Most ECE departments teach computer systems using microcontrollers with microtrainers systems. This approach has two deficiencies. First, students must be in the laboratory to debug real-time code and physically connect peripherals, leaving little opportunity for extracurricular experimentation. Second, treating only the microcontroller distances the student from the ubiquitous PC and its standards.
A new approach to teaching computer systems and assembly language for sophomore electrical engineering students is being investigated at Auburn University. Due to curriculum restrictions, the sophomore level course has no formal hardware laboratory. From the outset, four issues were addressed: treating PC-related issues via the 8086 microprocessor (our traditional approach), introducing embedded systems with simple microcontrollers, including a project to add a meaningful hardware experience and providing a means for students to inexpensively program their MCU’s at home.
We selected the PIC12F675 microcontroller and the PICkitTM 1 FLASH Start Kit development board from Microchip Technology, Inc. for our microcontroller studies. Teams of students construct, code, debug and test complete design solutions at home and verify their implementation by real-time execution in class. The paintball chronograph project requires hardware and coding for both the PC and PIC12F675, focusing most of the pertinent course material into a single effort.
Course assessments show that the chronograph project was very successful and highly motivational. Hardware construction was relatively simple and easy to debug. Conducting field tests with “live ammo” in front of the entire class provided both excitement and extra motivation for the work. Also, the concepts of serial protocols and the PC serial port operation, particularly the importance of transfer timing and MCU clocking, were well appreciated.
