Yes, is true and a very good point.  The problem is that the =

platform, allows to deploy complex applications in lesser =

at least according to my point of view.

Of course, you are right.  I still think that the PIC32 is =

an excellent 32bit microcontroller, I was just wondering =

about it being a so good device, it could take advantage of =

applications like those delivered with a linux inside.

Having or not a embedded linux, the PIC32 came to stay, and =

with its aggressive price will give a tough market fight.
