1.With ultra-quiet effect .Set 16 microsteps ,and it will be expended to 256 microsteps by differential algorithm .
2.SPI model adjustment .Directly adjust the stepper driver current on the firmware .
3.Support both stealthChop and spreadCycle model.
4.Implement SENSORLESS-HOMING function through configuring the firmware.
5.Optimize the internal chip to greatly reduce the lose step and offset problems.
