ECE 272: Digital Logic Laboratory
The TekBots platform is used in ECE 272: Digital Logic Lab, an introductory digital design course. The platform enables opportunities that facilitate learning both combinational and simple sequential designs. These designs are implemented using a Lattice FPGA through schematic capture and Verilog. Some examples of projects are a remotely operated vehicle and a semi-intelligent autonomous robot.

Section 1: Basic Combinational Logic and the MachXO2
This section covers the basics of using the Lattice Diamond software to program an FPGA, and connecting the Lattice Breakout Kit to the button board.
Section 2: Combinational Logic (Custom Remote Control)
Design a wired remote to drive the TekBot.
Section 3: Combinational Logic (Seven Segment Driver)
Design a 7-segment display decoder.
Section 4: Modular Combinational Logic Using HDL
Improve the functionality of the remote developed in Section 2. Add an analog timing board to automatically react to bumping into an object while driving the TekBot.
Section 5: Finite State Machine Using HDL
Design a digital state machine to control the TekBot's reaction to bumping into an object.
Section 6: Final Design Project
Design a system that will measure an analog voltage on the TekBot and display it using a multi-digit 7 segment display.
