@mtz: just call Serial.begin(1000000L);
This version uses exactly the same functions as the original one. It's transparent for the programmer.
@halley: I'm not sure how the makefile is written, but in my case, whenever I change the wiring_serial.c file it is automatically recompiled. It'd be awesome if one could put the
#define RX_BUFFER_SIZE yourvalue
at the beginning of the sketch file so there's no need to edit the library. With a smart code in the library:
#ifndef RX_BUFFER_SIZE
#define RX_BUFFER_SIZE 128
#endif
