16F18446 - setting baudrate for HW EUSART

Thanks, Richard :)

Re: 16F18446 - setting baudrate for HW EUSART

in reality accuracy is not always critically important, 1% or larger errors still work well in 90% of cases for tty serial transmission.
8bit generator results can be equally accurate anyway.

16F18446 - setting baudrate for HW EUSART

Thanks a lot Richard.

All your settings work like a charm :wink:

Still a question: why would one choose the 8 bit baudrate generator - seems less accurate, no?

Re: 16F18446 - setting baudrate for HW EUSART

its probably better to say

there are two baudrate clock source dividers brgh=0 ; fosc/64 and brgh=1 ; fosc/16 and
and you have the choice of 8 or 16 bit baud rate generators, so 4 options...

Re: 16F18446 - setting baudrate for HW EUSART

when you get a result like
DEFINE HSER_SPBRG 832 you realize something is very wrong since an 8 bit register can not accept that value ever

you have enabled the 16 bit baud rate generator in...

16F18446 - setting baudrate for HW EUSART

Hi All,

I had an example from Richard lately where he configured my 16F18446 HW serial's port.

I didn't pay that much attention to it...

Now that I'm looking closer on "how he did it", I...
