Circuit Diagram: The biased signal generator signal is connected to AnalogIn 1 on the Tiva C which is pin PE_2. Signal Gen and Tiva C ground is common. The two 10k resistors from a voltage divider which will halve the 3v input to give a 1.5 v bias. The signal from the signal generator will…
Here is a circuit diagram of the circuit shown in the video: This is the C program that runs on the dsPIC:
This process is made simple with Python’s subprocess module.
For a previous project involving stepper motors, I wanted the microcontroller to remember exactly where the stepper motor was even after power loss. There wasn’t enough time to attempt it then, so I thought I’d try something similar now.
