shiva_shankar 0:9ba1d65b12c1 4 Before to use this example, ensure that you an hyperterminal installed on your
shiva_shankar 0:9ba1d65b12c1 5 computer. More info here: https://developer.mbed.org/handbook/Terminals

shiva_shankar 0:9ba1d65b12c1 7 The default serial comm port uses the SERIAL_TX and SERIAL_RX pins (see their
shiva_shankar 0:9ba1d65b12c1 8 definition in the PinNames.h file).
shiva_shankar 0:9ba1d65b12c1 9
shiva_shankar 0:9ba1d65b12c1 10 The default serial configuration in this case is 9600 bauds, 8-bit data, no parity
shiva_shankar 0:9ba1d65b12c1 11
shiva_shankar 0:9ba1d65b12c1 12 If you want to change the baudrate for example, you have to redeclare the
shiva_shankar 0:9ba1d65b12c1 13 serial object in your code:
shiva_shankar 0:9ba1d65b12c1 14
shiva_shankar 0:9ba1d65b12c1 15 Serial pc(SERIAL_TX, SERIAL_RX);
shiva_shankar 0:9ba1d65b12c1 16
shiva_shankar 0:9ba1d65b12c1 17 Then, you can modify the baudrate and print like this:
shiva_shankar 0:9ba1d65b12c1 18
shiva_shankar 0:9ba1d65b12c1 19 pc.baud(115200);
shiva_shankar 0:9ba1d65b12c1 20 pc.printf("Hello World !\n");
