FREERTOS BASED ENVIRONMENTAL DATA ACQUISITION USING ARM CORTEX M4F CORE

Yogita Patil, Sidharth Bhatia

Abstract: In today’s decade of Big Data and complex computing, the Data acquisition systems hold a prime position. In this project, we present a Data acquisition system, which runs on ARM Cortex M4F core microcontroller and this whole system is managed by a real time operating system names FreeRTOS. Tiva C Series Launchpad is used as the board. The system is currently designed to monitor only temperature. A temperature sensor will be used for monitoring temperature. The data received will be stored in SD card. The main objective of this project is to design a data acquisition system, which is portable, cheaper and deterministic. Currently available systems in market are expensive and bulky whereas this FreeRTOS based Data acquisition system is cheaper and portable as well.
