Title: Does anyone know how to do UART for Atmega32 with Avrlib
Post by: rox2007 on April 19, 2008, 01:47:55 PM

I just changed my chip from atmega168 to Atmega32, but when i try to read info in hyperterminal all i get is gibberish. I have tried everything i know.
Thank you

you probably have the wrong baud speed.

wrong baud speed or your capacitors in your max232 are not well connected

Just follow these instructions on how to use AVRlib for uart:

(and yea, the gibberish means your baud rates are mis-matched)
