SoftwareSerial: begin(speed)
Description
Sets the speed (baud rate) for the serial communication. Supported baud rates are 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 31250, 38400, 57600, and 115200.
Parameters
speed: the baud rate (long)
Returns
none
Example
// include the SoftwareSerial library so you can use its functions:
#include <SoftwareSerial.h>
#define rxPin 10
#define txPin 11
// set up a new serial port
SoftwareSerial mySerial = SoftwareSerial(rxPin, txPin);
void setup() {
// define pin modes for tx, rx:
pinMode(rxPin, INPUT);
pinMode(txPin, OUTPUT);
// set the data rate for the SoftwareSerial port
mySerial.begin(9600);
}
void loop() {
// ...
}
#include <SoftwareSerial.h>
#define rxPin 10
#define txPin 11
// set up a new serial port
SoftwareSerial mySerial = SoftwareSerial(rxPin, txPin);
void setup() {
// define pin modes for tx, rx:
pinMode(rxPin, INPUT);
pinMode(txPin, OUTPUT);
// set the data rate for the SoftwareSerial port
mySerial.begin(9600);
}
void loop() {
// ...
}
