EENG 383 Final Project
Spring 2015
Agenda
1. Overview
2. Materials
3. Schematic
4. Pseudocode
5. Timing Diagram
Overview
● Create a “sky camera” that moves in X and
Y direction around “stadium”
● Uses PuTTY interface for user control
● All motors start and stop at same time
o
Different step rates
Materials
● Actobotics
Components
● Step Motors
● EasyDriver Circuits
● Huge Protoboard
● HCS12
● Random Hardware
● Fishing Line
● Power Supply
Schematic
Pseudocode
Initialize SCI
Initialize Output Compares
Get starting coordinates
Start infinite loop:
Get coordinate to move to
Calculate change in string lengths
Calculate motor steps needed
Use output compares to drive motors
Make end coordinates the start coordinates
End
Next Steps
● Incremental testing- in progress
● Connect strings
● Final testing and debugging
