Just got an STM32F4 discovery board.. Needing a little help :-)

Hi everyone!

I'm new to the world of microcontrollers. After some research, I bought my first ARM based Microcontroller; the STM32F4 Discovery.

Now, I have a few questions for the community, hopefully someone can answer me.

The first question has to do with the memory on the STM32F4. I was wondering if there was a way to expand the memory? Maybe have the memory on CPU, but then secondary dynamic memory (non flash) that could be added to the 192KB as extended memory.

the second question is which compiler should I start with? I normally run Ubuntu Linux 12.04, but I also have Windows on a virtual machine via Virtualbox that I'm able to load up Keil, and some of the other compilers on. I would personally like to have something that I can run on Ubuntu 12.04. Then again, I'd like to start with something that I can focus less on the software and more on the coding. I'm doing this independantly, so I'm on a budget. Which compiler would be best for me?

the third question is where should I start? I was a little confused as to what I should do first or how to set up a project. Where should I start to figure out how to code for this microcontroller? Are there any great books to read on this?

Thanks,

    Thank you Joseph! Thanks for the warm welcome as well!

    The reason I'm asking about memory is that 192KB will be a bit low for the final end product that I'd like to create. Right now, I'll be OK with it because I'm learning the architecture. When I learn design and how to interact with the chip and other components, I'd like to use the same CPU, but with a bit more memory (2 - 4MB max). Would I be able to do that with this CPU?

    I will check out the links you posted and read the documents as well. I installed Keil and TrueStudio. I'm still evaluating which product I'm going to buy.
