PIC do all that AVR do ?

is there ny diffrence in AVR and PIC ?
i think this r the two micos most pple like
y most of pple using avr than pic
is that becoz of its price
or easy
i think the main disadvantage of PIC is that a simple
programmer will cost a heavy price

No way, you can build yourself a PIC 'El-Cheapo'
programmer for less than $ 5,-

AVR is even cheaper - DB25M and two resistors for an in-system programmer.

I think the main disadvantage of the AVR is that it costs more for
similar parts. Often more than $1.00 a chip more.

Oddly the Tiny11 sells at Digi-Key for 54 cents and may be the lowest
cost of micro-controllers.

In general, I think the AVR may be the more
capable processor. However, the PIC may be
more easily used, to begin with. The
PIC18Fxxx series probably is as capable as
the AVR.

The PIC has 36 instructions or so,
and a single Interrupt vector.

I started out with PBasic for the BS2, then
MBasic for the Atom, then MBasic Pro for the
PIC. Those have very nice modules and very
nice debuggers. Having been used to the
6502, I was shocked at how limited the PIC
instruction set was. However, they clock at
20 Mhz (instead of the 6502 1 or 2 Mhz), and
they have on-chip RAM and FLASH rom. So I
used them.

I then purchased the AVR STK-500 to use with
the AVR. I havn't yet found as nice a package
or as much support as Parallax or BasicMicro.
Compilers are more limited. Packages are more
limited. So I don't hav as much experience with
the AVR as I'd like. Your mileage may vary
(YMMV).

The cost of the programmer is about the same
between the chips, by the way.

25c for 1250 pcs.

One thing that some PICs can do that no AVRs can do is DAC. A
programmable voltage reference with no external parts.

I am pretty new to PIC as well. I am pretty surprised at the cost of a C compiler. There is PIC-lite for some of the chips, but not for the PIC18xxxx. I think the AVR might be alot cheaper there and maybe free with the GNU.

Lemme know your address and I'll send you $10.00 for 40 and some
extra for shipping !

A bulk buy was organised recently, and several of us got them at that price.
I got 50, but I need them.
