In Switzerland we call it Vermicelles, it’s made out of cooked and pureed chestnuts, served with whipped cream and meringues (no idea how to translate this, it’s baked egg-whites with sugar). It’s a typical autumn dessert.

Looking it up it’s seemingly known as Mont Blanc abroad, though i’ve never heard it called that here.

Interesting read. I wonder where OP got the specs for the device itself, i.E. what it expects in terms of data and what the response (interrupt) values mean?
