Version 2.7.0-201611282115 is a new release, adding support for active graphical buttons.

Download​

The binary files are available from GitHub Releases.

Changes​

As the old version 1.2 of the SDL graphical library was less and less supported, the build procedure was updated to use SDL2.

New features​

  • the most compelling new feature is the addition of active graphical buttons; the rectangles around the buttons are sensitive, and moving the mouse over them changes the cursor to a hand; clicking the buttons is also functional, the Reset button triggers a board reset; the user button is also connected to the corresponding GPIO pin, and can be checked by reading the GPIO pin input value; it is also possible to configure the EXTI device to trigger interrupts on GPIO pin changes;
  • ths STM32 implementation was extended to support the EXTI and the SYSCFG peripherals; now it is possible to trigger interrupts on GPIO pin changes;
  • the debug options were extended with two new trace options, func and mr (use them after -d).

Known problems​

  • the graphical buttons are currently available only for the STM32F4DISCOVERY board (the user button is connected to GPIO A0); more boards will be added in future versions;
  • Ctrl-C does not interrupt the execution if the --nographic option is used.

How to test the buttons​

An Eclipse project that can be used to test the STM32F4DISCOVERY button is available from

https://github.com/gnu-mcu-eclipse/eclipse-qemu-test-projects/tree/master/f407-disc-birq

To use it, clone the gnuarmeclipse/eclipse-qemu-test-projects git and import the f407-disc-birq project. Build and run the application; the four coloured LEDs will lit for a second, then turn off; click the blue button; the LEDs will lit one by one. Click the black button; the board will reset.

Download​

The new QEMU can be downloaded from the GitHub Releases page.
