Bibliothèque NmraDcc-simple DCC Multifunction (Locomotive) decoder

[Benoit92]

Bonjour,
Pour ceux que cela peut intéresser, un"simple DCC Multifunction (Locomotive) decoder" a été ajouté (il y a un mois) sur Github :
https://github.com/mrrwa/NmraDcc
https://github.com/mrrwa/NmraDcc/blob/master/examples/NmraDccMultiFunctionMotorDecoder/NmraDccMultiFunctionMotorDecoder.ino

Il permet le pilotage de la traction, des feux et de l'éclairage.
Pour le son, c'est une autre paire de manche !

Ce logiciel peut être installé sur :
 - Arduino UNO
 - ATTiny85

Il faut ajouter :
- Un adaptateur de signal DCC (optocoupleur) rails -> Arduino,
- Un pont en H (Arduino -> Moteur CC),
- Un 7805 -> 5V pour le VCC de l'optocoupleur,
- Un pont de diode + gros condensateur pour la puissance du pont en H,
- Des Leds pour les feux et l'éclairage (en utilisant des leds bicolore jaune/rouge, on peut simplifier le câblage)
En utilisant un ATTiny85, je pense que ce décodeur peut être intégré sur des locomotives au minimum à l'échelle O.
Je doute cependant que ce décodeur puisse être installé sur des locomotives à l'échelle HO ou peut-être sur des vapeurs avec tender.

Bonjour @ tous,

Merci Benoit92

Bonjour, en attendant de recevoir mon ATtiny85, j'ai essayé de "vérifier/compiler" le programme "simple DCC Multifunction (Locomotive) decoder" :

// NMRA Dcc Multifunction Motor Decoder Demo

// Author: Alex Shepherd 2019-03-30
//
// This example requires these Arduino Libraries:
//
// 1) The NmraDcc Library from: http://mrrwa.org/download/
//
// These libraries can be found and installed via the Arduino IDE Library Manager
//
// This is a simple demo of how to drive and motor speed and direction using PWM and a motor H-Bridge
// It uses vStart and vHigh CV values to customise the PWM values to the motor response
// It also uses the Headling Function to drive 2 LEDs for Directional Headlights
// Apart from that there's nothing fancy like Lighting Effects or a function matrix or Speed Tables - its just the basics...
