Hi Bert and Mike,

The information that you have regarding the TDA18218, where can I get my
hands on that? It would be interesting to take a shot at writing the
driver, but I guess I would need some pointers in the right direction.

Would it be possible to get the information from you, or is such
information freely available on the internet? Where should I start
looking?

Best regards,

//Jan
