Assembly Language Programming

Useful Links for the Assembly Language Programming Class

ARM7 Links

• Dr. Aamodt's Assembly Language Web Page

• Another text in html format.
• The ARM Instruction Set, a good reference work.
• Knaggs and Welsh (2008 Edition).
• ARM Instruction Set Quick Finder
• ARM Instructions Quick Reference Card

• LPC214x Reference Manual This guide is immensely useful for programming the peripherals.
• ARM Compiler Toolchain Reference Manual
• ARM Reference Manual Section A of this manual is the most use.

Raspberry Pi

Depending on the version, your pi may use ARM6 or ARM7. There is actually quite a lot of good assembly language information for programming the raspberry pi.

• This document shows how to use gnu tools from the command line (even over ssh if you have no display handy) and then how to use the Code::Blocks IDE for Raspberry Pi Assembly programming. This also seems to apply to the Odroid C1 board running Ubuntu and probably other Odroid boards as well.

• A large and comprehensive set of lab experiments and code....
• Assembler, Linker, and Loader
• Gustavo Litovsky's great set of tutorials on the MSP430 Pick the latest one. There is some good information on using peripherals, though all in C.

  • Solutions to odd problems in Davies' book
  • Example Code from Davies' book ported to Code Composer Studio

Toolchain

• Code Composer Studio 6 for MSP430 User's Guide At this point CCS will work with Linux and Windows, but is not available for OS X.
  • To install CCSV6.1 on Ubuntu 15.04, you need to

$ unset JAVA_TOOL_OPTIONS 

before running the installer. There is some more information for Linux installs here. I also found out that installing Grace from the App Center makes the App Center blank thereafter, unless you reinstall CCSV6.1.

• Assembly Language Tools This manual also has some good data on the linker, including the section "Using Linker Symbols in C/C++ Applications".
• MSP430 Optimizing C/C++ Compiler (See Section 6.5 and following for how to mix C/C++ and Assembly. It is really best to read the entire chapter though, as it is all pertinent to mixing C and Assembly. It will also help you if you want to program in C, as it tells how the C compiler uses the memory, the stack, the registers, etc., and once you understand the processor as you learn to do when you learn its assembly language, it is very interesting to see how that all works in C.)
• TI Cloud Tools This includes CCS Cloud which allows you to compile and flash, but not debug. This is a partial solution to the problem that Code Composer Studio is not available natively on OS X.
• OS X Native Toolchain Installer

GCC Compiler

• Some notes on getting the GCC compiler to work with the CC3100....
• An Example of Assembly with the GCC Compiler

  • [https://e2e.ti.com/support/microcontrollers/msp430/f/166/p/294330/1026499 Some notes on porting MSP430G2553 code to the MSP430F5529. Note: There are differences in the following:
    • The F5xxx has USB and a bunch more features.
    • A TI App Note on the differences between the 5xxx and the previous ones.
    • The F5xxx doesn't have PxSEL2, and the PxSEL need to be adjusted because of different pinouts. I find pages 25-28 of the F5529 Launchpad Manual useful for these conversions.
    • The PMM (Power Management Module), particualarly the Digitally Controlled Oscillator (DCO) and Frequency Locked Loop (FLL) of the clock system is significantly different.
    • The USCI (UART, SPI and I2C serial communications) Interrupts have been consolidated. For example see section 39.3.15 of the F5xxx User Guide.

2014 Robot Information

• HSR-1425CR Continuous Rotation Servo Datasheet
• Schematics These are rather crude schematics of the robot circuit board. There are two cuts and jumps that are not reflected, at least on the last one. The effect is to change the photo transistors from a common emitter to a common collector configuration. You can see the change scratched in just below the word Fairchild on the hand drawn schematic. Basically the resistor and photo transistor are reversed in order. I believe both photo transistors are swapped to common collector configuration.
