While there are several commercial toy grade FFB steering wheels and some higher end simulator grade producs these are very expensive and and are often not moddable or come with their own expensive ecosystem.
It makes sense to focus this project on a simple open source force feedback interface as this is the part where the community lacks a good and open solution.
Therefore the main goal will be to develop a universal FFB controller (Open FFBoard).
It will provide a modular architecture and interfaces with multiple motor drivers and a reference motor driver board based on the TMC4671.
The FFBoard is just an interface for USB HID, encoders, buttons and pedals. It can interface with almost any sensor or motor.
The software is modifiable for different motor drivers and control outputs.
Currently supported motor drivers: - FFBoard TMC4671 - ODrive (CAN) - VESC (CAN) - PWM (centered, pwm+dir, RC ppm, dual PWM)
Currently supported encoders: - ABN incremental (PWM) - BISS-C (PWM, TMC, requires external transceivers to SPI3) - MT6825 (PWM, TMC) - Encoders supported by VESC and ODrive - SinCos (TMC)
