Thanks for the spot Martin,
Looks like they totally re-wrote the rulebook for this one. The register setup is nothing like the other chips.
Hmm I'll have a think on it.

Hi Martin,
I've had a go at editing the code. Do you have one of the chips to hand?
If you do then please can you try this and let me know how you get on.
If all ok then I'll push to the update system.
Thanks.

Hi Ben,
the baud is set to 9600
Measured baud is 38.5K
Internal Osc speed is correct @ 48MHz as UART works in software mode.
Will Test RX after TX confirmed working.

Thanks Martin,
What about this?

You're welcome.
Baud dropped to 151 bits per sec

Aha thanks, yes I see now it's missing the usual FOSC/4 for the clock input
I've changed the new baud calc so it's actually using the full 16-bit range with the FOSC clock source.
Let me know how you get on.

Hi Ben,
Thank you.
RX and TX are now working perfect.
Tested at 9600 and 38400 BPS

Hi Ben,
Something has gone wrong with pushing the update on the system.
The file you posted compiles ok.
When compile with V6.0, The following errors occur:

Thanks Martin,
I see what I did now I uploaded the wrong file! Should be fixed now.
I'll try and get onto those interrupts for you too.

Hi Ben,
Thank you
Yes UART is now working with the latest update.
