This application is intended to lead to a modular design idea that combines the traditional stepper motor controller, driver, and arithmetic algorithm into a module, or For the Black Box, users do not need to understand the circuit design and program architecture in the Box. They only need to care about the interface. This interface can adapt to a variety of host (Host) controls, such as PC, MCU, FPGA, PLC. class. Black Box can do more than 95% of the work for users, users can complete the system setup quickly by completing less than 5% of the workload.
At the same time, this application also verifies the anti-interference and stability of the system of GD32 . There is no isolation between MCU and Driver. The start and stop of the motor does not affect the MCU work. At the beginning of the design, the solution was conceived from the perspective of the user, so the function was fully met with the predetermined requirements:
1, the interface is simple --- RS232 (Tx, Rx, GND)
2, the instruction is simple --- command + parameter
3, the operation is simple - command operation motor start and stop, acceleration and deceleration control
4, the structure is simple - small, with heat sink
Performance is not inferior:
1. System stability---interface isolation, overcurrent protection, high temperature shutdown
2, intelligent algorithm - automatically select trapezoidal or triangular acceleration and deceleration waveform, 42 motor no load up to 2500RPM or more
