ICSP Newbie

Sorry, no offense meant

None taken. Just stating facts. I welcome people pulling my schematics or code apart - I can learn from that as much as anyone else.

Does the forward voltage drop of the PIC's supply isolating diode not cause any problems?

Since I don't know what you're doing with your 5v rail, it's impossible to comment. If you're running ADC's and VRef is strapped to Vdd then sure you will have to compensate for that in your design.

Life is a compromise.

It all depends what you're building. If it's a one-off prototype for your own play, then shove a DPDT switch or Relay on the board instead of my Diode solution. Ugly, but no losses there (other than in PCB Real-Estate and Money). If it's a production PCB, then what are you doing with ICSP anyway?... you're just adding unnescessary expense, and if you must, then as I previously said, you will have compensated in your circuit design appropriately.

icsp is good for future upgrades if the pic isnt removable.

also, i read somwhere in here that some people just use a jumper to go into program or execute mode. looks nice and people wont mess with that like they might a button.

melanie sure shoots em down.
