Hello Gordon

On the EspruinoWifi. Two buttons connected:
3.3v -> A1
3.3v -> A4

Code:

pinMode(A1, "input_pulldown");
var a1=setWatch(function(e) {
    console.log('A1');
    console.log(e);
},A1, { repeat: true, edge: 'both', debounce: 200 } );

pinMode(A4, "input_pulldown");
var a1=setWatch(function(e) {
    console.log('A4');
    console.log(e);
},A4, { repeat: true, edge: 'both', debounce: 200 } );

When i push the button on A4 or A1 i also get a callback on the other watch.

Output, pressed button connected on A4:

A1
{ "state": false, "lastTime": 946685544.60812091827, "time": 946685548.80402851104 }
A4
{ "state": true, "lastTime": 946685544.78433227539, "time": 946685548.80407905578 }

I expected only receive a setWatch callback from A4.

Thanks

Corrected code. I used the same var for both setWatches.
Same output.

pinMode(A1, "input_pulldown");
var a1=setWatch(function(e) {
    console.log('A1');
    console.log(e);
},A1, { repeat: true, edge: 'both', debounce: 200 } );

pinMode(A4, "input_pulldown");
var a4=setWatch(function(e) {
    console.log('A4');
    console.log(e);
},A4, { repeat: true, edge: 'both', debounce: 200 } );

Still triggers both Watches.

That's odd - does it happen repeatedy, or just that first time?

Also, are the buttons pulling up to 3.3v, or a higher voltage? The pins should be 5v tolerant but I've noticed that if the pins are over-volted, it can actually start to cause other pins to read a voltage as well.

It happen each time. Very easy setup.

Connected the PIN 3.3v to the butten or switch and then to A1 (Btn1) and A4 (Btn2).
I think it happens on other pins too.

It triggers "false" on the other pin. This is the right value. But i do not wan't this information, because that is the current unchanged state.

There is a workaround. I will remember the states and ignore the same value.

It's strange. I just wired this up on a board here and it works great - with absolute latest and 1v95 firmware...

Ups. Hmmm. Have several EspruinoWifi's will check it again with a differnt one.
Will also reflash the 1v95.

Flashed 1V96, same result. Even on another EspruinoWifi.
I'm a bit confused.
