So here's a recap of what i've managed to achieve so far and what problems I'm experiencing.

I am running an XBMCBuntu on an Intel Pentium 4 device. For the time beign I'm keeping things extra simple to eliminate possible points of failure. My circuit consists of an Arduino Uno connected to the PC's USB port. A single RGB LED is connected to the arduino with the GND connected to the GND pin on the Arduino and the remaining 3 pins connected to PWM outputs 9,10 and 11.

Running $ boblightd& on xbmc gives me the following output:

Code:

james@XBMC-Eden:~$ boblightd&

james@XBMC-Eden:~$ (InitLog)                       start of log /home/james/.bob                                                                             light/boblightd.log

(CClientsHandler::ParseSet)     127.0.0.1:42906 priority set to 128
^C

At this point the Rx indicator on the Arduino is on and steady.

The plugin on the XBMC GUI says it has successfully connected to boblight, but the LED does not light up at all!

Any ideas? I'm running out of possible options here.

if it helps, this is my boblight.conf:

Code:

and here is the code on my Arduino:

Code:

void setup()
{
  Serial.begin(38400);
}

  //arduno
  uint8_t outputs[] = {9, 10, 11};

#define NROUTPUTS (sizeof(outputs))
uint8_t values[NROUTPUTS];

void loop()
{
  WaitForPrefix();

  for (uint8_t i = 0; i < NROUTPUTS; i++)
  {
    while(!Serial.available());
    values[i] = Serial.read();
  }

  for (uint8_t i = 0; i < NROUTPUTS; i++)
    analogWrite(outputs[i], values[i]);
}

//boblightd needs to send 0×55 0xAA before sending the channel bytes
void WaitForPrefix()
{
  uint8_t first=0, second=0;
  while (second !=0x55 || first !=0xAA);
  {
    while (!Serial.available());
    second = first;
    first = Serial.read();
  }
}

activate debug log in boblight.conf and see if the correct data is sent.

it even happens when using the sample config from boblight trunk which is automatically added to the squashfs image by the build system.

EDIT: I know that I should take ttyUSB0, but it should at least find the [DEVICE] section, doesn´t it?

Are the read permissions for boblight.conf set correctly?
