I am a beginner and I want to convert the following program to HEX file and then send it to PIC16F877 . Please can anyone guide and help.

Download and install MPLAB from MicroChip, and use either that, or the standalone assembler MPASM to asemble the code.

Try to learn CCS C compiler or MPLab compiler...This can convert the source code to Hex code. It will give you the complete idea....

hi,
The program listing is full of errors, lots of typo's.!

Ive tidied up the program, removed the errors and it now assembles

As suggested goto: Microchip Technology Inc. - a Leading Provider of Microcontroller and Analog Semiconductors and download the MPLAB IDE V8.0

I have MPLAB IDE 8.30 and also i got the PICKIT2 . Could u please guide how to compile it in MPLAB, if you could give me the steps for proceeding further, that will be very much appreciated. Thank you for fixing my errors . Please help me further toooo.

I have used MPASMWIN , from the MPLAB software i downloaded to convert to HEX file. It is giving me errors :

Error in parameter "and" , "documents and settings"

basically its not reading the source file from my desktop. What should i do to fix it ?

Uninstall and reinstall it. Run the wizard when setting up a project.

hi,
I have noticed that MPLAB struggles with long file addresses.

Create a newfolder on the 'C' Hard Drive, call it say MyAsm1 and move the asm file from the desktop to that folder.

Also use the MPLAB Project/Project Wizard,, when doing that point the Wizard to MyAsm1 folder and you should be OK.

I did as u said eric , so it created three files one of 1Kb , other of 23 Kb and one has extension .mcs
The problem is there is no hex file found but i could see asm code when i open the 23 kb file as the source file

Also i right clicked the my1.asm file and assemble in the project , and it said "build succeeded " . And there are three new files in the folder that i created .err , .LST, and .o files

How do i proceed from here now.

hi,
By using the 'Build ALL ' option and getting a build succeed you should have a *.hex file.?
To check use 'View'/ Program Memory the hex file should be displayed.

olympus123456 · 22nd May 2009, 01:32 PM

Yes, it is displaying when i went to program memory. Its a relieve though after sooo much of writing the code and you fixing it. Really , patience is the key.

Okay good news got ittttt. Hex file is there. Now, how do i send it to the PIC, I have bought PICKIT2.

hi,
Select the PICKIT2 programmer from thr MPLAB Programmer/'select programmer'
also ensure that 'RELEASE' is displayed near the top menu not debug.

Now you are on your own, I dont use that version of programmer,, good luck.

Yes, keep short filenames, directory names, and reasonably close to the root directory.

MicroChip seem stuck back in DOS and 16 bit Windows file systems.
