• Intro
  • Contact info
    • See here.
  • Due dates
    • Outlines and some homeworks: Monday before class.
    • Other homeworks (Section meeting): Thursday 7:30 PM
    • Demo (and hand in printed code): Saturday 5:00 PM
  • Combos to labs
    • Given or ask me for them
  • Intel processor manuals
    See here.
  • Website - things to look for
    • Latest News - Find out the updated pages.
    • References - Example code, charts, annotated code, PDFs of manuals, and more!
    • Q&A - The FAQ.
    • Tools - Where to get the compiler, assembler, etc.
• Number conversion
  • Conversion between hex/octal/binary/signed decimal/unsigned decimal
  • Two's complement
    • The leftmost bit denotes sign, 0 is postive, so signed and unsigned postive numbers have the same binary representation.
    • To negate a number, flip all bits and add 1.
    • An 8 bit signed integer can take on values from -128 to 127.
    • Notice that small negative numbers have more 1's in their binary representation than large negative numbers.
  • Check: unsigned value + abs(signed value) = 65536 for negative numbers.
  • Reminder that no calculators or computers are allowed on problem 1
• Project overview
  • RoboTrike abilities
  • Interface overview (menus)
  • Displayable characters:
    0 1 2 3 4 5 6 7 8 9 A b C c d E F H h I i J L l n o P S t U u Y - [ ] ?

• Functional specification
  • Importance
  • Go over the parts of it
    User interface, input and output sections will likely be the longest sections.
  • At least 2 pages, and completely define the system.
• Homework problem 3
  • The descriptions and functional specs ARE CORRECT. Make sure you understand them.
• Soldering
  • Clean the tip with the wet sponge OFTEN.
  • Lab policy
  • Soldering demos
• Continuity checker
  • Solder the mic after the battery clips
