DETAILED COURSE TOPICS

Week 1: Microcontrollers.  8051 pinout and electrical characteristics.

Week 2: Connecting to external RAM and program.  Latches and demultiplexors.

Week 3: Ports.  Onboard special functions – interrupts, timers, serial I/O.

Week 4: Special functions continued.  Timing analysis.

Week 5: 8051 assembly programming, emulators.

Week 6: Introduction to a typical microprocessor - 8086. Basic 8086 control signals - DEN, DTR. Bi-directional bus drivers.  8224 clock circuit.

Week 7: 2- and 4-byte bus systems.  Interrupt structure and the 8259 Interrupt Controller. Priority interrupt systems

Week 8: Finish 8259.  DMA.

Week 9: DMA.

Week 10: Multibus structure. Disk controllers - 8289.

 

COMPUTER USAGE: Students use PCs to assemble and emulate programs before burning into E/EPROMs. Students use device programmers to generate 2764/2864 program chips for their projects.

COURSE OBJECTIVES: When a student completes this course, s/he should be able to:

 

  1. Design an embedded system, including both hardware and software.
  2. Decide what level of sophistication the microprocessor needs to have and what additional devices are needed based on the features of the application.
  3. Determine how to connect the microprocessor, memories, and extra devices into a working system.
  4. Read device-timing diagrams for processors, memories, and the like, and determine device timing compatibility.
  5. Read device data sheets and pinout descriptions and understand how to wire the devices together.
  6. Build an embedded system, both hardware and software, using DMA and/or interrupts.
  7. Understand how to use auxiliary circuits, like latches, bus drivers and demultiplexors, to build a system.
  8. Understand how to use UARTS, DAC/ADC devices, serial devices, timer/counter devices and similar devices.
  9. Design the software and coordinate the software and the hardware into an integrated working system.
