Not to light up your forum Greg, but I'm sure this is a basic hardware concept I'm missing. With no WiShield, this sketch reports back an input based on a pulse. With the WiShield, it reports back nothing (and therefore doesn't post!).

No WiShield code:

Code: Select all

int inputPin = 2; // choose the input pin (for a pushbutton)
int val = 0; // variable for reading the pin status
int prevState = 0;

void setup() {
pinMode(inputPin, INPUT); // declare pushbutton as input
Serial.begin(9600);
}

void loop(){
pinMode(inputPin, INPUT);           // set pin to input
digitalWrite(inputPin, HIGH);       // turn on pullup resistors
prevState = val;
val = digitalRead(inputPin); // read input value
if (val != prevState) {
  if (val == HIGH) { // check if the input is HIGH
    Serial.print("Gallon");
    Serial.print("");
  } else {
  }
}
}



WiShield code:

Code: Select all


#include <WiShield.h>
#define WIRELESS_MODE_INFRA   1
#define WIRELESS_MODE_ADHOC   2

// Wireless configuration parameters ----------------------------------------
unsigned char local_ip[] = {192,168,10,xx};   // IP address of WiShield

Its not my forum - I just find the WiShield intriguing and have some experience writing network code. I want to see AsyncLabs succeed and this is one little thing that I can do to give them a hand.

The issue is not immediately obvious to me - it looks like it should work...

I'd start debugging this by slowly removing/commenting networking code until something becomes apparent. So a few questions I would seek to answer are:

• Does the original, working, example still work if you switch it to pin 5 as well?
• Do the first two lines of your loop() function really need to be there (I'm sure this is not related but I'm wondering if they even need to be there)
• What happens if you swap the order of webclient_get() and Serial.print() (or just comment out webclient_get()) - do you get the serial output of "Gallon" then?

Just basic troubleshooting steps done one at a time, then tested, to see where things are going off of the hook.

Edit - this is interesting to me as a learning experience so I'm going to try to look at it on real hardware. Was going to look at it last night but got interested in the multiple UDP port issue thread (and it did not require connecting a switch/wires)

Ha, I got a kick outta that. Greg, you do so much work around here, people are starting to think you own the place

I see you're using digital pin 2 as the push button. Are you then using dig8 as the WiShield interrupt pin? ( set in spi.h )

Greg is right, you don't need pinMode() in the loop, unless you're switching it to OUTPUT somewhere else.

Didn't you hear? I'm the new owner and you owe me $0.25 for your last post

Frank is using pin 2 in his non WiShield code and pin 5 in his WiShield code - one of my questions was about the proper operation of pin 5 in the non WiShield code.

TGIF!!!
