Measurement of time delays in embedded systems with external Wi-Fi module (English)
Abstract [sv]

Studien syftar till att analysera mätningar av tidsfördröjningar i inbyggda system som använder externa Wi-Fi-moduler och Network Time Protocol (NTP) för tidssynkronisering. Mätning i detta sammanhang innebär att man tar mätbara data som kan representera tidsfördröjningarna i numerisk form, vilket gör det möjligt att analysera och jämföra dem på ett objektivt sätt. Genom en grundlig litteraturstudie identifierades de olika elementen involverade i tidssynkroniseringsprocessen, inklusive egenskaper hos Wi-Fi-moduler, NTP-protokollet och andra systemkomponenter. Insamlad data analyserades för att upptäcka mönster och tendenser i tidsfördröjning. Det övergripande målet med studien var att bidra med specifika insikter som kan förbättra konfigurationen och prestandan hos inbyggda system. Genom att jämföra prestanda hos olika dataenheter och visa på variationer i tidsfördröjning, har studien gett konkreta mätdata i form av tid, dess genomsnitt och standardavvikelse. Dessa insikter kan användas för att designa mer tillförlitliga inbyggda system med förbättrad tidssynkronisering, vilket är avgörande för mcu som kräver hög precision och stabilitet.

Abstract [en]

The study aims to analyze the measurements of time delays in embedded systems that use external Wi-Fi modules and the Network Time Protocol (NTP) for time synchronization. Measurement in this context means taking measurable data that can represent time delays in numerical form, making it possible to analyze and compare them objectively. Through a thorough literature review, the various elements involved in the time synchronization process were identified, including the characteristics of Wi-Fi modules, the NTP protocol, and other system components. Collected data were analyzed to detect patterns and trends in time delays. The overall goal of the study was to contribute specific insights that can improve the configuration and performance of embedded systems. By comparing the performance of different data units and showing variations in time delays, the study provided concrete guidelines and recommendations for engineers and developers. These insights can be used to design more reliable embedded systems with improved time synchronization, which is crucial for mcu requiring high precision and stability.
