FreeJoy

FreeJoy is a customizable gaming device controller based on the low-cost STM32F103C8 microcontroller. It allows you to create your own HOTAS-systems (sticks, throttles, various expansion panels), pedals, car control systems (steering wheels, pedals, gearbox shifters, etc.) and configure the designed device.

Features:

  • Up to 8 - analog axes (output resolution 12 bits);
  • Up to 128 buttons or toggle switches;
  • Up to 4 HAT switches;
  • Up to 16 incremental encoders (1 high-resolution encoder);
  • Ability to assign button presses to certain positions of the analog axis (up to 12 buttons per axis);
  • Support for shift registers 74HC165 and CD4021 to increase the number of connected buttons;
  • Support for digital Hall sensors TLE5010/TLE5011, TLE5012B, AS5048A, AS5600, MLX90393 (only SPI interface);
  • Support for external ADCs ADS1115 and MCP3201/02/04/08;
  • 4 channels PWM for backlight control;
  • 24 LEDs (single or in the matrix), mapped to the states of the buttons;
  • Setting the device name and other USB parameters;
  • Convenient utility for configuration;
  • Upgrade firmware via USB;
  • Save and load device configuration from file.

Axes:

FreeJoy supports up to 8 axes. Analog inputs (potentiometers, hall sensors) on the A0-A7 terminals, digital sensors (TLE5010/5011, AS5600, MLX90393), or external ADCs (ADS1115 and MCP3201/02/04/08) can be used as sources for the axes. All axes have the following settings:

  • Source/destination of the axis (X, Y, Z, Rx, Ry, Rz, Slider1, Slider2);
  • Enable/disable axis output;
  • Resolution;
  • Calibration (manual / automatic);
  • Smoothing (off or 7 levels of filter settings);
  • Inversion;
  • Dynamic or center deadband;
  • Axis offset (magnet offset);
  • Response curves;
  • Axis from buttons/encoders;
  • Trimming axis by buttons
  • Axis prescaler
  • Ability to generate button presses in certain axis positions (up to 12 sections).
  • Combined axes functions

Buttons:

FreeJoy supports up to 128 buttons connected as single buttons (shorting the signal contact to GND or VCC), as a matrix of buttons, via shift registers or through the axis-to-button function. Buttons can be configured as:

  • Normal button;
  • Inverted button;
  • Toggle switch on/off;
  • Toggle switch on;
  • Toggle switch off;
  • HAT switch;
  • Input incremental encoder;
  • Radiobutton;
  • Sequential button;
  • Sequential toggle button
  • 5 shift modificators.

For setting up your device configurator utility is required. Download latest release and run the installer.
