Debug Board Communication Interface

Abstract: The Recommended Standard-232 (RS-232) have for decades ruled in the world of computing. Peripherals such as printers have been connected to Personal Computers (PC) via RS-232 it was not only used between PC and peripherals but even for Modems. Now the era of that interface is over and a newer, faster technique has come to light. The Universal Serial Bus (USB). The USB is a Universal Bus indicating that it is able to work on any PC with any Operative System (OS). We have upgraded a debug board that is used for debugging various Device Under Test (DUT). The board now includes USB interface between the PC and board instead of RS-232. Our task is to upgrade drivers for the USB connector, program the components on the board such as the Microcontroller (MCU) so we can transfer data from PC through the debug board and out to the DUTs. When the work is done the board will be able to debug other Ericsson devices by sending different commands from the PC, these commands are sent via the Graphical User Interface (GUI) that we have developed for the debug board. We will also be able to listen and record the data coming from the DUTs
