Just working with this today: Hack a PICstart Pluss or (insert youir favorite programmer here) to program these parts in-circuit. All MCHIP parts except some really old 16C5x's (if I am not mistaken) actually use a serial protocol. I make an adapter out of a 28 pin DIP socket (which goes into the programmer) and an appropriate header (to match the one I design into my board) and wire the MCLR, ground, RB7 and RB6 from the progger to the board. I then add a little 5V power supply to the mess which plugs into the +5 volt bus of my board. Yes this has to power your board during programming, and no your programmer won't power your board with it's internal 5V unless it cost a lot of money. MCHIP will tell you this is not recommended with a PICstart plus, but we PIClist hackers know better. --Lawrence ----- Original Message ----- From: "Pic Dude" To: Sent: Thursday, May 30, 2002 2:22 AM Subject: [PIC] / [EE]: Speaking of small... > Thinking of playing with the PIC16F872 in 0.050 SO format, instead > of the .3 DIP that I use currently. 3 major considerations are: > > (1) Being able to solder these -- I think it's doable with a nice > small soldering iron. > > (2) Not being able to re-program once it's soldered on the board, > but I'll look into ICSP...later. > > (3) Finding some way to program the chip.
