8 bits, even, 1 stop bit????
Hi all, I'm new to this newsgroup, as well as to the world of the
basic stamp and it's counterparts. A friend of mine asked me if there
was any mcu's out there that would be able to send and receive serial
data in the following data bits definition: 8 DATA BITS,EVEN PARITY,1
STOP BIT at baud rates ranging from 300 to 2400 BAUDS.
I looked in the basic stamp documentation, but couldn't find
anything. It was mentioning initialization at either 8,N,1 or 7,E,1.
I am also familiar with other MCUs. I know the 68HC11 doesn't, I'm
not sure if there would be a way to write similar UART code for the
PIC16F84 or the Z8E04/08.
thanks,
E.

bits,even parity.
you can download a copy of the BS2 manual online at www.parallaxinc.com or
www.stampsinclas.com. Look under Serin or Serout for a complete baudmode
table and how the BS2 uses a 16 bit word to configure boaudmodes.

Nearly all hardware and software is set up to only transmit 8 bit
bytes of data - this means that if you want 8 data bits, there's no
place left to put a parity bit. Otherwise, you'd have to have a ninth
bit somewhere. While it would be possible to have the software or
hardware generate the ninth bit, for most simple systems like the
stamp this isn't done. So, if you want parity, you get 7 data bits +
1 parity bit.
