cleanup uart stuff - use new per-cpu headers - remove interrupt handling from uart functions - correct baudrate calculation - introduce UART_DOUBLESPEED to use fast mode - introduce UART_SECOND to use 2nd uart on mega128 - move uart functions to main.c, delete uart.[ch] - rename XTAL to F_CPU (avrlibc style) - move some defines from Makefile to main.c 2006-05-19 22:19:18 +02:00
