THE MICROCHIP ASSEMBLY LANGUAGE

Introduction

The Microchip assembly language is provided by the manufacturer of the PIC µControllers.
Some highlights of the Microchip assembly language:

• Just 35 different instructions to learn.
• Loads of example programs available on the internet.
• Free compiler MPASM (comes with MPLAB).
• Free simulation tool MPLAB.
• The language can be used for all Microchip 12xx, 16xx and 17xx devices.

The best way to learn the language is by studying example programs. Most programmers use comments (text after the ' ;' ) to clarify their program.
I recommend this tutorial (pdf, 547kB) I once found on the internet (author unknown) to get aqainted to the language.
Just look into the program "LEDSRUN" (use notepad), which I also use to demonstrate the programmer, to see what the language looks like.

You can simulate your programs with MPLAB, you can find a description of this tool on the main page.
