Furthermore, for the sky 00047 platform it's typically defined with #include "dev/uart1.h" (see 00048 rpl-boarder-router/slip-bridge.c), a sky specific file. dev/uart1.h 00049 includes msp430.h which includes the sky contiki-conf.h which 00050 defines BAUD2UBR. 00051 00052 To me, the correct think to pass is simply the baudrate and have the 00053 hardware specific conversion happen inside slip_arch_init. 00054 00055 Notably, most implementations just ignore the passed parameter 00056 anyway.
