Abstract

This paper proposes a system architecture based on MCU and FPGA that supports the control of dozens of stepper motors, characterized by low cost, high real-time performance, and ease of implementation. The system leverages the integrated floating-point unit in the MCU, along with its rich peripherals and ease of development, combined with the parallel processing capabilities and abundant I/O resources of the FPGA. Additionally, to address various complex scenarios in medical devices, an asymmetric trapezoidal velocity profile is implemented on the FPGA with minimal resource consumption of 528 LUTs and 353 Flip-Flops. Finally, the feasibility of the circuit is validated through logic waveform capture and oscilloscope measurements, and position error tests on actual stepper motors demonstrate that the system is suitable for most applications.
