... I could manipulate bits and bytes of the microcontroller. Assembly language is a low level language and is very difficult to learn and understand, therefore I had to carefully plan my code and go through various stages of planning to get to my final piece of code. I will show you how I got to the final piece of code through various stages. Diagram of 8051 Microcontroller This is a diagram of the 8051 microcontroller that we are using for the robot. You can see the various connections that are going to be made to the controller. The two stepper motors are connected to various pins from P1.0 to P1.7, each pin is connected to a different coil on the stepper motor. Each pin is connected to different coils so we can energise each one at different times, which will move the motor. I will explain this in greater detail later. Connections P1.0: MOTOR ...
