I've never seen it as you've described above. My datasheet shows an example connection and it doesn't include a resistor anywhere. Leave the resistor out completely and you'll be fine. --Andrew _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com -- http://www.piclist.com#nomail Going offline?
