2.UART mode ：
Advantages of the UART mode:
The motor current can be set arbitrarily via the firmware.
Microsteps can be set as required via the firmware (up to 256 actual microsteps);
Actual and interpolated microsteps can be combined to achieve maximum torque.
The firmware can switch stealthChop2 and spreadCycle modes dynamically via UART.
If the motor is not moving, the motor standby current can be reduced dynamically (via UART).
