I have a newbie question, I am learning about the M3/M4 processor and need to get started with an IDE and a controller. I have the MK20DX256 processor already and downloaded the MCUXpresso IDE but can't seem to find the SDK for this processor. Is there a "getting started" help doc or video I can look at? What do I need to initialize this microcontroller so all the registers are setup and ready for code to written?
I did read that the MCUXpresso doesn't support the K20 family but that was last year and I was hoping this has been changed.
***Side Note*** I have a Teensy 3.1 microcontroller that uses this processor so I am using that since it already has the USB connection along with breakout pins. I know I can use the Arduino IDE but it is very limited on its capabilities.
