LSM9DS1 A 9 degree of freedom Inertial Navigation Chip

At this point the module slimLSM9DS1.js needs to be tested.
In order to do the testing the menutestSlimLSM9DS1.js has been written, with another program to test the calibration module to follow.
WARNING WARNING WARNING
The menu system redirects the USB port away from the console. Without a method to restore the USB-Console connection or reset a Pico you can brick the Pico if you save the menu program. As written the menu program provides three exits. Control-C, Menu option 9, and the pushbutton on the Pico. When you load the program it tells you to type startPGM(); in the left pane of the WebIDE. This is safe. Only save the program once you are convinced that all the exit methods work. This is especially true if you make modifications to the menu program.
Here is an example after the menu program is loaded, started and menu option 9 is selected.

>In left pane type startPgm();
Use startPgm() first and make sure you can exit back to the console
Once you are sure that a proper exit works then type  save();
=undefined
>startPgm();

The code to use the pushbutton to reset the Pico is in nobrick.js
It does not redirect the USB port.

//How not to brick a PICO when reassigning the console
// away from the USB port to do menu programs

//Setup the button to light the LED and reset the Pico
//Always include this code when a save() and oninit() functions are // used.
setWatch(function(e) {
  digitalWrite(LED1, e.state);
  USB.setConsole();
  reset();
}, BTN, { repeat: true });

E.on('init', function() {
 console.log("Hello");
 startPgm();
});

function startPgm(){
var count=0;
var nn=setInterval(function () {
    console.log(count);
    count++;
    if(count>1000)clearInterval(nn);
}, 200);
}//end startPgm
console.log("In left pane type startPgm();");
console.log("Use startPgm() first and make sure you can exit back to the console");
console.log("Once you are sure that a proper exit works then type  save();");
