Version 2.8.0-201612271623 is a new release, adding support for active graphical buttons to all supported boards.

Download​

The binary files are available from GitHub Releases.

Changes​

The main internal change is the use of CMSIS SVD files to generate the peripheral registers. This ensures the best possible accuracy in the register bit-fields implementation.

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;
  • the STM32 implementation was extended to support the EXTI and the SYSCFG or AFIO peripherals; now it is possible to trigger interrupts on GPIO pin changes;
  • the STM32F0DISCOVERY board was added, as a Cortex-M0 board.

Addressed bugs​

  • [#31]: the GPIO toggling using the ODR register is now functional;
  • [#24]: command line options located after --semihosting-cmdline are no longer parsed, but passed to the application.

Known problems​

  • 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-blink

To use it, clone the gnuarmeclipse/eclipse-qemu-test-projects git and import the f407-disc-blink 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.
