Detailed Description
A serial port (UART) for communication with other serial devices This is a variation of the Serial class that doesn't use streams, thus making it safe to use in interrupt handlers with the RTOS.
Can be used for Full Duplex communication, or Simplex by specifying one pin as NC (Not Connected)
Example:
// Send a char to the PC #include "mbed.h" RawSerial pc(USBTX, USBRX); int main() { pc.putc('A'); }

Constructor & Destructor Documentation
RawSerial | ( | PinName | tx, |
PinName | rx | ||
) |
Create a RawSerial port, connected to the specified transmit and receive pins.
- Parameters:
-
tx Transmit pin rx Receive pin
- Note:
- Either tx or rx may be specified as NC if unused
Definition at line 26 of file RawSerial.cpp.
Member Function Documentation
void attach | ( | T * | tptr, |
void(T::*)(void) | mptr, | ||
IrqType | type = RxIrq |
||
) | [inherited] |

- Parameters:
-
tptr pointer to the object to call the member function on mptr pointer to the member function to be called type Which serial interrupt to attach the member function to (Seriall::RxIrq for receive, TxIrq for transmit buffer empty)
Definition at line 99 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:
-
fptr A pointer to a void function, or 0 to set as none type Which serial interrupt to attach the member function to (Seriall::RxIrq for receive, TxIrq for transmit buffer empty)
Definition at line 46 of file SerialBase.cpp.
void baud | ( | int | baudrate ) | [inherited] |
Set the baud rate of the serial port.

void format | ( | int | bits = 8 , |
Parity | parity = SerialBase::None , |
||
int | stop_bits = 1 |
||
) | [inherited] |
Set the transmission format used by the serial port.
- Parameters:
-
bits The number of bits in a word (5-8; default = 8) parity The parity used (SerialBase::None, SerialBase::Odd, SerialBase::Even, SerialBase::Forced1, SerialBase::Forced0; default = SerialBase::None) stop The number of stop bits (1 or 2; default = 1)

c The char to write
- Returns:
- The written char or -1 if an error occured
Definition at line 33 of file RawSerial.cpp.
int puts | ( | const char * | str ) |
Write a string to the serial port.
- Parameters:
