An implementation of the Playstation 1 Doom fire effect on an STM32F429 microcontroller, reacting to board movement:
Read how the Doom fire was done in an article by Fabien Sanglard:
Overall this is pretty useless, but you can use it as a desktop ornament (if you have a spare STM32429DISC1 discovery kit lying around) Press the blue user button to stop the fire temporarily.
- Fire is reacting to movement (by reading gyroscope data)
- Full TFT resolution (measly 320x240 though) but running at stable 60 Hz
- CPU is idle for a good part of the 60 Hz frametime and put into low-power mode
- ChromART (DMA2D) is used to speed up the drawing
Just flash Release/DoomfireSTM32.elf to the STM32F429DISC1 discovery board via
USB, e.g. with the STM32 ST-LINK utility or the STM32CubeProgrammer.
The STM32CubeIDE workspace (Eclipse) project files are included.
The main code is in Core/Src/main.c plus a big load of boilerplate code.
