In reply to Mike. As long as you add the configuration bits to your MPLAB project, they will be in the hex file. All PIC programmers (I think all, certainly all the ones we sell) will program the configuration bits from the hex file and will moan if they aren't there. To add congiguration bytes to your MPLAB project, use __CONFIG or CONFIG directives in MPLAB 8, or #pragma config in MPLAB X - there is a tool to do this in MPLAB X under Windows menu -> PIC Memory Views -> Configuration Bits. Please see another blog post on MPLAB X for more information MPLAB 8 versus MPLAB X

So If I have A compiled Pic Hex code it will have The configuration bits Already set so I don’t nee to set them when burning the Chip?

In reply to fabrica de brindes personalizados. Hi Thanks for the feedback. It is ok here in IE 8 +, perhaps you have an old browser version or a strange screen resolution.

Hello there, I believe your site could possibly be having web
browser compatibility problems. Whenever I take a look at your website in Safari, it looks fine but when opening in
Internet Explorer, it has some overlapping issues.

I just wanted to provide you with a quick heads
up! Besides that, excellent site!

The configuration bytes for PIC18F in the example are these

:020000040030CA
:1000000000270F0F0083F500FFC0FFE0FF400000C5

From the hex file description, if we omit the hex file formatting we get 16 data bytes like this
00270F0F0083F500FFC0FFE0FF400000

These are the configuration bytes from Config1L to Config7H (14 bytes). The last 2 bytes are dummies. The bottom 8 are configuration, and next 6 are lock bytes. If you look in a PIC datasheet under “Special Features of the CPU” section, you will see all the configuration bits laid out and described.
