4. Developer Environment

We   can   use   Keil   MDK   (Microcontroller   Development   Kit)   to   develop

(coding, flashing and debugging) our own code which is based on SW SDK
provide by AcSiP.

MDK Core

MDK Core includes all the components that you need to create, build,

and   debug   an   embedded   application   for   Cortex-M   processor   based
microcontroller devices. The  Pack Installer manages  Software  Packs that
can be added any time to MDK Core. This makes new device support and
middleware updates independent from the toolchain.
