- Wed Apr 22, 2015 5:16 am #15270 Is anyone able to help with an example of AJAX/JSON creating a dynamic table from an array in the webserver?

I've created the response sending the JSON array but I'm struggling with the jQuery/html bit.

I didn't have any problems with using interrupt in Sming. I think I am using 1.0.5.
Will this simple code work for you? ( Paste into Basic_Serial e.g.)

Code: Select all#include <user_config.h>
#include <SmingCore/SmingCore.h>

#define INT_PIN 0   // GPIO0

void interruptHandler()
{
   Serial.println("Pin changed");
}

void init()
{
   Serial.begin(SERIAL_BAUD_RATE); // 115200 or 9600 by default
   attachInterrupt( INT_PIN, interruptHandler, CHANGE);
}

But how is the best way to import the new sming with mqtt into Eclipse workspace that already has the existing Sming?

Just download latest actual source code. Also you can automatically update it via GIT.

If you problem in Sming code I'm ready to answer. If it's a jQuery related, you can find many jQuery manuals and examples on stackoverflow and specialized sites. It's absolutely equal in Sming environment.

Thank you for provided example. I have merged it into repo, but much better in real application don't execute additional code in interrupt handler (just get state, set flag and etc.)

Hi anakod

I've managed to get the jQuery working using a hard coded array.
I'm now having a problem taking this example further using a list that is returned from the Wifi scanning. It may be my lack of understanding of C/C++ but any help is appreciated.

In the listNetworks method I've copied the BssList to a global variable using memcpy but when I try and use the global variable in the onAjax.... method to create the JSON response the module restarts. I assume it's some sort of memory error causing a crash.

Any ideas what I'm doing wrong?
