Schedule

Below is a preview of our week-by-week plan for the entire quarter. There may be slight adjustments and rearrangements as we go. The schedule for the final project is set and will not change.

In the readings below, K&R refers to Kernighan and Ritchie's classic text The C Programming Language (accessible via Stanford's subscription to Safari Books Online). Nick Parlante's EssentialC is another great C reference. Please do the recommended readings before lecture for best effect!

Date	Topics/Readings
Week 1
Lecture Mon 1/9	Introduction and Welcome ( slides) Readings: A fun read on how the Raspberry Pi came to be for a taste of the adventure to come. For background, review our guides on electricity, binary/hexadecimal numbers, and the unix command line. Bookmark this collection of unix video tutorials that were prepared for CS107 students. These videos cover basic concepts, common utilities, development tools, and productivity features. I also recommend Steven Wolfram's blog post Untangling the Tale of Ada Lovelace for a nice description of Charles Babbage's and Lady Ada Lovelace's roles in developing the concept of a general-purpose computer.
Lab/assign	Lab 0: Orientation ( writeup) Please do the Lab 0 prelab preparation before coming to lab.	Assignment 0: Git oriented ( writeup)
Lecture Fri 1/13	ARM processor and architecture ( slides, code ) Read Baking Pi ( intro, lesson1, lesson2 ) and skim Carl Burch's Intro to ARM assembly. Here is a link to the VisUAL simulator demoed in lecture.
Week 2
Lecture Mon 1/16	ARM assembly and machine code ( slides, code ) Before lecture, read/skim sections A3.1-A3.4 and A3.11 from the ARM Instruction Set Architecture manual. Our one-page guide to ARM. An interactive demo of ARM immediate value encoding. A tribute to how much can be done with just an 8-bit value and barrel shifter! Enjoy Danny Cohen's article Holy Wars and a Plea for Peace on the history of little-endian vs. big-endian.
Lab/assign	Lab 1: Setup your Raspberry Pi ( writeup) Please do the Lab 1 prelab preparation before coming to lab.	Assignment 1: Implement a Larson Scanner ( writeup)
Lecture Fri 1/20	From Assembly to C ( slides, code ) Review sections A3.2 and A3.3 on conditional execution and branch instructions from the ARM Instruction Set manual Our one-page guide to ARM. Brush up on C basics (syntax, data types, operators, control structures) via your favorite C reference; sections 1-2 of Nick Parlante's EssentialC; or chapters 1, 2, and 3 of K&R. Skip content on I/O and standard libraries (we are bare metal!) Read Dennis Ritchie's account of the history of C Try out the Compiler Explorer demoed in lecture Read our guides on make and gcc
Week 3
Lecture Mon 1/23	C Pointers and Arrays ( slides, code ) Before lecture, read EssentialC chapters 3 (skip material on structures) and 6 (skip material on the heap and memory management) or K&R 5.1-5.4. C-strings are primitive compared to Java/C++ strings; take note of the manual effort required to use and pitfalls to avoid. C `volatile` can be subtle and tricky. See GeeksForGeeks advice on correct use and John Regehr's blog on what NOT to do with volatile
Lab/assign	Lab 2: Below C Level ( writeup) Prelab to prep before lab.	Assignment 2: Implement a Clock ( writeup)
Lecture Fri 1/27	C Functions ( slides, code ) Read up on C functions (Chapter 4 in K&R, or Section 4 in Essential C). Read Thinking Geek's explanation of the mechanics of local variables and stack frames. Here is the ARM reference on implementing stacks with `ldm` and `stm` and this nice explanation of LDM https://keleshev.com/ldm-my-favorite-arm-instruction/
