Detailed Description

SoftwareSerial controller.

You can control Software Serial comunication by operating SoftwareSerial objects instantiated in your app. It is usable on all the GPIO pins (D0 - D28).

Constructor & Destructor Documentation

SoftwareSerial()

SoftwareSerial::SoftwareSerial	(	uint8_t	receivePin,
		uint8_t	transmitPin )

Create SoftwareSerial object.

Parameters

[in]	receivePin	Pin used for receive
[in]	transmitPin	Pin used for transmit

Member Function Documentation

begin()

void SoftwareSerial::begin

(

long

speed

)

Initialize the serial communication.

Parameters

[in]

speed

Baud rate. The maximum speed is 250,000 bps.

listen()

bool SoftwareSerial::listen

(

)

Sets the current object as the "listening" one.

Returns

true if success, false if failure

isListening()

bool SoftwareSerial::isListening ( )

inline

Checks if the SoftwareSerial object is listening.

Returns

true if is listening

stopListening()

bool SoftwareSerial::stopListening

(

)

Stop listening.

Returns

true if we were actually listening

overflow()

bool SoftwareSerial::overflow ( )

inline

Checks if a SoftwareSerial buffer overflow has occurred.

Returns

true if overflow

peek()

int SoftwareSerial::peek

(

)

Get a character that was received on the RX pin of the SoftwareSerial object.

Subsequent calls to this function will return the same character.

Returns

the character read, or -1 if none is available

write()

virtual size_t SoftwareSerial::write ( uint8_t byte )

virtual

Send a single byte to the transmit pin of SoftwareSerial object.

Parameters

[in]

byte

Byte to write

Returns

Return the number of bytes written

read()

virtual int SoftwareSerial::read ( )

virtual

Read data from buffer.

Returns

The byte read, or -1 if none is available

available()

virtual int SoftwareSerial::available ( )

virtual

Get the number of bytes available for reading from a SoftwareSerial objects.

Returns

number of bytes available to read

handle_interrupt()

static int SoftwareSerial::handle_interrupt ( int irq, FAR void * context, FAR void * arg )

inlinestatic

Interrupt handling.

Parameters

[in]	irq	Interrupt number
[in]	context	Context (not used)
[in]	arg	Argument (not used)
