Hi, I want to create project with EFR32 of Silicon Labs, Is it possible with Keil?
Thanks, Oz
Yes: it's a Cortex-M4 - so it would be possible with any IDE/toolchains which supports the Cortex-M4.
However, it would probably be easiest for you to start with the IDE/toolchain(s) which SiLabs uses in all its support materials ...
See: www.silabs.com/.../bluetooth-low-energy
From the 'Getting Started' link at www.silabs.com/.../blue-gecko-bluetooth-low-energy-socs
www2.keil.com/.../learn
Anything to do with Bluetooth is really not a beginner's project, though - you'd really need to spend time getting up to speed on the basics before adding all the complications of BT/BLE.
Look to SiLabs for specific support in applying Keil to their particular products
There are plenty of device support packs listed for Silicon Labs EFR32 on http://www.keil.com/dd2/pack/ so it should be easy to start using it with MDK.
