AVR-Chat

What is your development environment?  That might make a big difference on
which programmer to use.  Avrdude, which comes with the WinAvr (GCC C
compiler) works with a variety of programmers including some "no parts" ones
like the SAMPLE programmer I supply with my ARC boards (www.barello.net/ARC)
You can see the schematic in the users guide.  If you want you can dispense
with the resistors and just use an old LPT cable, cut & the proper wires
brought out to your programming header.  Works great.  PC only.

Oh, yeah, the SAMPLE programmer is what BASCOM uses...  Pretty slick.  I
recommend it for getting started.  It makes stuff like serial I/O and LCD
and one wire stuff very easy.

Cheers!

Hi All,

I have been reviewing the archives to get an idea of a simple way to
program some chips.

As it is now, I am just getting started and an not looking for the
most universal, but the best cheap unit, even if it limits my chip
selections.

I'm hoping there is some simple programmer that can be assembeled by
the average parts bin we typically have.  (some scattered on the
bench, others still in boards yet to be sacrificed and others in
those neat little baggies from the suppliers)

As you probably know, I'm doing a little reading on the C language
and have considdered dabbling with FastAVR or Basicom as a way to get
things happening faster.

>From the little that I could really understand about programmers,
there are serial, parallel and USB, with USB being rare.

Then there is ISP which is fine with me as I would rather make a
board for testing than to move chips around.

But to get started, I'm hoping to put together a simple board with a
uC a couple outputs and a couple inputs and a serial cable for use
with I2C or SPI as the case may be.

At this point, I don't need to worry about programming any other
chips like e-proms or the like.

Any suggestions ?

Dave
