#146975 - Are you allowed to open the clock? Responding to: ???'s previous message |
If so, first see Aubrey Kagan's suggestion and check for a 50/60Hz setting:
http://www.8052.com/forumchat/read.phtml?id=146967 If no luck with that, then just generate a low-voltage 60Hz feed to the appropriate input on the chip - no need to mess about with generating 120VAC!! |
