Bad header for pic16f1459

[jackmicro]

Hi

The supplied header that comes for the pic16f1459 is completely wrong for the fuses section. There are misspelled keys, fuses that don't exist and many fuses missing. I only have the command version of the ccs compiler so there is no application tool to edit the header file. I contacted ccs support but it has been over a week and absolutely no response. Is this the norm with them?

What can I do to solve this issue?

Thank you in advance for your reply.

I'm using the PCM 5.001

Header file:

//////// Program memory: 8192x14 Data RAM: 1008 Stack: 16

//////// C Scratch area: 77 ID Location: 8000

What's LL_DIV_16? would it be PLL_DIV_16? but the pic16f1459 doesn't even have that mode...

What's NOPMPEMB? not for the 1459....

On the other hand, for example where is FOSC? no fuse programming for oscillator mode? what?

It is obvious one doesn't match the other...

But version 5 hasn't been released. You must be in a CCS Beta group.
This forum is largely concerned about released versions.

[jackmicro]

hmmm... not sure about beta.

I bought the compiler only a couple of weeks ago. Followed the download instructions and this is the version I got.

What should I do?

[RF_Developer]

You may nto be sure about beta, but *we* are sure about beta. The current "stable" version of CCS C is 4.141. There's a big prominent button for it on CCS's download webpage: http://www.ccsinfo.com/downloads.php . They have a colour click through ad for version 5, which when clicked says:

As a comment though, the header file fuse list, is only a text list to 'remind' you what fuses exist for the device. It is not the actual fuses used.
All that has happened, is that somebody has selected the actual fuses from an editor, and gone 'cut and paste' to make the list at the top of the file, and missed the first character off the list. So PLL, became 'LL'.

Look in fuses.txt which comes with the compiler, to see how to translate CCS names to Microchip names.
Unfortunately, it is common for the header to be wrong for a couple of releases after a chip is added. Your chip has only just been added, and differs from the older chips in it's PLL configuration, so email CCS, and point this out.

On internal oscillator frequency selection, if you look at the data sheet, on this chip, it is _not_ selectable by fuses. It is software settable only. So you use "setup_oscillator" after booting.
The data sheet says:
"• Program the FOSC<2:0> bits in Configuration
Words to select the INTOSC clock source, which
will be used as the default system clock upon a
device Reset.
• Write the SCS<1:0> bits in the OSCCON register
to switch the system clock source to the internal
oscillator during run-time. See Section 5.3 “CPU
Clock Divider”for more information."
Note "during run-time".
So the speed selection is done in software, not through fuses.

In fact if the compiler is handling this right, it'll set the value for you, if you just specify tbe clock rate and internal oscillator.

Thanks guys,

I understand that the fuses section is only comments, but thought the section was created automatically when choosing the fuses for the device using the pcw tool: so the actual fuses would follow the comment section and if the comments were wrong so would the fuses.

I'll replace my compiler with the latest stable version.
Will also double check the configuration for the internal oscillator during run time.

Guess I got it wrong...

Much appreciated.

Jack

I have the beta version and the fuses.txt file is in the PICC directory in mine.
