 Serial (PinName tx, PinName rx, const char *name=NULL, int baud=MBED_CONF_PLATFORM_DEFAULT_SERIAL_BAUD_RATE)
 Create a Serial port, connected to the specified transmit and receive pins.
 Serial (PinName tx, PinName rx, int baud)
 Create a Serial port, connected to the specified transmit and receive pins, with the specified baud.
void baud (int baudrate)
 Set the baud rate of the serial port.
void format (int bits=8, Parity parity=SerialBase::None, int stop_bits=1)

Detailed Description

A serial port (UART) for communication with other serial devices.

Can be used for Full Duplex communication, or Simplex by specifying one pin as NC (Not Connected)

Synchronization level: Thread safe

Example: 

 // Print "Hello World" to the PC

 #include "mbed.h"

 Serial pc(USBTX, USBRX);

 int main() {
     pc.printf("Hello World\n");
 }

Member Function Documentation

void baud ( int  baudrate ) [inherited]

Set the baud rate of the serial port.

Parameters:
baudrateThe baudrate of the serial port (default = 9600).

Definition at line 43 of file SerialBase.cpp.

MBED_DEPRECATED_SINCE ( "mbed-os-5.4"  ,
"Replaced by FileLike::seek"   
) [inherited]

Move the file position to a given offset from a given location.

Parameters:
offsetThe offset from whence to move to
whenceSEEK_SET for the start of the file, SEEK_CUR for the current file position, or SEEK_END for the end of the file.
Returns:
new file position on success, -1 on failure or unsupported
