Is it worth using these PIC32?

(1/7) > >>

Today reviewing the components that I have I have found these PIC32 (MX795, MX460), there are quite a few as can be seen in the attached photos. Many years ago I stopped using PIC microcontrollers, to use ARM.

But now given the scarcity of components, and having found all these PIC32's around the house, I wonder if it's worth trying to use them for some projects.

The last thing I remember about the PIC32 is that the C compiler was not free, and it cost quite a lot, I think I remember around 1200 Euros, and the alternative to using the demo is that you don't have optimization enabled, which results in a code object that is twice the size and for certain parts of the program it may not work well if it is not optimized.

Ouch! You need some JEDEC trays my friend  :-+

Either use for project, or try and score some $ on ebay?

Those PIC32 that I show in the photos are from many years ago, when I was dedicated to electronics as a hobby.

Now I work professionally, I have my own Pick and Place machine with custom trays and the ARM microcontrollers I buy always come in trays from the manufacturer, although I don't use them in my P&P machine, I use the custom trays in these photos attached.

Well played! Awesome setup  :clap:

That is not true, optimization is enabled up to -O1 or -O2 (I forget which), which results in code almost as fast as -O3 or -Os, perfectly serviceable. I also prefer MplabX to any Eclipse-derived thing so it's a little more pleasant to work with.
