Data Acquisition System using a CIAA-Safety

This paper presents the analysis, design, development and implementation of a data acquisition system from various sensors, to be installed and used in different FAA Air Vehicles, through an ARM® Cortex®-R4F CPU microcontroller that meets critical safety standards, such as IEC 61508 , ISO 26262 and DO-178 (at the Software level). The sensors are: a GNSS (Global Navigation Satellite System), an IMU (Inertial Measurement Unit) and atmospheric pressure and temperature sensors. The ARM microcontroller was mounted on a development board called CIAA-Safety and its programming was carried out under the BAREMETAL format, that is, without a Real Time Operating System
