing the Atmel AT91SAM7S256 micro-controller with ARM core into life in liaison with the GNU ARM and OpenOCD development tools. The software is based on the author’s own conception using the Newlib and EFSL libraries.
