New to ARM - nRF51 DK (Nordic)

Hello,

I am relatively new to ARM, I recently acquired Nordic Semiconductors nRF51 Development Kit (DK) ( https://www.nordicsemi.com/eng/Products/nRF51-DK ) which runs its examples on ARM mbed with Keil uVision. I have had experience more recently and frequently working with the Arduino side of things, and I really want to be able to understand what's going on in the code present on the ARM examples for the nRF51 DK, and be able to start writing simple communication code, etc.

I also am curious what the best way to interface with various LCD screens, or I2C sensors would be.

I know ARM is capable of doing all of this, but I have no idea where to start - I need to be able to:

1 Display info on an LCD screen (16 pin Serial or I2C) 2 Read a Rotary Encoder (2 bit grey code or quadrature) 3 Read Various sensors (analog voltage measurements) and change outputs accordingly. 4 Set up wireless communication between two devices 5 Establish Bluetooth communication with phones, etc.

I have gone through some of the basic examples and found it helpful, but lacking explanation of the code, and I'm not overly familiar with it. If anyone can direct me towards some beginning guidance to get me started with any of these - it would be much appreciated.

I apologize for such a broad question but I figure this is the best place to put it!

Thanks and Regards,

Jengil
