| Kurzbeschreibung | This course will teach the basics of digital electronics, to give students hands-on experience with using COTS (Commodity Off The Shelf) components to build their own systems. It covers embedded microcontroller programming, logic design on FPGAs, PCB design and assembly. |
| Lernziel | The basic aim is to remove the fear of starting and offer the students a first experience at many levels of design. |
| Inhalt | The course consists of short lectures on theory and exercises using two different hardware platforms - a microcontroller board with Universal Serial Bus (USB) interface, and a Field Programmable Gate Array (FPGA) board. In addition the course includes exercises in printed circuit board (PCB) design and PCB surface mount assembly. Students will complete a project of their own design which they can take with them after the course ends. Week 1 Lecture: Introduction and organization Microcontroller architectures and programming Architecture (registers and hardware) Reading a datasheet Demonstration of programming and using Exercise: Install USB board IDE and compiler, compile and run Blink LED program. Start to design, program, and compile a chaotic attractor to control the PWM output to modulate the LED in an analog, random manner. Week 2 Lecture: Data Converters Analog to Digital (ADC) - flash, single slope, sigma-delta Digital to Analog (DAC) Time to Digital Exercise: Use the ADC to convert an analog input and display value using LED brightness as output Week 3 Lecture: USB interfacing to PC using USB library Exercise: Continue ADC project to send values to PC for display Week 4 Lecture: PCB design PCB schematics / gate symbols PCB footprints Power supply decoupling / separation Power planes PCB design continued Optocouplers Power supplies Decoupling Components Exercise: Start to design daughterboard for AVR32 which adds analog components. Draw schematic of daughterboard. Week 5 Lecture: Binary representations of numbers Binary arithmetic 2s complement notation for signed binary numbers Binary addition/subtraction Parity Gray codes Floating point representation Exercise: Make footprints / symbols for PCB parts. Start PCB daughterboard layout. Week 6 Lecture: Boolean logic NOT AND OR Venn diagrams de Morgan's theorems - exchange AND/OR, complement each term, complement whole Canonical forms - minterm (sum of products, AND-OR), maxterm (product of sums, OR-AND) Truth tables Karnaugh maps and optimization of combinational logic Exercise: Finish PCB layout and design check. PCB panel assembled and sent for fabrication. Parts list ready for order. Week 7 Lecture: Sequential logic with state machines Representation of states and state transitions, state transition actions Exercise: Install FPGA tools, synthesize and run example Week 8 Lecture: Introduction to using reconfigurable logic (FPGAs, CPLDs, etc) Introduction to HDLs Exercise: Another FPGA example. PCBs back from fabrication. Week 9 Lecture: Logic Circuits Clocks / clock distribution / one shots Latches / Flip flops- SR, D, level sensitive, edge triggered, master/slave, clocked / un-clocked Shift registers Ring oscillator Counters - ripple, Johnson Adders Multipliers Exercise: HDL exercise - design a wiggling light bar Week 10 Lecture: Logic analog circuits PLLs/DLLs = Phase locked loops, Delay locked loops LVDS tranceivers Level converters, low to high and high to low Timing diagrams Exercise: Soldering PCBs Week 11 Lecture: Memory - SRAM, DRAM, embedded Exercise: Soldering PCBs, testing PCB projects Week 12 Testing projects Week 13 Project demos from students |
| Voraussetzungen / Besonderes | The course is meant to complement the analog course by teaching how to build systems that convert and process analog information. Students should have taken Analog Electronics for Physicists or equivalent and should have had some programming experience, preferably with C. Students (or at least each group of 2 / 3 students) need a laptop computer, preferably Windows or Linux. Windows (real or virtual) is required for the FPGA part of the course. |
