Pour l'instant, cela dépasse mes compétences mais dans le lien de mon précédent message il y a le fichier zip correspondant au raccourci
https://app.box.com/s/nekqcwvfc3z11imc1ksxr6htroenxjrsDans ce fichier Arduino_DCC_S88 inaccessible par le raccourci, il y a le sketch RB_DCC_Decoder_Function_ATtiny.ino ci-dessous
Est-ce que cela permet de programmer un Attiny ? Je vois que l'adresse DCC est en dur. Merci pour vos précisions.

// DCC Function Decoder
// Author: Ruud Boer - October 2015
// This sketch turns an Arduino into a DCC function decoder for F0 - F12
// Output pins used: 3-19 (14-19 = A0-A5). Pin is HIGH when Function is ON.
// The DCC signal is fed to pin 2 (=Interrupt 0).
// Optocoupler schematics for conversion of DCC - 5V:

www.mynabay.com for publishing their DCC monitor and -decoder code.
