Summary

These are useful primary documents for the class. I've annotated some of them, but not-annotated most.

Note, confusingly and annoyingly: on most browsers, clicking on the links below will not correctly load .pdf files, but will instead just throw their raw contents to the screen. You can add a plugin, or just load them externally.

The main documents:

  1. Cheat sheet of the r/pi A+ GPIO pins gpio.png.

  2. The r/pi uses the Broadcom BCM2835 chip to control the various pins sticking up on its right side. The function of these pins (and the broadcom chip more generally) is decribed in BCM2835-ARM-Peripherals.annot.PDF.

    As you will find with all hardware documents, the broadcom on has numerous errors, so always be sure to look at the errata.

  3. We are using the r/pi A+, which is a ARM1176JZF-S ARM11 chip. Confusingly, the ARM11 is actually an ARMv6 rev of the architecture: arm11.

    The general ARMv6 architecture manual (which describes the entire family of chips): armv6.annot.pdf.

    The specific ARM1176JZF-S manual (which describes specific features of the chip we are using): arm1176.pdf.

  4. We will be doing some assembly programming. The easiest hack to see how to do something in assembly is to write some equivalent C code, compile it with the arm gcc you install, and disassemble the output and examine the emitted instructions.

    For a more general view see the following documents:

    A quick reference: arm-asm-quick-ref.pdf.

    A chattier book describing assembly concepts: ARMBook.pdf.

    A thorough walk through of ARMv6 instructions: armv6-inst.pdf.

    An even more thorough walk-through of ARMv6 instructions: armv6-inst-full.pdf.
