PiDuino Library

Serial.begin(driverName, speed, config)

Opens a serial port with at specified serial device driver name and with the specified speed (baud rate) and serial port config options.

Parameters

driverName - Serial port driver Name (e.g “/dev/ttyAMA0”)

speed - Serial port baud rate. (See Notes)

config - Serial port configuration options like Data Size, Parity and StopBits. (See Notes)

Returns

None

Example

#include <Arduino.h>

void setup() {
	// Open Serial port with:
	// Device driver name = "/dev/ttyAMA0"
	// baud rate: 9600
	// Data size: 8 bits
	// Parity: None
	// Stop Bits: 1 bit
	Serial.begin("/dev/ttyAMA0", 9600, SERIAL_8N1);
}

void loop() {
	Serial.println("Hello World");
	delay(1000);
}

Notes

• Available speeds (baud rates). Default is 9600

• Available serial port configurations. Default is SERIAL_8N1

• Serial default device driver is “/dev/ttyAMA0”. if you want to change the default device driver change the SERIAL_DRIVER_NAME constant as the example below.

#include <Arduino.h>

void setup() {
        strcpy(SERIAL_DRIVER_NAME, "/dev/ttyAMA1");
        Serial.begin(9600);
}

void loop() {
        Serial.println("Hello World");
        delay(1000);
}
