STM32 MCUs Programming

mparmpas122321

Hello!

I am trying to get started with the programming of STM32 MCUs. I have bought a Nucleo board which has a STM32F411RE MCU on it. I have downloaded the Keil ARM MDK development environment. I have studied the datasheet of the STM32F411RE. I am going to read the Programming Manual but i was just wondering if there are any guides or manuals that can show some stuff to get you started. I would really apreciate it, If anyone has some experience on STM32 - Arm programming and could help me . image

  • Thanks for your replies people. But let me state it differently.

    Suppose i have Keil MDK or Em::Blocks. What to do next? Should i program them in assembly or in C (C++)? And what libraries are there for C and C++?

    For example i am currently using mbed library to build my projects. Are there other options available?

    Hi Manos,

     

    Programming in assembly for ARM is something that I wouldn't recommend, as you wouldn't be able to easily profit from upgrading or downgrading to other ARM architectures (Cortex-M0 uses a subset of Cortex-M3).

    mbed is a good platform (using it myself a lot too). Because it is open source you could use the functions of mbed in your new program as well; you might have a hard time to strip all the layers that mbed uses to get all hardware to work with their libraries, but the code is available (look in the mbed-src repository).

    For STM32, for each series (F05x,F1..., F3..) there's  a Standard Peripheral Library (google it with your chip's part number). The standard peripheral library is a very fast way to get peripherals working, with easy functions to enable or disable features of peripherals. They're not as high level as mbed, which means you get a lot of control, but you'll have to keep the reference manual of your chip opened to read which function does what. The Standard Peripheral Library is ANSI-C, not C++.

    Thank you vsluiter. I think this is the answer i was looking for. image

    If you have Keil allready install. You can browse into the example bundle and find a suited example to match with your MCU.

    I did that to start learning STM32 on a discovery board.

    It does inclue all necessaries library and do the blink thing.

    From there it is already much easier to get started.
