That example was for XC16 specifically, but I can also help with XC32.
These are both GCC (General Cross Compiler), and you already have the absolute right to use unrestricted, fully unlocked versions of them for free,
so long as you agree to the GNU license terms and conditions.

I can’t say the same of XC8, and can’t help with that either in public or private.
That said, they are both C, and it wouldn’t be a huge jump to use XC16 with a 16 bit pic.
Select the right device and you get zero overhead looping.

Mods/Admin may feel uncomfortable about this kind of thing as it is, and if so, I guess it will be deleted,
which is ok, but it won’t be because posting it was the wrong thing to do.

I told Microchip exactly why I cancelled my paid XC16 subscription, and received no reply. Were I ever to hear anything from them I didn’t like,
I’d run straight to the Free Software Foundation, who have the time, money, resource, and willingness to pound Microchip’s legal team into the mud.
