I have found problems to get the right parts.

Jesus

Jesus,

You can also use the LT1073CN8. This one has an adjustable output voltage by
using two resistors.

See: http://search.digikey.com/scripts/DkSearch/dksus.dll?Cat=2556570&k=LT1073

Thank you @groundloop!

I dont know if it makes a difference.
The one I bought originally was LT1073CN8-12

This other replacements, maybe, are not as effective.

Now I have decisions to make and experiments to do.

@digikey

Just one LT1073 piece and the shipping cost was about 40 dollars.

I got a good deal for three for less than 40 dollars at the factory.

While experimenting with the pickit-2 programer I got to the reality that it does not program the pic16f88.

I reread the information I got and found that the thing only programs 8, 14 and 20 pin flash devices.

I will find a solution.

Hi Jesus,  it does,  see:   http://www.youtube.com/watch?v=HVQ4tj-D8jM&feature=relmfu

Perhaps you use the "low Pin count demo" board which does not.

Thank you @itsu!!!

I will give it a try.  I have problems understanding the explanations on the video because it has an eco on the words you say.

The circuit you draw has only the mclr connection, I have to figure out the others.

That is a great help from you.
Thanks again!!!

Jesus

Jesus,

Find a 18 pin IC socket. Solder wires to a little connector that
fits in your PicKit2 socket. Download the PicKit2 software
programmer. And there you go.

I just finished a schematic with what I understood from the posted video and wanted to know if it was correct.

But it seems that the one you posted is easier to accomplish.

By the way is it correct?

Hi Jesus,


be aware, the video i pointed at is not mine!
I too am learning to programm PIC's with the pickit 2, and ran into this video when googling.

This video is a tutorial on how to programm with a pickit 2 "in circuit", meaning to programm a pic when it is already incorperated into a circuit (here a circuit to blink a led).
Its called ICSP (In Circuit Serial Programming), look it up in your pickit 2 users guide.

Your drawing looks ok to me.


When you ONLY want to load your PIC (standalone, so without being in the circuit), then you can use the setup given by Groundloop.
Use the pickit 2 programm, and load (write) your hex file into the Pic, then "move" your pic into the circuit you have designed and it should work.

Good luck,  regards Itsu.

I sent for the rest of the parts. The list and the code numbers are on the graphic, just in case somebody needs it.

Not all the parts are for this project. It is that they were waiting their turn and reached their time now.

Jesus,

Yes, but you must be sure that your external +5 volt is off when you plug in your PicKit2.
Also be sure to unplug your PicKit2 when your done programming the PIC.

I always use IC socket on the PIC because I want to reuse the PIC in other circuits.
So I bought myself a plastic case and mounted a ZIF socket onto the case. I did
put my PicKit2 inside the case. So now I have a USB based PIC programmer with
a ZIF (Zero Insertion Force) socket.

Your programer looks good!!

Jesus,

Thank you. :-)

It is an easy solution to get a PIC programmer. Just remember
that when you solder the wires on the underside of the ZIF
socket then it will look like the attached drawing.
