in the meanwhile u could try ur hand at putty http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html (http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html)
it has better GUI than hyperterminal and IMO is better and easier to use than hyperterminal

Post by: rgcustodio on January 24, 2008, 12:00:15 PM: yeah i second neo01124's comment.
provide more information

also does the baud settings of the sender and receiver match? (specially if auto-baud is not being used)

Post by: JonHylands on January 24, 2008, 12:04:16 PM: Check your baud rate, check your settings (8N1), make sure you've got hardware flow control turned off, make sure you're doing TTL -> RS-232 conversion...

Post by: rox2007 on January 24, 2008, 12:06:17 PM: i am trying to relate information about my robot through uart to my computer.
I get info from the robot, but it is not readable (shown above).
i'm using uart with baud settings 38400

Post by: rox2007 on January 24, 2008, 12:24:55 PM: yes the output was the same

Post by: Admin on January 24, 2008, 01:48:05 PM: I 2nd JonHylands and rgcustodio, your baud rate is wrong somewhere.

Make sure the baud is set the same in the microcontroller software, on your PC hardware driver, and hyperterminal. Thats three different places - if you mess up one, all get messed up . . .

Post by: pomprocker on April 18, 2008, 12:29:43 PM: I've gotten this when i've done too many printf's in one control loop in my code.

Post by: paulstreats on April 18, 2008, 03:36:29 PM: yeah and without a delay between the puts or printf commands can mess up the buffer
