[SOLVED] Updated and Accurate Serial Specifications

Hi, I can't seem to find anything accurate for all of the Arduino models on the following specs:

  • Parity
  • Start Bits
  • Stop Bits
  • Data Bits
  • Flow Control

I need the specs for both the USB and hard-wired serial. Are there any differences between the Mega, Uno, and other boards?

Thanks!

AFAIK all Arduinos have 8N1 format and no flow control. You can change it yourself by dicking with the UART's control registers but the Arduibo core libs are 8N1.

I see. Thanks! I'm still amazed at how fast this forum produces answers.

According to Wikipedia:

8-N-1 is a common shorthand notation for a serial port parameter setting or configuration in asynchronous mode, in which there are eight (8) data bits, no (N) parity bit, and one (1) stop bit.[1] As such, 8-N-1 is the most common configuration for PC serial communications today.

This is the first time I have had to disable smilies! 8) = the cool sunglasses dude.
