debug error on 12F509

[Bruce]

Some things (pretty much everything you're showing) just are not supported on 12-bit core.

Hello Bruce

With the 12F609 it works, the compiler not show any errors

If i add on program begin the instruction to tune the internal oscilator
the compiler show a error message, do i not need to add the
DEFINE OSCCAL_2K 1 on the begin of the code?

Thanks
Regards
Pedro

Hi Pedro,

With the 12F609 it works, the compiler not show any errors

It shouldn't show any errors. The 12F609 is a 14-bit core. The 12F509 is a 12-bit core.

do i not need to add the
DEFINE OSCCAL_2K 1 on the begin of the code?

DEFINE OSCCAL_2K 1 is for a 2K part. DEFINE OSCCAL_1K 1 would be for a 1K part, but this isn't necessary for a PIC that doesn't have a factory OSCCAL calibration value stuffed in the last program memory location or an OSCCAL register

Hello again

Thank you Bruce
The internal osc of the 12F609 is 4Mhz, right?

The 12F609 internal ocs runs at 4MHz or 8MHz. IOSCFS: Internal Oscillator Frequency Select bit in the config register is used to select 4 or 8MHz.
