What is a microcontroller (MCU)? A microcontroller includes a microprocessor (CPU) as well as a number of other components like RAM, flash and EEPROM to store your programs and constants. While a microprocessor requires external devices to control things like input/output, or timers to implement periodic tasks, and digital to analog converters, a microcontroller is all inclusive. Contrast this all-in-one approach with a typical personal computer which contains an INTEL or AMD CPU, as well as separate chips for RAM, a separate video card, a dedicated hard drive, silicon chips or PCI circuit boards to enable the processor to access USB, serial and video card signals Microcontroller pins are general purpose, whereas CPU pins are specific. This means that each pin is tied to a multiplexer which you must set to choose the particular use for the pin. For example, in a microcontroller, one pin pin might be re-purposed for the following tasks 1. The output of a timer 2. Send a signal to a motor 3. Receive an input from a sensor or analog device

Freescale S12 C-Family Specific Device Used = APS12C128SLK Courses Developed by Fredrick M. Cady Related Textbook: Oxford University Press: Software and Hardware Engineering: Fredrick M. Cady Files: All files related to this course are at bottom of this page. Summary: Introductory level course.  Covers basic microcontroller concepts and exercises in both assembly and C programming language.  Instructor editions of the laboratory include answers to questions and additional commentary by author especially for instructors. The following is a laboratory short courses developed applying the Process Oriented Guided Inquiry Learning (POGIL) pedagogy.  POGIL uses guided inquiry – a learning cycle of exploration, concept invention and application – as the basis for many of the carefully designed materials that students use to guide them to construct new knowledge.  POGIL is a student-centered strategy; students work in small groups with individual roles to ensure that all students are fully engaged in the learning process. POGIL activities focus on core concepts and encourage a deep understanding of the course material while developing higher-order thinking skills. POGIL develops process skills such as critical thinking, problem solving, and communication through cooperation and reflection, helping students become lifelong learners and preparing them to be more competitive in a global market.
