hey

ive joined this group right now to get a little help on the project im working on right now. My deadline is due and we dont have a working project!! we are trying to send files thru the telephone line via a transciever card , so its PC to PC communication via the telephone line. I found this ic on the net n it did all the functions that we had seperately designed modules for.....like DTMF generation n detection, off -cradle, psk modulation......so we went ahead n got this ic from its manufacturers as it was not available commercially..........n now we havin problems coding the microcontroller to run this ic. so if anyone could mail in their solutions asap would be appreciated !!!!!
