Talk:Serial ICSP programing

From Organic Design

Question: Do you need capacitors/resistors in between the lines of the serial port and the lines of the micro? Perhaps it's safer to have some kind of buffer? --Rob 12:37, 26 Mar 2007 (NZST)

Capacitance is what you want to remove from your signals, if you want to protect it just put each input through a buffer (ie a logic gate which does nothing like two inverters in series, or an and/or gate with its inputs tied together - or you can just get a buffer chip). Use a logic family which has quite a wide voltage range like 74HCxx. --Nad 13:19, 26 Mar 2007 (NZST)
