ICSP (2) questions

[mister_e]

Fair enough for me. But you could still build your own adapter for few bucks... BUT you will spend time on it.. so there will be no money saving at the end.

So... Go for it.... even it's kinda weird that the adapter is more expensive than the programmer

Still possible to hack this 12USD board

But add the shipping etc etc... not sure if it worth it. maybe easier to use though.... not jumper, no nothing.

Micros usual price.

But that does not set you up for ICSP. You will want that. With the ZIF you will plug the chip in, program, remove the chip and have another ZIF on the bread board or on your PCB, plug the chip in there. Find out the config is wrong or something else. Remove the chip from the test circuit, put back into the programming soket and start all over.

With the PICKIT2 all you need is a bread board and one of these http://www.allelectronics.com/cgi-bi..._SPACING_.html

Break off the friction lock so the PICKIT2 will fit on. Now everything stays on the bread board. The chip will not need to be removed for programming.

Look at chapter #3 http://ww1.microchip.com/downloads/e...Doc/51553E.pdf

So in my opinion, only by the PICKIT2 and use the other money for parts that will not end up collecting dust. I have a large dust collecting collection myself.

mr-E : the 12 USD card seems to require some "Programmer" (there is such a connector on the board", and the picture says "PICFLASH-2" ... What is the cost of this piece ?

MackRackit : I also do have some dust at home ! Let me read chapter 3 before asking how can I do this magic. In fact, I have no "final" board, just playing at home, so the "plug-here", "unplug-and-move-there" is not such a problem to me .... (;-)) .. yet.

THANKS a LOT all (both) of you ! Ramon.

As i said, this has to be hacked before using it... but... hummm.. it will only need +5V, GND, PGD, PGC, VDD signals... the same as PICKIT2 will provide.

It doesn't worth to invest for PICFlash programmer.

Real ICSP is more valuable... unless you want to program your PIC... then ship them without any PCB. Who want to ship something without testing it? well... not me Hence why the ICSP is handy... at very least for me.

[Ramonetnet]

Well, let me explain a bit my environment. I am not in a "industrial" situation.
We want to build a solar intensity detector, so the solar cell provides some analog voltage, the PIC converts it to digital, a PC reads it using the parallel port, and starts/stops few motors to try to find a better position. It is a scholar project, so only one prototype has to be built.

So, I think I need a LVP, if possible, or the people at Microchip will be happy with my 57,89 €.

The In-Circuit-Programming is not so important to me ...

Thanks for you patience. Ramon.

[mackrackit]

The In Circuit Programming is up to you, we were just letting you know the options.

Your project is a good one. I am not sure what you mean by LVP though.

Another thought... Serial communications are much easier than parallel and if the devices are a distance apart serial will work better.

ok so let's have this discussion in few weeks... Once you'll have swap your PIC from Board to programmer, and programmer to board few dozen or hundreds times...
