Thank you Ttelmah,
I am embarrassed to ask but where is the "code library"?

I have the pullups but no Cap so I will add that over the next few days.

Hmmmm that was easy!Embarassed
In my defence I studied the device file and saw TX2 and RX2 and thought they were the USART designation....

Joe,
I have dim memories of the Transmit Buffer Empty interrupt from long ago.

I thought it fired after the TX buffer had emptied.

It looks like your code is just waiting to run but I could be ...

I think you are confirming my read of the RTC operation.
It would have been nice to magically wake at the precise time, no such luck.

Yes I have a beacon ping to synchronise "time" acros ...

I cant see where you get the data from the RS232 port
I would also recommend an echo to test the connection

#int_RDA

char c = getc(port1);

I have a problem getting the on board RTC Alarm to operate in the manner I would like.
The project in essence is very simple. The devices are battery operated and are part of a network of over 100 d ...

Sorry for delay in getting back to you, been dragged out into the sunshine for a few days!
The datasheet PCM found is correct. I had thought I had ordered the 12.5pF device but it looks like I have t ...

PCM, what a sterling effort. If you were around here I would come and pay homage.

I have my system working and here is a note to hopefully help the community.

Jay,
Thanks for the reply.
I am using the ccs IDC so I can stay calm and relaxed with what I am doing.

I used to use MPLAB back in the days when assembler was the go but the Ccs C IDC has spoilt ...

Thanks for the speedy reply Ttelmah,
Yes I understand about the fuses but I forgot!
