Part Number:CC2650
This is a very basic question perhaps, but i just can't seem to wrap my head around using Code Composer Studio or Eclipse for that matter. All i can do is run existing examples.
What i want to do is very simple - Take an existing Bluetooth based example like "simple_broadcaster" and then add more code to it so that i can maybe blink some LEDs, use some I2C sensors, basically use GPIOs, UART etc. I realize that even in the BLE example the "Drivers" are there as i can see in the picture, but i don't know where exactly to write new code to use those drivers. 
TO ELABORATE MORE : There are also some examples in the RTOS that only use GPIOs or "Non-Bluetooth" based functionality like PWM, UART etc. What i want to know is how do i add these two i.e lets say i start from "simple_broadcaster" then -
Q1) Where and how do i write code so that i can do something with GPIOs ? How do i make sure that it gets built without errors?
Q2) How will it be included during compiling? What things should i take care of ?
