Abstract [en]

University. The purpose of this work was to examine the possibility to replace an older serial interface to a computer by the newer Universal Serial Bus (USB).

The report describe in detail the theory behind communication between a computer and a USB device, everything from signaling to data transfer. It mainly describes how USB handle a mass storage device connected to a computer. It also handles the possibility to implement a mass storage device and use the Universal Serial Bus with a small 8-bit microcontroller from Microchip.

The implementation has been made on a data logger, a small device which task is to measure the temperature with a specified interval over a longer time and store it into a memory. The thesis work has been carried out at Eltex Of Sweden in Älmhult, Sweden.

Abstract [sv]

Denna tekniska rapport behandlar mitt slutliga examensarbete på data- elektroingenjör vid Linköpings universitet. Syftet med examensarbetet har varit att undersöka möjligheten att ersätta ett seriellt gränssnitt till datorn med ett USB (Universal Serial Bus) gränssnitt.

Rapporten beskriver i detalj teorin om hur en dator kommunicerar med en enhet via USB bussen och hur signalering och dataöverföring hanteras. USB-protokollet beskrivs med inriktning mot hur en masslagringsenhet använder bussen som överföringskanal. Den beskriver också hur man enkelt kan implementera en masslagringsenhet som använder bussen med hjälp av en microcontroller från Microchip.

Implementeringen är gjord på en datalogger vars uppgift är att logga temperatur. Arbetet är genomfört på Eltex Of Sweden i Älmhult.
