I've used a similar scheme, only for ICSP. On my newer circuits, I include a SIP header that connects to RB6/7, !MCLR, +5 and ground. I have a cable from the homebrew programmer to the matching plug - same game, DIP header on the programmer end. All it takes is a diode to protect the circuit from the +12 (I'm using high voltage programming) and a little care on how RB6/7 are loaded. Sure beats plugging and unplugging chips when testing, and of course, makes life a whole bunch easier with the SMT devices. The PIC-EL board associated with the Elmer 160 PIC course is similar. In that case, we actually provide matching SIP headers and a jumper plug. That way the onboard programmer can be used for the students' later projects, and folks who don't have a free serial port have a connector to bring in the lines from their parallel/USB programmer. 72/73 de WB8RCR http://www.qsl.net/wb8rcr didileydadidah QRP-L #1446 Code Warriors #35 ----- Original Message ----- From: "Tom Deutschman" To: Sent: Monday, December 08, 2003 3:10 PM Subject: Re: [PIC]: ICSP advice needed... > > > > I have been using my trusty old PICStart plus for quite some > > time now, and am interested in starting to do ICSP instead, > > so I can start using some surface mount parts. > > In the past, I've programmed surface mount PICs with the PICStart Plus > by building a cable with a dip header on one end and a SIOC-Clip on the > other.
