Macegr was kind enough to send me a plugin for winamp that would send data via the serial port  with the SSC format. this is the code i'm trying to build so i can get an led to pulse to music.

the first part is a small log of what winamp is sending out. When i use the serial monitor and input "ÿò........." or "ÿò" it takes the first one off which is 255 of and reads and prints the second value. in this case it's 242.  and the led turns on. but when winamp is sending out the data nothing happens..

i do know that i have the plugin configured to the right port because i've had mixed results in the past with the led blinking but not working correctly.. and when i would stop the plugin the light would turn off instantly.

any information you could share would be helpful.

thanks for your time,
Dave.

Are you trying to actually see the data that Serial.print is supposed to echo? Because that might be your problem...if you load the Arduino program and then open the serial monitor, the Winamp plugin will not be able to connect to the same serial port. So you'll need to make sure that the Arduino serial monitor is never running when the plugin is running, and that the plugin is never running whenever you try to program the Arduino.

I also notice that your Serial.begin(9600) doesn't match with the 57600 that was set in the plugin as I sent it to you. If you haven't changed that in the plugin sourcecode, then you might try changing your Arduino code to Serial.begin(57600) instead.

o yes i should has said somthing about that..  i do close the serial monitor when i try to test with winamp and the other way around..  and the "prints" were just there for testing with the serial moniter.. i comment them out when i try to get it working with winamp..

as for the rate.. i'm not sure so i'll go check that out..

thanks macegr.

 ;D ;D well don't i feel like a dumbass.

this whole time it was 57600    

it's working now,  now i'm going to fine tune it and smooth it out.

macegr, you're my hero buddy.  ;D

Awesome, be sure to take a video and let us see how it works!

Macegr, can you help me to compile your plugin, I have a legal copy of visual studio professional, and I have Qt too if needed, can you just send the compiled files?
