【物联网设备端开发】ESP开发工具：QEMU如何模拟用户图形界面

Enabling graphical user interface (GUI)

The ESP32 QEMU implementation implements a virtual RGB panel, absent on the real hardware, that can be used to show graphical interface. It is associated to a virtual frame buffer that can be used to populate the pixels to show. It is also possible to use the target internal RAM as a frame buffer.

To enable the graphical interface, while keeping the serial output in the console, use the following command line:

build/qemu-system-xtensa \
    -machine esp32 \
    -drive file=flash_image.bin,if=mtd,format=raw
    -display sdl \
    -serial stdio

If gtk backend was enabled when compiling QEMU, it is possible to replace -display sdl with -display gtk
