Hello everybody. I'm new to freescale microcontrollers and working on a new project with a K20 72MHz device. I bought a FRDM-K20D50M board which I know isn't produced anymore by Freescale. I know the K20 itself is not currently supported by the SDK but am wondering about which is the closest supported device to this one that I can start a project with and what basic modifications would be needed to port it to this device. I'm guessing it's the K22 but wanted to ask here. I'm planning on using Kinetis Design Studio as well. Just looking for a good starting point for this part, especially since I will be utilizing USB so I would like to find some good code base to start.
