 *  Use at your own Risk! 
 *  
 *  *  This example at https://github.com/hpssjellis/my-examples-for-the-arduino-portentaH7/blob/master/my15-TRACE32.ino
 *  
 *  My resources and links about Assembly languages at https://github.com/hpssjellis/my-examples-for-the-arduino-portentaH7/tree/master/ASM
 *  
 *  1. Download TRACE32 from https://www.lauterbach.com/frames.html?download_demo.html 
 *  Scroll down the long page until you see Arduino Pro 
 *  Download and unzip then create a shortcut of the bin--> windows64-->t32marm.exe file to your desktop. 
 *  If you use Ubuntu Linux pre download qt5 with this command
 *  sudo apt-get install qt5-default
 *  as always with Linux expect port permissions issues.
 *  
 * 2. Pro Arduino Tutorial https://www.arduino.cc/pro/tutorials/portenta-h7/por-ard-trace32
 * 
 * 3. Get Your Portenta SN from the Arduino IDE, Tools-->Board Info (plug in Portenta a select port )
 * 
 * 4. license either now or later at https://www.lauterbach.com/frames.html?register_arduino.php
 * 
 * 5. Read your replied email for a license code. Put the long line of code in a file called license.t32
 *    Add a new line for each Portenta you own.
 *    Copy the license.t32 file into the main folder of Trac32
 * 
 * 5. Put the following Thread debug lines in your code, compile and flash as usual
 * 
 * 6. Load Trace32 and click on "Portenta H7 Projects -->Slect Your Arduino Project Directory"
 * 
 * 7. Click on "Arduino Classic IDE"--> must double click the temp file --> click OK
 * 
 * 8. go loop
 * 
 * 9. set a breakpoint if needed
 *
