“…Within an ECE curriculum, microcontrollers can be applied in digital and computer courses, introductory courses, signal processing and controls courses, robotics courses and capstone design courses. Parten 1 emphasizes the importance of microprocessor education to ECE students that first take a formal course on microprocessors followed by a design projects course where the focus is the application of microprocessors in embedded systems. Microcontrollers also find their way into various robotics courses 2 and design contests such as the Trinity Firefighting Home Robot Contests 3 and the IEEE Region 3 Student Hardware Contest 4 .…”

A controller board inspired by the Handy Board, but based on a pair of Atmel ATmega128's, is discussed. Elements of the hardware design and input/output interfaces are detailed, including parallel and serial I/O, analog I/O, an LCD interface, and dc motor control interfaces. Firmware for hardware drivers written in AVR assembly language and a handshaking protocol for communications between the microcontrollers are also discussed.The new controller board, designated Koios I, will first be used in our freshman introductory course -in lieu of the Handy Board -which involves learning about electrical and computer engineering through the design and control of robots. Koios I will also be used in our microcontrollers application course, in our senior capstone design course, and in independent research courses requiring a dedicated computer/controller.Like the Handy Board, Koios I is being developed in an open-source manner. Schematics and firmware code listings are readily available on the web. The firmware for Koios I is written in AVR assembly language; however, user applications can be written in either assembly language or the C programming language via an AVR port of the open source C complier gcc.Printed-circuit board layouts using surface mount devices are currently in progress; the results of which will be made available in the same manner as the schematics and code. Koios I is intended to be continually evolving and a USB interface for program download and an integrated development environment are planned for the near future.

The current trend in microcontroller courses is to use demonstration circuit boards with many built-in devices that showcase the input-output capabilities of a state-of-the-art device. Current microcontrollers have fifty pins or more, come in surface mountable packages and have external clock sources. The combination of many interesting peripherals and a complex processor appear to serve the immediate needs of the introductory microprocessor course. Students who chose to use a microcontroller in a future project were forced to design circuit boards requiring fabrication and assembly at outside vendors at considerable cost; this tended to discourage their use in our capstone projects course. We discuss our current introductory course that uses a MC9S08QG8/4 microcontroller from Freescale. It comes in a sixteen pin DIP package, has an internal clock and can be programmed using the same Codewarrior software IDE Freescale uses for all of its microcontrollers and can be programmed through a USBSPYDER08∀interface. We developed a set of four simple input/output boards so students can exercise their ability to interface with pushbuttons, LCD displays, seven segment displays, keypads and the serial port among other things. As with more complex boards, they gain experience developing firmware in both assembler and C languages and learn all the basic attributes of a microprocessor. We will show how students were more likely to use these microcontrollers in their capstone projects compared to previous years where more complex controllers were used. Using simpler, applications oriented boards and more lab friendly MPU devices we met our goal of having students actually want to use these devices.
