An STM32F446RE mini handheld Pong project derived from the JAARK controller hardware.
- MCU: STM32F446RETx
- Display: ST7789 over SPI2
- Player 1 paddle: ADC1 joystick axis
- Player 2 paddle: ADC2 joystick axis
Open STM32_PONG_HANDHELD in STM32CubeIDE as an existing project, then build and flash with ST-Link.
The firmware keeps the controller display and joystick pinout, but removes the JAARK Bluetooth/watchdog behavior. Both joystick axes control separate Pong paddles on the 240x240 display.
