Work in progress... I'm putting this together as you're reading this... Stay tuned for a more polished tutorial. This is a quick introduction to writing assembly language programs for the Pi.
You can find more tutorials here:
Setup
- Please refer to this page for information on how to set your system up. I'm using a Mac connected to the Pi via wifi, and ssh-ing to the it in a Terminal window.
First Program
- This example is taken from thinkingeek.com's tutorial on assembly on the Pi:
/* first.s from thinkingeek.com http://thinkingeek.com/2013/01/09/arm-assembler-raspberry-pi-chapter-1/ Defines a main function that returns 2 as an exit code. */ .global main /* 'main' must be visible by the C compiler. */ .func main /* declare 'main' as a function */ main: mov r0, #2 /* load immediate value 2 into Register r0 */ bx lr /* return 2 to Operating Sytem */
Create the program
- ssh to the Pi using the Terminal Window. Refer to [this page for how to do this].
- Use your favorite editor on the Pi (mine is emacs), create a file called first.s and enter this code. If you are interested in bypassing the editor, simply type this:
cat > first.s
- and paste the code above. Then press ENTER, Control-D, ENTER, and this should create the file for you.
