the tinkerbell files!

Here are the schematics and the code for tinkerbell the wirless dmx fairy.

#include <lib_dmx.h>  // comment/uncomment #define USE_UARTx in lib_dmx.h as needed

// This example receive 4 channels from address 1 to 4 and write analog values to PWM pins 2 to 5

// outputs update in main loop

#define    DMX1024    (1)    // (500 kbaud - 2 to 1024 channels) Completely non standard - TESTED ok

void setup()

  ArduinoDmx0.set_rx_address(1);      // change starting adress here

  digitalWrite(5,LOW);

  delay (300);  

    digitalWrite(5, HIGH);

  delay (300);

  digitalWrite(5,LOW);

  // 2 blinks for on

  

}  //end setup()

void loop()

{

  //write values from dmx channels 1-4 universe 0 to arduino pwm pins 2-5

  analogWrite(5, ArduinoDmx0.RxBuffer[0]);  //buffers 0 indexed

}  //end loop()

as you can see you will need a dmx library from deskontrol.net . this is almost their programing example with minor changes. the output Onoff i just a  indicator that the Arduino has power and is ready to recive dmx.

i will publish the pcb files. but they are not ready yet.
