Help with RTCC Module - 18F26J50

[Aussie Barry]

Thanks Henrik and Richard for responding to my post so quickly.

Henrik - your speculation and my speculation differ. Thanks for offering an opinion.

Richard - I set the T1CON register that way on purpose BUT, I also tried your suggestion. Neither fixed the problem

My plan now is to cut my losses and go to a new design using an I2C RTCC with a PIC16F1828.
I will keep you all posted on my progress.

Cheers

maybe its a mistake to set the !T1SYNC bit.
I notice the example code does not set that bit.
one thing is for sure the Timer1 oscillator will not run if its not enabled ,after that its all guess work for me

how is the 32k signal coupled to the t1clk ?

if I recall correctly to sync the t1osc with the ext signal the coupling needs to be a capacitive
one . try about .01uF
make sure the other xtal pin is not loaded up either, or you may need to drive that pin too
can't remember.
why not just put a rock on it anyway, there're cheap

google up using tcxo with pic to get some better info
