This may seem like a stupid question but why does my PIC reset from noise on Vcc? The noise is generated by the flip of a switch that connects or disconnects Vcc to a 74VHC125, NC7S14, & 93C86. I have .1uf caps across the power supply at each chip including the PIC. The MCLR is tied to Vcc with a 1K ohm resistor. I don't have a oscope handy to look at the Vcc line right now. Am I missing something... -- http://www.piclist.com#nomail Going offline? Don't AutoReply us! email listserv@mitvma.mit.edu with SET PICList DIGEST in the body
