zer044 0:a4b73f736e46 6 Before to use this example, ensure that you an hyperterminal installed on your
zer044 0:a4b73f736e46 7 computer. More info here: https://developer.mbed.org/handbook/Terminals
zer044 0:a4b73f736e46 8
zer044 0:a4b73f736e46 9 The default serial comm port uses the SERIAL_TX and SERIAL_RX pins (see their
zer044 0:a4b73f736e46 10 definition in the PinNames.h file).
zer044 0:a4b73f736e46 11
zer044 0:a4b73f736e46 12 The default serial configuration in this case is 9600 bauds, 8-bit data, no parity
zer044 0:a4b73f736e46 13
zer044 0:a4b73f736e46 14 If you want to change the baudrate for example, you have to redeclare the
zer044 0:a4b73f736e46 15 serial object in your code:
zer044 0:a4b73f736e46 16
zer044 0:a4b73f736e46 17 Serial pc(SERIAL_TX, SERIAL_RX);
zer044 0:a4b73f736e46 18
zer044 0:a4b73f736e46 19 Then, you can modify the baudrate and print like this:
zer044 0:a4b73f736e46 20
zer044 0:a4b73f736e46 21 pc.baud(115200);
zer044 0:a4b73f736e46 22 pc.printf("Hello World !\n");
