Hi all,
I'm try to use a virtual wire with arduino shield:
virtual wire :
tx pin: 12
rx pin: 11
When I compile the sketches I received this issues:
Servo/Servo.cpp.o: In function __vector_11': /Applications/Arduino.app/Contents/Resources/Java/libraries/Servo/Servo.cpp:103: multiple definition of __vector_11'
VirtualWire/VirtualWire.cpp.o:/Applications/Arduino.app/Contents/Resources/Java/libraries/VirtualWire/VirtualWire.cpp:416: first defined here
My understanding is that there is a issues with the pin 11 I've tried to check "servo.cpp" and "VirtualWire.cpp" but I didn't found nothing,
The Ethernet shield is an SPI device. It uses pins 11, 12, and 13 for SPI purposes. It uses pins 4 and 10 as slave select pins. None of those pins is available for your application to use.
from your stand point is there the possibility to modify the tx and rx of Virtualwire library ?
The VirtualWire library has two methods, vw_set_tx_pin and vw_set_rx_pin, that allow you to use any pins you want. The defaults are 12 and 11, but you can change them by calling these functions. You also need to call vw_set_ptt_pin to get off pin 10.
Hi again,
I've tried to modify the code followint your suggestion maybe im wrong something ? following the code ... I've called the function after vw_setup ...
#include <VirtualWire.h>
#include <SPI.h>
#include <Ethernet.h>
#include <Servo.h>
Servo myservo; // create servo object to control a servo
byte mac[] = { 0x90, 0xA2, 0xDA, 0x00, 0x8D, 0x64 }; //physical mac address
byte ip[] = { 192, 168, 1, 102 }; // ip in lan
byte gateway[] = { 192, 168, 1, 1 }; // internet access via router
byte subnet[] = { 255, 255, 255, 0 }; //subnet mask
EthernetServer server(84); //server port
String readString;
//////////////////////
void setup(){
Serial.begin(9600);
vw_setup(1200);
vw_set_tx_pin(2);
vw_set_rx_pin(3);
vw_set_ptt_pin(5);
pinMode(8, OUTPUT); //pin selected to control
//start Ethernet
Ethernet.begin(mac, ip, gateway, subnet);
server.begin();
myservo.write(90); //set initial servo position if desired
myservo.attach(7); //the pin for the servo co
//enable serial data print
Serial.println("server LED test 1.0"); // so I can keep track of what is loaded
}
void loop(){
// Create a client connection
EthernetClient client = server.available();
if (client) {
while (client.connected()) {
if (client.available()) {
char c = client.read();
//read char by char HTTP request
if (readString.length() < 100) {
//store characters to string
readString += c;
//Serial.print(c);
}
//if HTTP request has ended
if (c == '\n') {
///////////////
Serial.println(readString); //print to serial monitor for debuging
client.println("HTTP/1.1 200 OK"); //send new page
client.println("Content-Type: text/html");
client.println();
client.println("<HTML>");
client.println("<HEAD>");
client.println("<TITLE>Arduino GET test page</TITLE>");
client.println("</HEAD>");
client.println("<BODY>");
client.println("<H1>Test Button</H1>");
client.println("<a href=\"/?on\"\">ON</a>");
client.println("<a href=\"/?off\"\">OFF</a>");
client.println("</BODY>");
client.println("</HTML>");
delay(1);
//stopping client
client.stop();
///////////////////// control arduino pin
if(readString.indexOf("on") >0)//checks for on
{
myservo.write(40);
char msg[1];
msg[0] = '1';
vw_send((uint8_t *)msg, strlen(msg)); // invia la lettera a
Serial.println("Led On");
}
if(readString.indexOf("off") >0)//checks for off
{
myservo.write(140);
digitalWrite(8, LOW); // set pin 8 low
Serial.println("Led Off");
}
//clearing string for next read
readString="";
}
}
}
}
}
The exact error is this:
Servo/Servo.cpp.o: In function __vector_11': /Applications/Arduino.app/Contents/Resources/Java/libraries/Servo/Servo.cpp:103: multiple definition of __vector_11'
VirtualWire/VirtualWire.cpp.o:/Applications/Arduino.app/Contents/Resources/Java/libraries/VirtualWire/VirtualWire.cpp:416: first defined here
Hi All,
the problem is that ... looking Servo.cpp: (line 103) and VirtualWire.cpp (line 416) that function SIGNAL (TIMER1_COMPA_vect) is present in both ...
Then I've change the function in VirtualWire.cpp putting SIGNAL (TIMER6_COMPA_vect) because the other one arrive until 5 ... in compile mode there is no problem ... but I've note that the serial monitor is not working anymore ...due the fact putting back like initial the serial monitor can works ...
How I can do to remove the issues and continue to work ?? SIGNAL (TIMER1_COMPA_vect) maybe is call in other parte that I didn't know ... I can try to modify to the servo.cpp part ?
