Post by thread:(OPS!!! Forget "Baldas"!) & (Capacitors from Vdd t

Sorry!! Sorry!! It's friday! I'm sorry! As you may guess, I sent the mail with subject "Baldas" to the wrong address... Please Ignore. I need some coffee... Anyway, since I'm here, just one little question: I'm building an ISA Card with a PIC 16c64. Communication with the PC will be done by 16bit I/O through 2 FIFOs. This Card is supposed to be connected to a CAN bus, and that's it's primary purpose. Unfortunatly this won't be done. We needed the i82527, and it's not available. So, this card will just have a PIC with time-stamping to play with. My question is a simple one, I think: Should we put 10nf Capacitors from Vdd to Vss pins? This is supposed to minimize noise glitches. I just would like to be sure if it's not going to be a problem... Thanx, Nuno. -- .^. _,^,_ /\ ___( | )_____ Nuno Filipe Freitas Pedrosa __________ o(`} | , __/\/ /__ /*\\|//*\ SIEMENS S.A.
