	After calibrating the compass, the calibration status was changing at runtime due to magnetic interference from the ground and shaking of the car.		After calibrating the compass, the calibration status was changing at runtime due to magnetic interference from the ground and shaking of the car.
		+	This occurred even after turning off the auto calibration feature in CMPS14 module.

-Controller Area Network (CAN) is a communication protocol for off-board communication between various devices. The overall working of the Self driving car is completely dependent on proper CAN communication among all the control units at all times. To ensure this, there is a health monitoring system in the form of heartbeat messages which the master controller receives periodically from all the other control units. Apart from that, the CAN protocol provides appropriate speed of data transfer among all the control units for the proper functioning of the car. There is also the Message Is Absent(MIA) management facility to detect a break in communication thereby causing particular messages not being received at a certain rate when they are expected to be received, by the MIA timeout and replace their values with some safe values as configured in MIA data structures. Care has been taken to ensure that high priority messages are transmitted at a lower rate so that no message ever gets starved to get hold of the bus.

-Hot Wheels is Self Navigating RC car using CAN communication based on FreeRTOS. While navigating to the destination, if car sees any kind of obstacle, it avoids that too. The RC car takes real time inputs and covert it into the data that can be processed to monitor and control to meet the desired requirements. In this project, we aim to design and develop a self-driving car that autonomously navigates from the current location to the destination which is selected through an Android application, avoiding all the obstacles in the path. The car comprises of 5 control units communicating with each other over the CAN Bus, each having a specific functionality that helps the car to navigate to its destination successfully.
