This project explains how to use an FPGA or CPLD to take input from one device (an ADC) and then output appropriate signals to a motor controller IC, that provides precise control over the DC motor’s speed and direction.

Since we now know how to create PWM output with a CPLD or FPGA and we also know how to understand dynamic analog input using an A-to-D converter, we can actually combine these two functions together and create an FPGA DC motor controller!

Even though I have written many, other, motor control articles, none of them used a CPLD or FPGA as the main controller. This article will focus on explaining how to use a CPLD to take input from one device and then output appropriate signals to a motor controller IC, that will give us precise control over the DC motor’s speed and direction.
