OSHChip 0:69ded1c7cad0 9 // By the time your program gets to main(), the pre-main initialization has
OSHChip 0:69ded1c7cad0 10 // (among other things) setup the UART to use the nRF51-DK UART pins, and a

OSHChip 0:69ded1c7cad0 19 // For OSHChip, the default is TX on pin 1, RX on pin 2, and no CTS or RTS
OSHChip 0:69ded1c7cad0 20 // because OSHChip has so few I/O pins.
OSHChip 0:69ded1c7cad0 21 //
OSHChip 0:69ded1c7cad0 22 // Due to the default implementation of Serial I/O in mbed, when \n
OSHChip 0:69ded1c7cad0 23 // is set to the UART, all that is actually transmitted is the "newline".
OSHChip 0:69ded1c7cad0 24 // In a Unix/Mac environment this is usually sufficient, but in a
OSHChip 0:69ded1c7cad0 25 // DOS/Windows environment, \n\r needs to be sent.
