Stellaris as a tool

[Desmond 0]

The best example of Stellaris as a tool is as a logic analyzer see here.. http://www.sodnpoo.com/posts.xml/variable_sample_rate_stellaris_logic_analyser.xml

 

Currently I am working with the ESP8266 modules and I wanted to see what was being transmitted and received over  the serial interface without cluttering my code with debug.

 

Stellaris is perfect.

  debugSerial.begin(115200);
  debugSerial.println("Stellaris Serial MUX starting.....");

  // set the data rate for the monitored ports
  Serial1.begin(9600);
  Serial2.begin(9600);
  Serial3.begin(9600);

}

void loop() // run over and over
{
  while (Serial1.available()){
    debugSerial.write("\x1b[37;1m");
    debugSerial.write(Serial1.read());   
  }

  }  
 
   while (debugSerial.available())  Serial1.write(debugSerial.read());

Pretty cool!

I want to do something similar but I didn't understand what values to send to the logic analyzer software!
