PIC10F202 OSCCAL

[Dave Squibb]

Hi all,
I need to load OSCCAL with its stored value.

Tried

Code: Select all

asm movwf OSCCAL

in a C Box
And got compiler errors:

31: __config("__PROG_CONFIG", "pic", 0x1, 0x3FEB);
^ (1386) unable to determine the semantics of the configuration setting "OSC" for register "CONFIG" (warning)
PIC10F.c: main()
74: asm movlw osccal
^ (317) "(" expected
^ (318) string expected
^ (194) ")" expected
^ (312) ";" expected
(908) exit status = 1
(908) exit status = 1

Error returned from [xc8.exe]

C:\Program Files (x86)\Flowcode\Common\Compilers\pic\batch\pic_xc8_comp.bat reported error code 1



FINISHED

Any ideas please?
Dave

OK, This seems to compile:

Code: Select all

#asm
movlw OSCCAL
#endasm

The XC8 compiler manual says "Note that this function is automatically called by the runtime start-up code (unless you
have explicitly disabled this option,( see Section 3.7.1.14 “osccal”) and you do not need
to call it to calibrate the internal oscillator."

Question: Does Flowcode 8 automatically load OSCCAL with the calibration value?

Thanks,
Dave.

Hi Dave,

We haven't explicitly disabled the osccal functionality so the compiler should be doing its thing for you and loading the calibration value.
