PIC32 and ASM

[DominusDRR]

Hi.

Can anyone tell me where I can learn how to program the PIC32 microcontroller assembly language?

I prefer to do it by MPLAB X.

Thanks

Have you read the documentation for that uC?  It might have an instruction reference..

It's a MIPS core.  A lot of relatively recent "how to program in assembly language" and "computer architecture" classes have been based on MIPS. (after all, it originated in Academia.)

The MPLabX uses the gnu assembler, which has a lot of features independent of the target cpu, so learning any other gnu-as (gas) target may be useful.  (alas, gas is not a particularly user-oriented assembler :-( )

If you're familiar with assembly for some other architecture, you can go to ImgTec's website and download "MIPS Architecture For Programmers", volumes 1-3. The book "See MIPS Run" by Dominic Sweetman is a thorough coverage of the architecture, though it also covers a lot of things not relevant for microcontrollers. And as westfw said, a lot of academic courses use MIPS as example.

You missed a sign on the 14th line, 3rd term.

Read the instruction set reference and do not forget that a MIPS processor also executes the instruction after a jump before making the jump. Very annoying.

ImgTec just released R6 of the architecture, and it actually removes the delay slot, among many other compatibility-breaking changes.

Do you have an link to those three volumes?, I was looking around, but could not find much?

You can find them on ImgTec's website, but you may have to register first.

ah, thanks!

I wrote assembler for the Open Source RTOS Q-Kernel. I would not recommend it is difficult to optimize the pipeline for the MIPS processor. Most C compilers generate code that performs better than assembler. If you want to try it anyway I would recommend the book from Morgan Kaufmann See.MIPS.Run

Got any more of them long haired books, boy?

LOL..    Great Show!

Assembly ain't that complicated. Heck that picture probably represents .NET
