<p class='vspace'></p><h2><span class='wikiword'>SoftwareSerial</span>: begin(speed)</h2>
|
|
<h4>Description</h4>
|
|
<p>Sets the speed (baud rate) for the serial communication. Using speeds higher than 9600 baud will result in faulty communication.
|
|
</p>
|
|
<p class='vspace'></p><h4>Parameters</h4>
|
|
<p>speed: the baud rate (<em>long</em>)
|
|
</p>
|
|
<p class='vspace'></p><h4>Returns</h4>
|
|
<p>none
|
|
</p>
|
|
<p class='vspace'></p><h4>Example</h4>
|
|
<pre>// include the SoftwareSerial library so you can use its functions:
|
|
#include <SoftwareSerial.h>
|
|
|
|
#define rxPin 2
|
|
#define txPin 3
|
|
|
|
// 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() {
|
|
// ...
|
|
}
|
|
|
|
</pre>
