Interfacing ChefBot sensors with Tiva C LaunchPad

We have discussed interfacing of individual sensors that we are going to use in ChefBot. In this section, we will discuss how to integrate sensors into the Launchpad board. The Energia code to program Tiva C LaunchPad is available on the cloned files at GitHub. The connection diagram of Tiva C LaunchPad with sensors is as follows. From this figure, we get to know how the sensors are interconnected with Launchpad:

M1 and M2 are two differential drive motors that we are using in this robot. The motors we are going to use here is DC Geared motor with an encoder from Pololu. The motor terminals are connected to the VNH2SP30 motor driver from Pololu. One of the motors is connected in reverse polarity because in differential steering, one motor rotates opposite to the other. If we send the same control signal to both the motors, each motor will rotate in the opposite direction. To avoid this condition, we will...
