baud rate autodetection on AVR 8-bit? 70 35 (12/7/2012 2:17:16 PM) comp.arch.embedded BTW, is there an easy way to autodetect the baud rate while using an AVR UART? (Preferably something that works with ATmega8, given that those MCU's are such a cheap thing nowadays.) There're some i... Ivan

"\x1337\xcafe"? 15 40 (11/19/2012 6:55:21 AM) comp.lang.c Somehow, I assumed that the following two definitions are equivalent: unsigned char buf[] = ("\x1337\xcafe"); unsigned char buf[] = ("\x13" "37\xca" "\xfe"); However, it turns out... Ivan

A C++-Language Question (Maybe C, too) 64 17 (4/2/2013 12:01:32 AM) comp.arch.embedded Technically this should be on the C++ language group, but I want an answer, not to either be sneered at or to start a religious war.
