Hello, I am fairly new to the world ofmicrocontrollers, and I was wondering if anyone had ever thought about converting the MIDI code which comes from the sound card on some pc's to something which may be heard. Which is what I am trying right now. I want to have the pic play monophonically, so I need only worry about one note at a time. I am trying to only have one output bit, which is a square wave set to the frequency of the note. Setting the volume of the note can be done later, butnow I am stuck, because I don't know if the pin on the sound card can be connected directly to the uart onthe PIC. If anyone can shed some light on my problem,it would be greatly appreciated. Thank you in advance Michael Waits __________________________________________________ Do You Yahoo!? Yahoo!
