I am just about to start a journey as embedded software developer, and I am trying to familiarize myself with a STM32L1 discovery kit - the initial feeling is one of bewilderment.

After I successfully attached the board to my laptop and ran the "Press a button to ...." tests my plan was to proceed to the source code of the demo application:

1. To read through the source code to familiarize with it.
2. To compile it on my laptop
3. To flash ti again on the devkit.

I was expecting to find the code e.g. as a zip file or a GitHub repository - but I I can not even find the code? I am most familar with Linux and my intention was to develop on that platform using gcc (arm-none-eabi-gcc)?

I do not really understand what this dialogue wants me to do - but whatever I click on nothing happens. Hard work ;-(
