    Thumbs up Microchip Assembly Commands

    Hello Everyone,

    For those of you who occasionally need to insert assembly into your PICBasic code, I've compiled a list of the MPLAB assembly commands and their functions onto one page as a handy reference.
    The description of each command is very brief so if you aren't familiar with Microchip's assembly language you might want to read up on it to understand it better.

    Feel free to download it and print it out.

    Nice job. I like the brief description.

    Your document will go well with this as an index.

    Default microchip assembly commands

    The following shows you which device families include which instructions.

    Mpasm Assembler User Guide
    http://ww1.microchip.com/downloads/e...Doc/33014K.pdf

    And this gives you a way to perform 8 and 16 bit compares, as well as an example of 16 bit subtraction, using assembly (in case you need it for ASM interrupts).

    There are a lot of good assembly tutorials here:

    http://www.gooligum.com.au/tut_midrange.html
    Digital I/O, switch debouncing, timer0, sleep mode, the watchdog timer,
    comparators, ADC, delay routines, relocatable code, assembler macros,
    interrupts, oscillator modes, brown-out detection, ultra low-power wake-up,
    lookup tables, 7-segment displays, multiplexing, long arithmetic, arrays and more
    Lesson 14 on indirect addressing and long integer arithmetic added 5/4/10
    Lessons 1 and 13 updated 21/3/10

    comparators, ADC, delay routines, assembler macros, relocatable code,

    Lesson 11 updated 21/3/10

    And you need Darrel's post for Macro's. Here's the link, http://www.picbasic.co.uk/forum/showthread.php?t=13195 and I have attached a PDF of it for easier printing.
