serial speed

Hi folks,

in fact I am about to join the arduino community.

But it depends on the following: is it possible to read the serial port with 115.2KBaud or even higher?

If not, why? Since according to the specs the ATmega is capable of communicating at these rates.

Is it as simple as writing Serial.begin(230400) ???


I use 115200 baud all the time with mine and it works fine. I don't know about higher speeds.

In theory yes...

it has been used as a DMX device which operates at that kind of speed (250000)

the rest depends on how your code is written...

you might also want to implement hardware handshaking for more reliable communication


is that what the X3 connector on the NG board is for?


you can see the connections on the schematic diagrams you find in the hardware section
