Hi,

I'm workin on a project.
I need to scan 8 external buttons.
Therefore I use the setWatch function.
But it looks like the Espruino can't handle 8 setWatch functions.
If I disable (make a comment of it) a few setWatch, then it is working fine for these buttons.

The pins I used are C7, C8, C9, C10, C11, A8, A9 ad A10
Tis is the setWatch line
```
  setWatch(visitorScoreUp, A9, {repeat: true, edge: 'falling', debounce: 300});
```
The other pin of the button is connected to the GND

Regards
Peter

That is a limitation of the microcontroller:

You can't setWatch on two pins with the same number (eg. A5 and C5) - this is a limitation of the STM32F1

From the Known problems section in the Original Espruino Board's docs.
