Hi,

Errrr, do I detect a hint of sarcasm? (yes, of course I do)

Smile

The reasons I post such questions are:

a/ I've found that 10-15% of the time, problems are due to bugs in the compiler ...

Hi,

Sorry to drag this thread up again.

I've got the 12F629 being driven by a 32kHz crystal. With only the PIC attached to a 3V, I am finding a current draw of about 190uA.

(I know the PIC is ...

interesting

i just plopped a new 12F629 in me PICStart and uploaded some code

im using MPLAB 6.4

just before the end of the programming, MPLAB puts up a message box saying "Calibration value ...

Hi,

Thanks for watchdog trick, but as the poster above says, it is inaccurate and I do need a certain amount of accuracy.

The PIC needs to count up to 6 months (183 days) - the tolerance on this ...

Hi,

Please help before I jump out of the window...

I have a PIC12F629 running at 3V with a 32kHz watch crystal as the clock.

I simply want to put the PIC to sleep() and wake up on a timer 1 o ...

sorry, the above was supposed to be a reply to my PIC12F629 thread!

Hi,

Thanks for your ideas so far.

The application is a simple timer, it must count for a period of 6 months and then let the user know 6 months has ellapsed by flashing an LED.

During the ...

Hi,

I need to power a 12F629 running at 32kHz for at least 9 months with a CR2032 coin cell (about 200mA hour).

I believe the 629 will still run down to a 2V supply, so my question is, can I sup ...

here's the code by the way which works:

int a;

// timer 1 interrupt, triggers every 8 seconds
#int_TIMER1
TIMER1_isr() {

a++;

}

// main function
void main( ...

It seems to be working now, i am getting an 8 second interrupt which is correct.

Now how do I get the chip to wake up from sleep on a timer 1 interrupt?

Thanks

Darren

Hi,

PIC = 12F629
Clock = 32kHz crystal (LP mode)
PCM = V3.153

Using MPLAB 6.4 & simulator, I cannot get timer 1 to fire.

Here's the simple code:-

#include <12F629.h>
#use ...

Hi all,

Im going to use a PIC12LC518 running at 32kHz but still need assistance with a/ the battery type and b/ crystal selection.

There will be no other ic's, just the PIC running at 32kHz.

Superb thank you!.

(I should have looked myself but didn't think it would be posted on here).

Very Happy

ok, i'll give them a try but I can't see a justification in upgrading the compiler (i.e. a cost) if all that is required is a couple of text files!?

i bought the compiler back when it was version 2 ...
