ISRRX Defaults

Hi,
Does anyone know what the defaults are when you set the baud rate ?
By this I mean is it N,8,1 and if so can it be changed for parity and stop bits ?
Thanks

Here is my Init code
ISRRX.Initialize // init the ISRRX module!
USART.SetBaudrate(br4800)

The EUSART module defaults to 8N1.

There isn't a whole lot of configuration available.. 9-bit mode will cost you the parity bit, that's about all you can do.

Yeh, the EUSART hardware in the 18F doesn't have many features...about the only thing you can change is the selection of using 8 or 9 bits. You can use those bits for anything you like, such as parity or an additional stop bit, but you'll have to do it all in software.

You can do 7+parity+stop bits, 8+parity+1stop, 8+2 stop, but you can't do 8+parity+2stop without doing the second stop bit purely as a software delay, or perhaps using a timer.

The USART.bas module doesn't support anything other than N81, so you'd have to add in any new functionality.
