A bouncing balls demo using the multicore features of the Raspberry Pi Pico. Requires the PicoGraphics library to display on a 240x240 LCD SPI screen.
- Uses core0 to maintain a draw loop and handle screen updates
- Uses core1 to maintain the balls and calculate the physics

Copy bouncyballs.py and main.py to your Pico and restart.
- Change
MULTICOREto enable or disable the second core. - Update the ball settings and number to suit
With 1 ball still can't get a display frame rate above 22 fps.
- Collision detection and bounce
- Optimising code for maximum efficiency
- Why is frame rate capped at 22fps?
Tried some optimising :
- Calculation and render on a single core - 12fps
- Multi core - Render = 15fps | Calc = 25fps
- Swapped OO classes for simple function calls on a list of ball data - Render = 15fps | Calc = 100fps (4 times faster not using OO)
- Swapped function calls for inline code - Render = 16fps | Calc = 125fps
Example code in main-simple.py and main-simple-multicoreonly.py
