please explain the basic steps of programing a pic18 microcontroller in mplab.

I have zero knowledge except for c programing, thanks!

Answer 1

Basic Steps of Programing a pic18 microcontroller in mplab.

Step1: Start MPLAB X

Step 2: Open a project by using Project Wizard.

Step 3: Choose the PIC that you want to program with. Example : PIC18FXXXX

Step 4: Choose the Active Toolsuite. For PIC18F the active tool suite is Microchip C18 Tool suite. If the assembler , linker, C Compiler and libririan is in the Toolsuite Contents, then proceed to the next button.

If it is not click Browse C: ->MCC18 :-> mpasm ->MPASMWIN.exe. this is for assembler toolsuite.Every toolsuite is found at MCC18

Step 5: Create a folder or a file, so that you can save your work in to that file.Ex: Testing Folder

Step 6 : Then Create a source file. The source file must be in .c format if you are using C Compiler.

Step 7: Create a Linker Script. i.e. Right click on the Linker Script, choose add files: C->MCC18->lkr->18FXXX .lkr

Now you can write your program in to the editor.

Step 8 : Is to add the files in directories at the build options. Click Project -> build options-> project -> shows the directories for:

in the directory, there are three parts we need to add file in , which are: Include Search path, library search path and linker script search path.

All the files we need to add in can be found in MCC18 file.

Step 9: Last step is to click the build function. if it is build successfully the .hex file will automatically generate in the testing folder.

Hex file is a file format for conveying binary information for programming PIC
