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)

Example: 

 // Print "Hello World" to the PC

 #include "mbed.h"

 Serial pc(USBTX, USBRX);

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

Constructor & Destructor Documentation

Serial ( PinName  tx,
PinName  rx,
const char *  name = NULL 
)

Create a Serial port, connected to the specified transmit and receive pins.

Parameters:
txTransmit pin
rxReceive pin
Note:
Either tx or rx may be specified as NC if unused

Member Function Documentation

void attach ( T *  tptr,
void(T::*)(void)  mptr,
IrqType  type = RxIrq 
) [inherited]

Attach a member function to call whenever a serial interrupt is generated.

Parameters:
tptrpointer to the object to call the member function on
mptrpointer to the member function to be called
typeWhich serial interrupt to attach the member function to (Seriall::RxIrq for receive, TxIrq for transmit buffer empty)

Definition at line 92 of file SerialBase.h.

void attach ( void(*)(void)  fptr,
IrqType  type = RxIrq 
) [inherited]

Attach a function to call whenever a serial interrupt is generated.

Parameters:
fptrA pointer to a void function, or 0 to set as none
typeWhich serial interrupt to attach the member function to (Seriall::RxIrq for receive, TxIrq for transmit buffer empty)
void baud ( int  baudrate ) [inherited]

Set the baud rate of the serial port.

Parameters:
baudrateThe baudrate of the serial port (default = 9600).
void format ( int  bits = 8,
Parity  parity = SerialBase::None,
int  stop_bits = 1 
) [inherited]

Set the transmission format used by the serial port.

Parameters:
bitsThe number of bits in a word (5-8; default = 8)
parityThe parity used (SerialBase::None, SerialBase::Odd, SerialBase::Even, SerialBase::Forced1, SerialBase::Forced0; default = SerialBase::None)
stopThe number of stop bits (1 or 2; default = 1)
int readable (  ) [inherited]

Determine if there is a character available to read.

Returns:
1 if there is a character available to read, 0 otherwise
void send_break (  ) [inherited]

Generate a break condition on the serial line.

int writeable (  ) [inherited]

Determine if there is space available to write a character.

Returns:
1 if there is space to write a character, 0 otherwise
