[M2A23] Control the Dashboard Pointer

Application	This example code uses the M2A23 series microcontroller (MCU) to control the pointer of the agricultural machinery dashboard.
BSP Version	M2A23_Series_BSP_CMSIS_V3.00.001
Hardware	NuMaker-M2A23SG V0.1

This example code is based on the M2A23 platform and implements precise control of a dedicated two-phase, four-wire stepper motor. It is suitable for pointer drive applications on agricultural machinery dashboards and various other instruments. The system primarily includes two core functions:

Automatic Zeroing Calibration at Startup: When the system starts, the motor first locates the mechanical zero point to establish a physical reference. It then calibrates to the dashboard zero point, ensuring accurate pointer indication.

Periodic Reciprocating Motion: After initialization, the system controls the pointer to perform periodic reciprocating swings between the "zero point" and the "set target position" to verify the driving performance.
