Доброго времени суток.!
Есть ATMega32. В CodeVisionAVR (1.25.9 Pro) USART сконфигурирован. В хелпе сказано что с ним надо работать стандартными средствами putchar, getchar, и т.д. Посылаю байт в него, ничего не происходит. Что я делаю не так. Подскажите, пожалуйста, как работать
P.S. самое проблемное! помогите его подключить, пожалуйста!

#include <mega32.h>

С Code Wizard'ом обычно проблем нет.
А как вы подключаете к COM порту? И работает ли переходник UART<>COM/USB через который вы подключаете?
