Qt set-up for texas instruments AM335x ARM Cortex-A8 using linux application for an industrial scale

Abstract

[EN] In recent years, there has been a large increase of ARM based consumer products. This surge has been motivated by the efficiency and low cost of these processors, which make them appropriate for low power devices and applications that are not CPU intensive. This work examines the viability of implementing a graphical touchscreen application for an industrial scale on a Texas Instruments AM335x ARM Cortex-A development board as opposed to x86 based systems. This work also intends to serve as a general reference for implementing cross-platform applications with the Qt framework targeted to an embedded Linux system running on an AM335x based hardware. Specifically, the application to be developed is an intuitive graphical touchscreen application that interacts with a Microgram IE21 industrial scale from Microgram Instruments Española S.A. over RS-232 and a SQLite relational database for bulk product commerce by weight. Product and sales information is retrieved and stored in the database.
