WiFi Shield V2.2 stack with arduino leonardo
priangga 2013-01-12 22:41:01 5325 Views3 Replies Hi all , i've bought Wifi Shield V2.2 and going to make project with this stuff, i use arduino leonardo for the controller. i have a problem to configure wiznet modul, i have set the shield to USB mode by switch it, but i cant connect the AT mode on my serial terminal , i have try the tutorial but it doesnt work, can anybody help me :(
2013-04-05 22:24:35 Thx Lauren for your attention, i've tried to upload that code to leonardo before stack my wifi shield into it, then i switched to usb mode, and set my serial terminal in this case i used putty, but when i tried the at command there's no respond, and the assoc and stw indicator still down, as i know that when i type "at" (without string) i suppose to get the reply [OK] in the terminal but im not, could you help me please, sorry for my bad english , regard priangga
priangga 2013-04-04 12:52:18 Hey,
I was reading about the same issue and came up with your solution. It works! The only thing is that I needed to set the USB/Arduino switch on the DFRobot wifi shield V2.2 to "Arduino."

**, the reason is the Leonardo have two serial interface. However the Arduino Uno just one serial port which is shared using by USB and D0,D1. So you need to upload a simple code to create the communication between USB port to D0 and D1 on the Arduino Leonardo. Here's a sample code got from google.
I checked it. I think it should work for you. Please try it!
[code]/*
leo_usb2serial
Allows to use an Arduino Leonardo as an usb to serial converter.
*/
static long baud = 115200;
static long newBaud = baud;
// this pin will output the DTR signal (as set by the pc)
#define DTR_PIN 13
#define LINESTATE_DTR 1
void lineCodingEvent(long baud, byte databits, byte parity, byte charFormat)
{
newBaud = baud;
}
void lineStateEvent(unsigned char linestate)
{
if(linestate & LINESTATE_DTR)
digitalWrite(DTR_PIN, HIGH);
else
digitalWrite(DTR_PIN, LOW);
}
void setup() {
pinMode(DTR_PIN, OUTPUT);
digitalWrite(DTR_PIN, LOW);
Serial.begin(baud);
Serial1.begin(baud);
}
void loop() {
// Set the new baud rate
// if(newBaud != baud) {
// baud = newBaud;
// Serial1.end();
// Serial1.begin(baud);
// }
// copy from virtual serial line to uart and vice versa
if (Serial.available()) {
char c = (char)Serial.read();
Serial1.write(c);
}
if (Serial1.available()) {
char c = (char)Serial1.read();
Serial.write(c);
}
}[/code]
Look forward to your testing result! ;)
