Dear friends,

Thank you very very much for spending so much of your time in my problem.

Yes, Ckielstra is right, I use a 32768 Hz (32,768kHz) crystal for having much lower power consumption.
I ...

Dear friends,

OK, I will post the complete program, but first one other thing.
When I have a look to the clock signal with a scope then the 4.0 MHz crystal has a nice sine form. The 32768 kHz cry ...

Hi,

Yes, I use 39pF each as C4 and C5 on PicDem2, that should be ok.

Best regards

Hi,

Thanks for help, I will try it out.

Is there any special to know for using 32768 kHz crystal?
It looks so different to the others. It's not the usual form, it's round.

Please help.

Hello Neutone,

edi specifies Xtal = 20MHz
That means that in 1 mS there are 5000 instruction cycles. Vectoring to an interupt take ~100 insctuction cycles. That means that 2% of total processor ti ...

Hello Neutone,
I would like to understand the problematic nature of a timer.
In your code I can see, that the isr will be called every millisecond.
Is the performance ok? Is there also enough time ...

Hello Neutone,
Unbelievable, you give the answer before I can ask the question. Go on!!! Very Happy

Hello Gast,
I think your customer is right.

For Example:

int nTemp = 0xC0;
printf("%2X", nTemp);

In this case the uart will send 1 byte for the 'C' and 1 byte for the '0'. ...

Hello chava,
If the program is finished, remove the 'ICD=True' behind the #device command and make a final compile of your code. Then program the PIC and you will have full access to the pins B4...B ...
