Bonjour,
Mon projet est de pouvoir commander des éclairages DMX12 depuis ma box Domotique.
La box dispose des protocoles suivant : Z-wave, Zigbee, DIO Chacon, Somfy RTS, ...
Réalisation en cours :
- une carte Arduino Nana
- un récepteur RF433
- une carte MAX485
Avec le programme suivant je reçois bien les commandes RF433 DIO Chacon envoyées par la box Domotique.

This example captures codes sent by DiO 433MHz remotes. To read
the frames, plug a RX 433MHz module to the Arduino, to pin 2.
Open serial monitor at 9600 bauds. Aim the remote at the module,
and the code will be display in the monitor. Capture "On" and "Off"
codes.

// Identify current bit based on the pulse length
if (t > DiOremote_0_TLOW && t < DiOremote_0_THIGH)
currentBit = 0;

currentBit = 1;
else
break;
// If bit count is even, check Manchester validity & store in code
if (i % 2) {
// Code validity verification (Manchester complience)
if (!(previousBit ^ currentBit))
break;
// Store new bit
code <<= 1;
code |= previousBit;
}
previousBit = currentBit;
}
}
// Send the code via serial
if (i == DiOremote_FRAME_LENGTH)
Serial.println(code);
}
Quand je charge le programme suivant je commande bien l'éclairage DMX512 depuis le Moniteur Série.
/*DMX
*/
#include <DmxSimple.h>
// -- Setup ---
void setup() {
Serial.begin(9600);
Serial.println("SerialToDmx ready");
Serial.println();
Serial.println("Syntax:");
Serial.println(" 123c : use DMX channel 123");
Serial.println(" 45w : set current channel to value 45");
// Enable DMX master interface and start transmitting
DmxSimple.usePin(3);
}
// -- Initalisation --
int channel;
int value = 0;
// -- Loop --
void loop() {
int c;
while(!Serial.available());
c = Serial.read();
if ((c>='0') && (c<='9')) {
value = 10*value + c - '0';
} else {
if (c=='c') channel = value;
else if (c=='w') {
DmxSimple.write(channel, value);
Serial.println(channel);
Serial.println(value);
Serial.println();
}
value = 0;
}
}
Mon souci est quand je charge la compilation de ces deux programmes, je peux toujours commander l'éclairage depuis le Moniteur Série, mais je ne reçois plus les commandes RF433 DIO Chacon.

Même résultat avec une car UNO.
