Any data already received is discarded during the call to listen() (unless the given instance is already listening). Only one software serial port can listen at a time data that arrives for other ports will be discarded. listen Description Enables the selected software serial port to listen. Serial.println(val, format) Parameters val: The value or character string to printįormat: Specifies the number base for values (BIN: binary or base 2, OCT: octal or base 8, DEC: decimal or base 10, HEX: hexadecimal or base 16) Returns The number of bytes printed. println Description Prints a character string to the serial communications port followed by a carriage return. Serial.print(val, format) Parameters val: The value or character string to printįormat: Specifies the number base for values (BIN: binary or base 2, OCT: octal or base 8, DEC: decimal or base 10, HEX: hexadecimal or base 16) Returns The number of bytes printed. print Description Prints a character string to the serial communications port.

Len: Length of the output (written) data Returns The number of bytes of output (written) data.
ARDUINO SOFTWARE SERIAL LIBRARY SERIES
Serial.write(const unsigned char* buf, int len) Parameters str: A string to send as a series of bytes Syntax serial.flush() Parameters None Returns None write Description Writes a character string or data to the serial communications port. flush Description Waits until the send buffer of the serial communications port is empty. Syntax int serial.peek() Parameters None Returns The first byte of incoming serial data available (or -1 if no data is available). peek Description Returns the next byte (character) of incoming serial data in the serial communications port without removing it from the receive buffer. Syntax int serial.read() Parameters None Returns Data. read Description Reads 1 byte of data from the receive buffer in the the serial communications port. Syntax int serial.available() Parameters None Returns The number of bytes available in the serial buffer. Syntax serial.end() Parameters None Returns None available Description Gets the number of bytes (characters) available for reading from the serial port. Syntax serial.begin(int speed) Parameters speed: In bits per second (baud) Returns None end Description Disables serial communication port. Inverse_logic: Inverse logic (default false) Returns None begin Description Sets the data rate in bits per second (baud). SoftwareSerial(receivePin, transmitPin, inverse_logic) Parameters receivePin: Receive pin Syntax SoftwareSerial(receivePin, transmitPin) Constructor for SoftwareSerial Description This is a constructor for creating an instance of the SoftwareSerial class. You will need to create an instance of SoftwareSerial class. The receive buffer is fixed at 256 bytes. However, be careful when the baud rate is 115200bps because the reception latch timing is not so accurate. It is possible to have multiple software serial ports with speeds up to 115200bps. SoftwareSerial is a library that enables serial communication with a digital pin other than the serial port. Serial Communications (SoftwareSerial Class)
