18F25K20

Hi,
I need to get a support file for the 18F25K20, and was wondering if any new support files are available. If not is it hard to create one for a new part ?
Thanks

Hi,
Thanks for the link. I installed the 18F25K20 library, and I get a error in the
utils.bas file I am linking in stating Identifier not declared for CMCON
I think it may be suppose to be named CM1CON0 or CM2CON0 but I want to clarify this before I manually change it.
Thanks

No modules have been tested against these devices - the download only provides the definition files so that you can compile. Without looking at the datasheet, it sounds like you need to manually edit...

Hi David:
I have an application running in a 18f2520. I downloaded the 18F25K20 inc file,and try to compile for the K, but it shows the following errors:
[Error] utils.bas(446):left side cannot be assigned to
[Error] utils.bas(446):Identifier not declared: CMCON
I was including SetAllDigital(), to disable ADC and comparators, so I eliminate it, to avoid the call to the offending lines and did set all digital directly, but the compiler still calls the now not included utils.bas routine,showing the same error...
Do you can help ,please...?
Thanks in advance...

If you want to use the utils module, you will need to edit the SetAllDigital() routine to support your device - else remove the include completely.

Hi David:
I did remove the include file, and still was opened by the compiler.(???).
Then I added the all digital configuration:
// SetAllDigital() FOR THE 18F25K20
CM1CON0 = 0
CM2CON0 = 0
ansel = 0
ANSELH = 0
OSCCON = $60 // INTERNAL OSC AT 8 MHZ
OSCTUNE.6 = 1 // ENABLE PLL
and it works OK. I did compile and run the application OK.
I am very happy...
Thanks again...

Hi, what exactly I have to declare that way, so the PIC18F25K20 to use internal OSC with PLL for CLOCK=64 MHz?

Lots of the system designators ('OSC', for example) differ in the K series PICs from others in the PIC18 line. You'll need to adapt your code to suit.

Also, it's 'FOSC'

Read those specs! Pay attention and you'll do fine.
