Macros Wednesday: Lab in Burton How to solder wires How to solder wires, from Popular Mechanics How to maintain your soldering iron clean How to heat shrink wires Friday: no class (work on your project!!!) Homework #9 and its solution.	Nasm Macros new Linux commands: od (octal-dump) hexdump
Week 12 11/17	Monday Recursion and reentrancy. Reentrant programs must not modify global variables! Recursion rule: 1) stopping condition, 2) recurse on a smaller problem than one given. factorial.asm Wednesday Two programs related to the current hw assignment: driver2.c, and writeIntegerAtIndex.asm Lab in Burton: Make it work! Develop the hardware/software pairs: each hardware sensor should have an assembly language routine that either knows how to read from it, or to write to it. Friday: Presentation of working hardware Homework #10 and its Solution	the LEA instruction: an more powerful alternative to mov when loading up a vector. Section 2.1.3 of Carter's Assembly Manual on the MUL instruction (and IMUL).
Week 13 11/24	Monday: Presentation of working projects (carry over from Friday) Current homework ( binary search) recursion simulating communication with an Arduino stamp Wednesday: Thanksgiving break Friday: Thanksgiving break	Section 4.8 of Carter's Assembly Manual on recursion get time of day function all about binary search...
