In this book, we will explain about data processing with microcontroller in the Excavator Visualization Assistant System subsystems. Design Excavator Visualization Assistant "EVA" System is designed using IMU and compass sensors to take angle data on body, arm, boom, and bucket of excavator and then the data is processed using a microcontroller so that it can be sent to display systems processed using SBC RaspberryPi to display excavator movements and bucket distance information to the safe zone according to user input. Data processing for each sensor is processed with Arduino Nano in sensor subsystem and sent to the main controller using serial RS485 communication and reprocessed again using Arduino nano as a master that receives 4 sensor data. Data processing on the sensor subsystem is with a median filtering to get more perfect movement and sent in 1 data packet containing 4 bytes. Data processing on the main controller are checking, selecting, and validation data packets using the checksum algorithm from multiplexer to be forwarded to the Single Computer Board to be processed into an excavator animation. The display user interface is designed with the view delegate model paradigm and is displayed on a 7 inch monitor.
