Thank you. I got the same results as you and I have now found the problem.

I was using

#use DELAY(crystal=16000000)

when I changed this to:

#use DELAY(clock=16M)

H4 gets set correct ...

Thanks for all this advice. I have made progress as I can spot the byte I need to change in the hex file to set up the PLL correctly. Does anyone know how the checksum is calculated for a line in th ...

There is a 32.768Khz crystal connected, it is an ABS13. I'm not the hardware engineer, but the crystal has a slight slope at one end and it had been positioned on the board around the wrong way, i.e. ...

Just to let you know, I discovered the crystal had been been positioned the wrong way around which explains a lot! All is working now. Many thanks

Thank you for your reply. I see you have highlighted the note that you need to wait 4 secs and then set the OF to '0'. I believe I have done this with:

delay_ms(4000);
rtc_finish_osc_restart(); ...

Hi, I am using the i2C functions for the first time and am having a problem clearing the OF bit of the M41T81S rtc when the module is first booted up and it is set. Does anyone have experience of thi ...

Great. Thanks again.

Thank you PCM programmer! I am delighted to say thanks to you I have got it working now. Much appreciated. Very Happy

It is version 4.100.
