Simple TMR1 application example needed

[Darrel Taylor]

Hi Roger,

It's working..

But the 16F88 defaults to 31.25khz internal oscillator.
So it takes a while to complete.

If you read it back too quick, you don't see anything.

Adding ...
    OSCCON = %01100010 ; Set Internal OSC to 4mhz.
it takes a fraction of a second to complete.

And this line overwrites the Timer results, so you might want to comment it...
Result[Ctr_A] = Ctr_A ' assign Result's index

hth,

Added:
F88's Flash memory is written in blocks of 4, so you'll need to change the length of the data.

Thanks Darrel,

After I posted my message, I added a blinky and noticed the "very slow motion".

Now I use a 20MHz crystal so I corrected the configuration fuse and added the DEFINE information.

But new problems come up...

To get the program starting, I need to approach my finger close to the xtal (?!) - it looks like some capacitance issue. I added a 10Mohms resistor in parallel with the xtal and now, the program starts everytime I power the PIC.

On the other hand, my PICKit2 programmer won't recognize my PIC when I have a 20MHz xtal intalled on the breadboard. I don't know what this comes from. Maybe one of you does?
