Hi, http://www.semiconductors.philips.com/pip/PCA9564BS.html So far as I can tell no one is working on a driver for this chip, or anything like it, if I am wrong please let me know. We have an upcoming PC104 product which will include this part so I will be working on algo and bus drivers over the next few days. Cheers, Ian. -- Ian Campbell, Senior Design Engineer Web: http://www.arcom.com Arcom, Clifton Road, Direct: +44 (0)1223 403 465 Cambridge CB1 7EA, United Kingdom Phone: +44 (0)1223 411 200 _____________________________________________________________________ The message in this transmission is sent in confidence for the attention of the addressee only and should not be disclosed to any other party.
