Below there are explanations on how to use the example n.1 (running on STM32F4-Discovery) used during the:
SILICA ITALY STDay 2011
STM32F4-Discovery exe1 explain how to use Atollic, I/O, Interrupt, TIM3, TIM4, MEMS used for mouse emulation, USB, etc.


Hand's On
  • We suppose that the example is in the:
    C:\ESEMPI-SW\STM32F4\Exe1-HandsOn2011
  • Run ATOLLIC v.2.2 or higher
  • From the ATOLLIC Workspace Launcher in the box Workspace select:


  • From the new page that appears click on: Start using TrueSTUDIO


  • Now we are inside the ATOLLIC IDE. From File menu select Import


  • From the Import box select:
    General->Existing Projects into Workspace
    and press Next


  • From the new page that appears choose:
    Select archive file
    Click on Browse button and select the file Ex1_-_Demo_on_STM32F4-Discovery_-_solution_v2.zip

    Now press Finish button.

  • Now the ATOLLIC import, inside the workspace, the project and compile it.
    Press on the Console button and you must see something similar to image below


  • For use FPU see below


  • Now is necessary configure the Debugger, for do this make sure to have select your project (see below)


  • next select the Debug Configurations (see below)

    and from the new windows that appears chose F4_demo.elf (see below) and from the Debugger tab make sure that are selected:
    ST-LINK, Autostart local GDB server and SWD interface (see below).
    If all is OK press Close button but if you do some modifications before to exit press Apply Button and next Close button.


  • For start the Debug press the Debug icon, see below


  • Main Debug commands
    • RUN or RESUME icon, see below


    • Restart Program icon, see below


    • PAUSE icon, see below


    • END Debug icon, see below


    • ADD/REMOVE breakpoint double click on line number

    • Remove ALL breakpoint icon, see below


    • To add variables to be watched -> drag&drop its name to Expressions tab or right click mouse on variable and select “Add watch expression”, see below


    • All necessary information concerning the registers of the peripherals is available (reset state, address, current value, bits value and the description), see below.


    • It is possible to track changes in core registers -> Registers tab (any change is reported by yellow highlight), see below.


    • Debug Bar is below



  • The Ex1_-_Demo_on_STM32F4-Discovery_-_solution_v2.zip does this


    To switch from one functionality to another press the BLUE button that is present on the STM32F4-Discovery.
    To use the MEMS_MOUSE emulation connect the STM32F4-Discovery MICRO USB to the PC.
