Creation of a source text

Creation of a new text file: File/New

Saving the file: File/Save As …

Source-text writing:

;Program name: test.asm

#INCLUDE <P16F883.INC> ;DEFINITION FILE

NOP

MOVLW .25

MOVWF 0x20 ; 0x20 = first free position in the data memory

INCF 0x20

GOTO $-1

END ;END OF THE SOURCE-TEXT WRITING

Saving the file: File/Save As …

Insertion of the source text into the project

1. Project window display

2. Insertion of the source text into the project

3. Source text is inserted into the project

Desktop setup

From the View menu, select the items Watch and Output.Arrange all the windows suitably on the desktop.

Saving the desktop setup

It is possible to save the desktop setup by means of the “Create Window Set” function from the “Window” menu:

Saving the source text and the project

MPLAB-IDE distinguishes between:source text editor project editor

Source text editor and Project use independent menus for creating, opening and saving of their files:

Opening the source text: Opening the project:

Source text editor/ Project - summary

Source text editor:Only source-text writingIndicates syntactic errorsDistinguishes in color between individual columns of the writing

Saving: File/Save As… (only a text file is saved!)

Project:Starting, stopping, step-by-step operation and animation of the programDisplay of the program memory, display of the EEPROM memoryDisplay of SFRs and user registersWork with BreakpointsStopwatch – measuring the duration of a specific part of the programProgramming of a microcontroller

Saving: Project/Save Project As…

Summary of the subject matter - exercises

Create a source file named “test.asm” Save it to your working file Open the saved file and write a source text in it

according to the documentation (keep the right formatting)

Save the source text (overwrite the original version)

Summary of the subject matter - exercises

Create a new project named “test.mcp” Save the project to the working file Open the project again and insert the source text

“test.asm” in it Open the working windows: Watch, Output, Stopwatch Save the project to the working file
