Re: [avr-gcc-list] interrupt-driven buffered UART receiver

[Harald Kipp]

Nut/OS, a tiny RTOS for the ATmega plus TCP stack, contains
a ring buffered, interrupt driven UART driver. However,
it contains also an almost full stdio implementation, which
differs from the avrlibc in that way, that it supports
fopen, fdopen, _open etc. for different devices, like the
flash file system or FAT for harddisk.

Anyway, I think that it should be possible to easily extract
the interesting UART driver parts upto fscanf. Open source
