SEROUT is not working!

[jhorsburgh]

Hey Skimask,
I am using MicroCode Studio Compiler and WinPIC PIC Programmer.
I have just changed that statement to <code>@ DEVICE PIC12f629, INTRC_OSC_NOCLKOUT</code> which is what i wanted but it still does not work.

Thanks,
Jeremy

The program makes it to thr HIT: label and turns on the LED? correct?

Are you using hyperterminal at the PC? And it is not receiving anything or is it receiving junk.

If junk, it may be the internal OSC is not good enough.

Hi Dave,
The program makes it to the HIT routine and turns the LED on, it even sends a pulse out GPIO.2 but Hyperterminal doesn't receive anything. I'll try an external oscillator to see if that helps.

Thanks Guys,
Jeremy

Hi Guys,
The external oscillator has fixed the problem! Thanks a bunch guys.

Just a thought for you...
Since you know it works with an external oscillator and NOT with the internal one which likely needs to be calibrated...Now might be the time to learn how to calibrate it to work correctly for future uses in this arena...since you've got a working example that is...

And I don't know about the WINPIC programmer, but the PICKIT2 from Microchip has an option to get the CAL value back on these types of PICs...something else to think about...

Here is the link to an00250 from microchip, regarding how to recover the missing number:

Thanks guys, i didn't realise you could calibrate the internal oscillator, ill definitely have a look into it.
