HI

I'm have a PIC 16F628 - I think it can accommodate a program no larger than 128bytes (from data sheet) right?

In mplab - where can I find out the size of the program I have written.

Thanks.

 

i think the 128bytes you are referring is for the eeprom data of PIC16f628.

yes. I thought that is where the program you write is stored on the chip.

But anyway - how much space do I have for my program. And how do I determine how large my program is using MPLAB.

 

As GraveYard_Killer said, the 128 bytes is the EEPROM data storage, the program memory is 2048 words - this is a LOT of assembler, you can do a great deal in a couple of hundred words. It also has the advantage that's it's a single page, so you have no memory paging problems.

Couldn't tell you?, I never use it, but the *.LST created by the assembler tells you.

Thanks.

Not sure how to work it though. Do you mean go to *.lst right click it and go to properties?

Just wanted to know how huge a program had to be to actually fill the mem.

 

No, open it with Wordpad, or Notepad.

If you have to ask, then it's not a concern!

The 16F628 has twice the memory of the 16F84 it replaced, and it wasn't common to fill that.

For some reason my *.lst files have the microsoft power point viewer icon - when I double click on it locks the computer up. Works fine with notepad.

 

Just open up the .lst file from within MPLAB using the <file> <open> menu items. If you save the current project with the .lst file open it'll be there the next time you open that project. It's sometimes handy to have the .asm, .lst, and even the .inc file available in the project you're workin' on.
