• First attempt at comms to TS4231

  CNLohr • 04/22/2018 at 16:24 • 0 comments

  I was able to use the existing code I had prepared for esp8266lighthouse (https://github.com/cnlohr/esp8266lighthouse) and was able to modify the provided code from triad (https://github.com/TriadSemi/TS4231/blob/master/ts4231.cpp) to operate on the ESP8266.

  I tried configuring the TS4231 using the default configuration word 0x392B, which is the default configuration.  The TS4231 conveniently allows you to read back the configuration word so I verified it could have its configurations set arbitrarily.  Sadly, when operating the base stations at 1.8MHz, no more envelopes or data passed. So, I figured maybe the message I need to send the TS4231 a different configuration, so I chugged away...
  

  
  

  By using esp82xx's custom command system, it allows me to write javascript code to control and monitor things, so, I wrote some javascript to read GPIO inputs and configure the TS4231.  Automatically advancing through.  If the GPIOs ever received any lighting events, I would display them.  It allowed me to automatically test all 14-bit codes over the course of about 6 hours.
  

  function GPIOUpdateCallback( n, m )
  {
  	var buttons = n;
  	if( buttons != lastbuttons )
  	{
  		mark = 1;
  	}
  	lastbuttons = buttons;
  	if( countthis++ > 120 )
  	{
  		if( mark ) 
  		{
  			console.log("!!!\n");
  			document.getElementById( "results" ).innerHTML += commandid + "<BR>";
  			mark = 0;
  		}
  
                  //Set the configuration word.
  		QueueOperation( "CS"+commandid, function( req,data) { $("#custom_command_response").val( data ); } );
  
  		document.getElementById("current").innerHTML = commandid;
  		commandid++; //Advanced to next configuration word.
  		countthis = 0;
  	}
  	
  }
   
  

   I tried all 16384 combinations of config words.  There were no lighting events from the TS4231 after it was configured with the 1.8 MHz base station.  This is disheartening.  I am worried the TS4231 cannot operate at all unless there is encoded data in the OOTX and sweeps.
  
  Up Next: Will be trying to use Nairol's custom base station firmware to increase frequency of base station and see if there's any combinations that the configured TS4231 will work with.
