LPC810 mini ARM Prozessor in 8 pin dip package

Graynomad:

would it be possible to use the Arduino IDE ( for Arduino DUE ) to compile the code for the LPC810 ?

Not as it is, I think you would have to add your own variant file and core libraries but that's not an area I'm very familiar with.

It should be possible. The "Teensy" is ARM based and it manages to integrate itself.
