From the project

Compact FOC motor controller firmware + hardware (STSPIN32G4 + MT6701 + CAN-FD) for QDD actuators

Compact Field-Oriented Control (FOC) firmware and hardware for QDD actuators

SiPDrive is an open-source motor controller built around the STSPIN32G4 System-in-Package, MT6701 magnetic encoder, and CAN-FD communication. It targets compact quasi-direct-drive (QDD) actuator applications with torque, position, and speed control.

- 40 kHz FOC current loop with hardware CORDIC acceleration - CAN-FD command/telemetry (1 Mbps nominal, 5 Mbps data) - Current and position control modes - 14-bit magnetic encoder (MT6701 SSI/ABZ selectable via solder jumper) - On-device encoder calibration with…
