Yes - I use this for all of my UART stuff. You can find interrupt based UART code which uses CBUF over here: <http://websvn.hylands.org/filedetails.php?repname=Projects&path=%2Fcommon%2Favr%2FUART.h&rev=0&sc=0> <http://websvn.hylands.org/filedetails.php?repname=Projects&path=%2Fcommon%2Favr%2FUART.c&rev=0&sc=0> A typical Config.h (which can be different for each project) looks like this: <http://websvn.hylands.org/filedetails.php?repname=Projects&path=%2Favr%2FFlash-LED-robostix%2FConfig.h&rev=0&sc=0> -- Dave Hylands Shuswap, BC, Canada http://www.DaveHylands.com/ _______________________________________________ AVR-GCC-list mailing list AVR-GCC-list@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
