You need to be Yahoo member to enter.
The question was
display radio on pc how?
Answer that I got:
The I-Bus analyser recieves the data over the serial port, so you just need
to add the COMM control to your VB program, recieve the raw I-Bus data from
the serial port and then decode the protocol yourself in vb. There's plenty
of info around on the offsets that contain certain data within the I-Bus
data packets...
I realy starting to believe that this is a good solution for a car pc solution.
The sound goes direct to boxes and we can also conect the Carpc sound to it, we can also use the BMW DSP and so one...
What do You Think???
