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.
