I'm new !


so what i'm questioning, is the raspberry Pi capable of 1.) "emulate" a teensy++ 2.) let the emulated teensy access gpio, usb, usb micro ?
I don't see any reasons , except that the 'teensy' would not be able to use the usb's.
please provide some insight , i'm kind of lost why this hasnt been done before

Thanks in advance,
