ECE 5780 - Embedded Systems Design - Labs
Digital Lab Equipment Documentation and Tutorials
Project: Microcontroller Design
Students will design simple systems using a Motorola HC(S)12 microcontroller and peripheral hardware. Labs include designing a keypad interface, a thread scheduler, a simple serial network, pulse generator, and a DC motor controller that utilizes a 4-bit DAC.
This course starts with identification and control of DC motors on a prototyping platform. Then the control of stepper and induction motor is presented. Finally the class is completed with a student project for controlling a Brushless DC motor. This course has cross-over with the embedded system courses by providing a platform similar to embedded motor lab.
